16. Abstract
Truck parking is a critical goods movement issue that impacts daily safety and operations of the trucking
industry, the traveling public, and the broader community. Truck parking demand arises from the need for long
and short rest breaks as required by Federal and State rules, parking to stage (or wait) to access a customer,
emergency parking, and other operational needs. The Federal Highway Administration (FHWA) has developed
the Truck Parking Development Handbook to help planners, policymakers, and other practitioners understand,
assess, and address the truck parking needs within their jurisdictions. This Handbook includes information to
understand the nature of truck parking needs, estimate parking demand, estimate benefits and costs of parking
facilities, site and design facilities, and implement strategies that promote parking development.

EXECUTIVE SUMMARY
The U.S. economy depends on the trucking industry. According to FHWA’s Freight Analysis
Framework (FAF) 5.1, trucks carry over 19 billion tons of freight valued at more than $18
trillion annually in the U.S. This represents 67 percent of all the freight moved in the U.S. by
weight and 73 percent by value.
1
According to the Federal Motor Carrier Safety Administration
(FMCSA), in 2019, there were 10,160,433 single-unit trucks (straight trucks), and 2,925,210
combination trucks (tractor-trailers) registered in the U.S.
2
There are nearly seven million
commercial vehicle drivers in the U.S. and 3.4 million drivers that operate in interstate
commerce.
Just as the trucking industry is critical to our Nation’s economic success and way of life,
safe, accessible truck parking is critical to the people who drive trucks, the traveling public,
and the broader community. The Federal Highway Administration (FHWA) developed this
Truck Parking Development Handbook to help communities integrate the truck parking
needed to support local industry and commerce that is sited and designed to be compatible
with local community development.
WHY IS TRUCK PARKING IMPORTANT TO MY COMMUNITY?
Since the enactment of Jason’s Law (section 1401 of MAP-21) in 2012, many States and
communities have come to better understand the public benefits of truck parking. Truck parking
shortages are a national concern affecting the safety of commercial motor vehicle drivers and
other roadway users as well as the efficiency of U.S. supply chains. Drivers need adequate rest in
safe places to continue to safely operate on the nation’s roadways and continue to play a vital
role in the American economy. Lack of designated, well lit, secure parking increases personal
risk from a driver safety perspective, as well as driver stress. Providing drivers with safe,
designated places to park reduces the use of locations like highway shoulders, freeway
exit/entrance ramps, vacant lots, and side streets. Averting parking in undesignated locations
improves community safety for all and reduces maintenance costs for repairing highway
shoulders, ramps, and private property not designed for heavy vehicle parking. Communities
often express concern about the impact of truck intensive development on community livability.
The research and case studies presented in this Handbook show how well-planned, well-
designed, and appropriately sited truck parking facilities are positive attributes for economic
development that can support community livability goals.
Demand for truck parking is a culmination of factors determined by the type of parking drivers
require, as summarized in figure 1. Determining where and how much parking is needed at the
local level to accommodate staging and temporary parking requires knowledge about how local
industry supply chains impact communities and land-use planning.
This Handbook explores approaches used in both the private and public sectors to
determine the location of facilities that provide services directly to the trucking industry or

Every day, truck drivers experience frustration as they look for parking to rest, to comply with
State and Federal safety laws, or to stage loads for customer appointments: more than 75 percent
of truck drivers reported regularly experiencing problems with finding safe parking locations in
2019.
3
Since the enactment of Jason’s Law, progress has been made to better assess truck
parking needs, especially those associated with Federal regulations for driver Hours of Service
(HOS) breaks.
In 2015, the U.S. Department of Transportation (USDOT) established the National Coalition on
Truck Parking (the Coalition) with the trucking industry to find common solutions and raise
awareness about the need for additional truck parking.
4
The Coalition formed several working
groups to explore current practices and create products for disseminating information on truck
parking issues and solutions. Working group members also identified the need for a
comprehensive Handbook to address planning for and developing truck parking facilities,
including integration with land use development through improved zoning and design guidance.

WHAT IS IN THIS HANDBOOK?
This Handbook presents tools and strategies for local planners and land use officials to
integrate truck parking into local planning efforts, land use and zoning policy, and
community education efforts to improve the state of truck parking in their communities.
The Handbook covers a wide range of technical issues, making it a valuable reference for local,
regional, and State planners. Its provisions are based on widely accepted and used publications to
provide a sound basis for designing safe, practical, and efficient roadways and associated
facilities. Through planning and land use policies, truck parking can harmonize with community
livability goals. The purpose of this Handbook is to provide State and local practitioners with
resources to plan for, describe the benefits of, and implement truck parking that supports local
economies while minimizing negative externalities. This Handbook presents strategies and case
studies for developing truck parking that:
Support safe freight transportation corridors.
Integrate parking needs with truck demand generating facilities.
Ensure compatibility with adjacent land uses through good siting and design.
While incorporating truck parking with new develop can be implemented over time, this
handbook also highlights case studies where improvements or operational changes have been
made at existing facilities to incorporate some truck parking in the short term. Examples of
creative siting of truck parking, shared usage, and expansion of existing commercial locations
can be found in several reports prepared by the working groups of the National Coalition on
Truck Parking available at:
https://ops.fhwa.dot.gov/freight/infrastructure/truck_parking/workinggroups.
This Handbook provides tools for evaluating truck parking demand and discusses factors
that communities should consider in order to estimate, understand, and address their truck
parking needs. The amount of parking required for a specific development or site will vary
based on the operational conditions of truck demand generators, the function of specific
facilities, driver employment models, and emergency parking.
This Handbook identifies public benefits that arise from providing adequate truck parking.
Projects that increase the availability of truck parking spaces are likely to generate benefits
across several dimensions, making it easier for drivers and reducing both the time spent
searching and the distance traveled to reach available parking. These improvements reduce
trucking costs and impact communities (emissions, congestion, noise, etc.). Availability also
reduces parking in unsafe locations. Truck parking supports local economic development by
generating jobs, income, and tax revenues. The benefits derived from reductions in transportation
costs enhance regional business competitiveness whether they rely on trucks to deliver goods or
provide services to drivers.
This Handbook discusses how to conduct benefit-cost analysis and economic impact
analysis of truck parking projects, following USDOT guidelines and conventions. One of the
hurdles that often prevent agencies from developing or expanding truck parking capacity is the
associated capital and operational costs. The cost and availability of land in urbanized areas may
limit the development of privately- or publicly-owned truck parking. However, understanding
Truck Parking Development Handbook

the monetary value of parking and knowing how to quantify the safety, travel time savings, and
infrastructure preservation benefits, along with the costs and to whom they accrue, may facilitate
the development of safe truck parking through developments led by the public sector, the private
sector, or through public-private partnerships (P3s).
This Handbook provides local planners with information on factors to consider when
identifying and designing locations for truck parking. Transportation logistics, warehousing,
and industry generate significant truck traffic and the need for truck parking in many
communities. The Handbook reviews site selection criteria used by developers to identify truck
stops and businesses that generate significant amounts of truck traffic and, thus, truck parking
demand. Better knowledge about truck parking and freight intensive development siting criteria
can aid in the adoption of effective land-use policies that incorporate the provision of adequate
staging and temporary truck parking. Increased understanding of design requirements for truck
parking facilities is important to ensure safe and efficient truck operations and mitigation of
community impacts.
This Handbook examines attributes that ensure truck parking areas are safe. Suggested
geometric design standards are also provided to give engineering staff a ready resource for
understanding the parking needs of large trucks. The design criteria presented draw from A
Policy on Geometric Design of Highways and Streets, 7
th
Edition (a.k.a., the “Green Book”)
published by the American Association of State Highway and Transportation Officials
(AASHTO) and the California Highway Design Manual (CHDM). The CHDM covers a wide
range of technical issues related to truck parking design, making it a valuable reference for other
jurisdictions. In addition to the parking design, other important features for safe parking
environments include restrooms, lighting, and security features such as fencing, cameras, or on-
site personnel.
This Handbook provides case studies showing successful examples of how communities
have implemented truck parking developments across the nation. The successful
implementation of truck parking depends on collaboration between the public and private
sectors. The barriers to providing needed truck parking are many; funding for facility
construction and maintenance is limited, and finding locations to provide parking is difficult in
the areas with the highest demand due to land cost and availability. Urbanized areas, especially
around industrial, warehousing, or commercial clusters and freight hubs such as ports,
international gateways, and intermodal facilities, have the greatest land-related challenges due to
the concentration of existing development. When local land availability and economic factors
make it difficult to meet truck parking needs, collaboration between public and private partners
has proven to successfully implement shared parking facilities.

1. INTRODUCTION
The Nation’s multimodal freight network plays a critical role in meeting the everyday needs of
communities and businesses. Timely deliveries keep retail food shelves stocked, manufacturing
plants operational, and critical medicine and supplies available. Truck drivers provide critical
connections for freight throughout our communities.
Trucks often function as “warehouses on wheels”
as they make their way to destinations across the
Nation. Long-haul trucks traveling from border
crossings, seaports, and other points of entry make
multi-day trips across the country, necessitating
stops for required breaks and overnight rest. Local
and regional drivers making first and last mile
pickups and deliveries often need to park while
waiting for their designated loading/unloading time.
To meet these demands, truck drivers depend on
sufficient truck parking in communities throughout
the country. The inability to find safe, authorized parking can result in fatigued drivers and
unsafe driving conditions, loss of productivity and income, increased congestion, and higher
costs for businesses and consumers.
America relies on trucking to support consumer needs, serve the housing and construction
sectors, improve quality of life, and sustain economic competitiveness. Activities such as buying
ingredients at the grocery store or receiving an online purchase at home depend on trucks making
deliveries to warehouses, fulfillment centers, and other commercial/industrial centers. Over
many decades, manufacturing and consumer buying preferences have increased the demand for
time-sensitive trucking services. Meanwhile, many urban and suburban communities’
populations have increased, forcing freight intensive developments such as warehousing,
distribution, and manufacturing to rural communities.
Land use policy and development practices in urban and suburban communities have shifted to
include more live-work-play options and complete-streets implementation. This roadway design
practice which typically includes designated facilities accommodating pedestrians, bicycles,
transit vehicles, and automobiles. These developments can create additional challenges for
trucking operations, increasing the demand for truck parking while limiting opportunities to add
safe, efficient, authorized truck parking. This Handbook will help address these issues by
providing guidance for incorporating trucking operation needs into planning and development.
WHY DO TRUCKS NEED TO PARK IN OUR COMMUNITIES?
As freight activity and the vehicles that move goods and facilitate services have increased
throughout the country, some communities have pushed back. Some cities have forced freight
intensive land uses (warehousing, manufacturing, distribution centers, etc.) to move away from
urban population centers in response to citizen complaints about noise and traffic. Pushing truck
parking areas further into the suburbs or banning truck parking altogether can lead to additional
truck traffic issues, reducing economic competitiveness and compromising the time-definite
According to FHWA’s Freight Analysis
Framework (FAF) 5.1, trucks carry over
19 billion tons of freight valued at more
than $18 trillion annually in the U.S.
This represents 64 percent of all the
freight moved in the U.S. by weight and
72 percent by value.

delivery needs of many businesses. By definition, freight-intensive land uses generate demand
for freight movement, often requiring truck activity even when other modes are also used.
Appropriate planning and policy can alleviate most community concerns and provide sound,
proactive land use strategies.
Truck drivers need to park for many reasons and there are unique challenges for various types of
parking needs (see figure 2). Drivers must adhere to Federal and State hours of service (HOS)
regulations that place time-definitive limits on driving and rest intervals; modern supply chains
and consumer buying habits also influence parking patterns. Finally, truck drivers are essential
workers who need to take breaks for rest and safety. A primary goal of this Handbook is to
provide local communities with recommendations and practices they can use to create adequate,
safe, and appropriately located truck parking. More detailed information addressing this topic is
included in chapter 2.

WHY IS THE LACK OF SAFE TRUCK PARKING A PUBLIC CONCERN?
The lack of safe, convenient, and available parking along corridors forces truck drivers to make
difficult choices with potentially dangerous consequences. Therefore, providing truck parking
also benefits the traveling public, consumers, and communities. Potential impacts include:
Safety: A lack of available safe parking forces some truckers to drive longer than is safe while
they search for a place to stop to rest or to park illegally, endangering themselves and, when

parked on the side of the road, creating a hazard for the motoring public. Lack of designated,
well lit, secure parking increases personal risk from a driver safety perspective.
The Moving Ahead for
Progress in the 21st
Century Act (MAP-21)
sought to address the
shortage of truck parking
nationally through
Jason’s Law,
5
which
gathered information on
long-term parking for
commercial motor
vehicles on the National
Highway System (NHS)
to improve the safety of
motorized and non-
motorized users and for
commercial motor
vehicle operators.
Specifically, Jason’s Law
requires the USDOT to
conduct a survey and
comparative assessment
in consultation with
relevant State motor
carrier representatives to:
Evaluate the capability of each State to provide adequate parking and rest facilities for
commercial motor vehicles engaged in interstate transportation.
Assess the volume of commercial motor vehicle traffic in each State.
Develop a system of metrics to measure the adequacy of commercial motor vehicle parking
facilities in each State.
Law Enforcement Dilemma: When truck drivers are tired or reach the limit of how long they
can legally drive without having found an appropriate parking location, they must choose
whether to park illegally or drive illegally. This presents a difficult problem for law enforcement
faced with trucks parked along highways or roadway shoulders. Parking on shoulders or ramps
of a limited-access highway is prohibited in most States and poses a hazard to other motorists;
however, having fatigued drivers operate beyond the Federal HOS regulations can also be
dangerous.

Safe truck parking came into the national spotlight in 2009
following the murder of 35-year-old Jason Rivenburg, a husband,
father, and a truck driver. On March 4, 2009, Jason stopped for a
delivery in Virginia and then headed toward a delivery destination
in South Carolina. While only 12 miles from the delivery location,
he needed to find parking to rest through the night since his arrival
location was not yet open to receive deliveries. Jason did not have
a safe place to park. Jason had heard from truckers familiar with
the area that a nearby abandoned gas station was a safe location to
park for the night. Tragically, he was attacked and murdered at this
location while he slept; his killer took both his life and just $7.00
that he had in his wallet.
Following his death, Jason’s widow, Hope Rivenburg, advocated
alongside family, friends, and representatives of the trucking
industry to pass Jason’s Law under the Moving Ahead for Progress
in the 21st Century (MAP-21) Act in 2012. Jason’s Law
established truck parking safety and security as a national priority
and requires the U.S. Department of Transportation (USDOT) to
regularly evaluate the need for safe truck parking.

Preservation of Public Infrastructure: When drivers cannot find authorized parking and reach
the end of their HOS, they might park on roadway shoulders or ramps. Frequent stops and starts
from heavy trucks create more wear than the infrastructure was designed for, often leading to
pavement rutting and cracking of the roadside. The need to do shoulder reinforcements and
repairs can be costly for local and State governments which already face funding shortfalls.
Funding spent on these repairs may take away from needs in other areas.
Impacts to Shipping Costs and the Economy: A survey conducted by the American
Transportation Research Institute (ATRI) documented the amount of lost revenue-earning time
that drivers experience by parking earlier than they otherwise needed to find parking. With an
average of 56 minutes of revenue drive time sacrificed by drivers per day, the parking shortage
effectively reduces an individual driver’s productivity by 9,300 revenue-earning miles a year,
which equates to lost wages of $4,600 annually.
6
These costs are either passed onto shippers, and thus consumers, or absorbed by drivers. Either
way, they increase the cost of doing business and the cost of consumer goods. Difficulty and
costs associated with finding safe, reliable truck parking can also negatively impact driver
retention and recruiting, exacerbating an already tight labor market. The American Trucking
Associations (ATA) estimate that the driver shortage hit a historic high of over 80,000 drivers in
2021.

Without enough drivers, manufacturers and retailers must increase inventories to avoid
stock outs, thus increasing inventory carrying costs and ultimately, consumer prices. In addition,
to get the just-in-time service required to meet today’s supply chain demands, shippers often pay
premiums for guaranteed on-time deliveries. All these factors add to overall freight
transportation costs, supply chain costs, and overall economic competitiveness.

HOW DO COMMUNITIES ADDRESS THE NEED FOR TRUCK PARKING?
Many communities view “big-rig” parking in their communities unfavorably, focusing on
negative aspects of truck parking like noise, emissions, and litter. Since the adoption of Jason’s
Law, USDOT and States have worked to educate communities about the benefits associated with
providing truck parking facilities, as noted above. Truck parking facilities can instead be a
positive attribute as part of modern logistics centers, making communities more attractive to site
developers, increasing local jobs and tax revenues, and reducing negative impacts associated
with trucks parked in unauthorized areas.
In 2015, the USDOT and several stakeholder organizations established the National Coalition on
Truck Parking (the Coalition), responding to the documented need for truck parking solutions.
Coalition members include the trucking industry, commercial vehicle safety officials, State
departments of transportation (DOTs), and commercial truck-stop owners and operators. In 2016,
the Coalition held meetings around the country to get input from key stakeholders on approaches
to solve the Nation’s truck parking problem. Recognizing the need for a venue to implement

ideas brought forth by stakeholders, the Coalition convened Working Groups around key topic
areas. The Coalition Working Groups met from November 2017 to July 2019 to explore current
practices and create products for disseminating information on truck parking issues and
solutions. Working group members also identified the need for a comprehensive handbook to
address planning for and developing truck parking facilities, including how to integrate truck
parking with land use development through improved zoning and design guidance. More
information about these topics is included in chapters 3 and 4.
WHAT IS THE PURPOSE OF THIS TRUCK PARKING DEVELOPMENT
HANDBOOK?
This Handbook is a resource for entities that develop and
operate truck parking facilities or facilities that create trucking
activity that may require truck drivers to park for safety,
regulatory, or work duty reasons. This Handbook presents
tools, design guidance, and case studies suggesting how truck
parking can be viewed as a development opportunity and key
element of sound local land use practices.
WHAT IS INCLUDED IN THE HANDBOOK?
This Handbook presents tools and strategies for local planners
and land use officials integrate truck parking into land use
plans and improve the state of truck parking in their
communities.
Chapter 2, “Quantifying Truck Parking Needs, Benefits, and Costs,” presents three topics
intended to inform planning and engineering practitioners about the importance of truck parking
in supporting the Nation’s economy, way of life, and how it impacts local communities:
The National Truck Parking Shortage presents facts and data about the importance of the
trucking industry and the need for adequate parking opportunities for the safety of truck
drivers and other road users.
Estimating Truck Parking Demand in Your Community provides recommendations to help
planners estimate truck parking demand generated by industrial, warehousing, and
commercial land uses.
Benefits and Costs of Truck Parking reviews the benefits (safety, time savings, emissions,
etc.) and costs (capital, operations, and maintenance) associated with truck parking projects.
This section also provides practitioners information on evaluating projects using benefit-cost
analysis (BCA) and presents case study examples.
Chapter 3, “Siting and Designing Truck Parking Facilities,” examines truck parking at the
community level and provides information on including truck parking in current and planned
commercial/industrial developments.

Siting Truck Parking Facilities identifies some of the factors used by retail, commercial,
and industrial site developers to locate facilities that will generate significant truck traffic and
demand for truck parking. The section also explores land use considerations for siting and
integrating truck parking into local communities through several case studies. These case
studies address new development as well as examples of how truck parking can be integrated
at existing facilities.
Designing Truck Parking Facilities provides recommendations to local planning and
engineering staff for geometric design considerations, and compatible amenities such as
lighting, fencing and other safety features.
Chapter 4, “Encouraging and Requiring Truck Parking,” provides tangible steps for use in
addressing the truck parking shortages.
Improving Land Use and Zoning Policies discusses how land use policies have failed to
keep pace with modern shipping practices. Communities can benefit from reviewing land use
and zoning policies to ensure they encourage adequate truck parking for new developments
that generate truck traffic.
Case Studies of Successful Local Truck Parking Developments presents real examples of
communities that have addressed truck parking needs.

2. QUANTIFYING TRUCK PARKING NEEDS, BENEFITS, AND COSTS
In 2019, tractor-trailer combinations carried nearly three-quarters of the Nation’s freight by
weight and 80 percent by value and traveled more than 175.3 billion miles on our Nation’s
roadways.
9
While there was a decline in vehicle-miles traveled (VMT) for tractor-trailer or
combination trucks in 2011 and 2019, the trend over the past decade is clear; truck travel is
growing (figure 3). When single-unit trucks are included, truck vehicle-miles traveled climb to
more than 300 billion in 2019, a 12-percent increase from a low in 2011. Single-unit truck miles
of travel have steadily climbed since recovery from the recession in 2008.
Figure 3. Line chart. National combination truck vehicle-miles traveled (2009-2019).
(Source: U.S. Bureau of Transportation Statistics, 2021.)
Combination trucks are typically used for regional and interstate travel over long distances.
Long-haul operations require more hours on the road, with trips often lasting multiple days,
creating demand for overnight parking and rest. Modern logistics relying on practices like just-
in-time or lean manufacturing, require drivers to stage their loads to meet tight delivery
windows. The FHWA projects that trucks will remain the central mode of transport in American
commerce; FHWA estimates a 1.5 percent average annual growth in combination truck vehicle-
miles between 2017-2030.
10
As a critical component of the Nation’s commerce, the trucking industry is also an important
jobs creator. According to the ATA, trucking activities supported 7.95 million workers in the
economy in 2019excluding those self-employed. Of that number, the industry employed 3.6
million truck drivers.

THE NATIONAL TRUCK PARKING SHORTAGE
Every day, thousands of truck drivers experience frustration as they look for parking to rest,
comply with State and Federal safety laws, or stage loads for customer appointments.
Transportation planning professionals should be aware that truck drivers are held to strict
adherence to HOS regulations using electronic logging devices (ELDs) that precisely track the
time, location, speed of travel, and other travel attributes. As a result, truck drivers nearing the
end of their allowable drive time may need to stop immediately. Alternatively, drivers may
choose to stop in a location far from their destination to ensure they can find parking, losing
productivity and creating demand for truck parking outside of congested urban areas. The failure
to locate safe parking near a route or a shippers’ facility often leads to desperation, and drivers
may need to park in undesignated areas like ramp shoulders, side streets, or abandoned lots.
For public agencies, the lack of designated truck parking typically makes a challenging issue
worse; through premature damage to roads not designed to handle heavy loads, higher crash risk
from trucks parked in the right-of-way or on side streets, and complaints from residents. For
drivers, the stress of finding legal parking is just one of many concerns. The time spent looking
for parking results in lost productivity and lost wages. Parking illegally or in undesignated areas
often presents the risk to personal health and safety, fines, cargo theft, or vehicle damage.
According to the National Highway Transportation Safety Administration (NHTSA), 885 large-
truck drivers died in 2018 and 4,678 total people died in collisions with trucks.
12
Providing over-
the-road truck drivers with safe opportunities to park improves safety for all road users. In one of
the most extensive crash analyses of its kind, the Large Truck Crash Causation Study found that
13 percent of commercial motor vehicle (CMV) drivers were considered fatigued at the time of
their crash.
13
To prevent incidents involving fatigued truck drivers, Federal regulations at 49 CFR part 395
require that drivers hauling loads in interstate commerce adhere to HOS rules set by the FMCSA.
The HOS requirements largely dictate when, where, and how long truck drivers must park for
rest. Table 1 shows the current Federal HOS rules. The FMCSA also requires interstate carriers
to use ELDs to record driving hours to ensure compliance (49 CFR 395.8).
Table 1. Summary of Hours-of-Service (HOS) rules for property-carrying drivers.
Rule Description
11-Hour
Driving Limit
May drive a maximum of 11 hours after 10 consecutive hours off duty. (49
CFR 395.3(a)(3)(i)). May be extended by up to 2 hours when a truck driver
encounters adverse driving conditions. (49 CFR 395.1(b)(1)).
14-Hour
Limit
May not drive beyond the 14th consecutive hour after coming on duty,
following 10 consecutive hours off duty. Off-duty time does not extend the
14-hour period. (49 CFR 395.3(a)(2)). May be extended by up to 2 hours
when a truck driver encounters adverse driving conditions.

Rule Description
30-Minute
Driving Break
Drivers must take a 30-minute break when they have driven for a period of 8
cumulative hours without at least a 30-minute interruption. The break may be
satisfied by any non-driving period of 30 consecutive minutes (e.g., on-duty
not driving, off-duty, sleeper berth, or any combination of these taken
consecutively). (49 CFR 395.3(a)(3)(ii)).
60/70 Hour
Limit
May not drive after 60/70 hours on duty in 7/8 consecutive days. A driver
may restart a 7/8 consecutive day period after taking 34 or more consecutive
hours off duty. (49 CFR 395.3(b)-(c)).
Sleeper Berth
Provision
Drivers may split their required 10-hour off-duty period, if one off-duty
period (whether in or out of the sleeper berth) is at least 2 hours long and the
other involves at least 7 consecutive hours spent in the sleeper berth. All
sleeper berth pairings must add up to at least 10 hours. When used together,
neither time period counts against the maximum 14- hour driving window.
(49 CFR 395.1(g)(1)(ii)).
Short-Haul
Exception
A driver is exempt from the above requirements if: the driver operates within
a 150 air-mile radius of the normal work reporting location, and the driver
does not exceed a maximum duty period of 14 hours. Drivers using the short-
haul exception must report and return to the normal work reporting location
within 14 consecutive hours and stay within a 150 air-mile radius of the work
reporting location. (49 CFR 395.1(e)(1)).

In 2015, FHWA conducted the first Jason’s Law Truck Parking Survey and Comparative
Assessment.
14
Among the study conclusions:
Most States report problems with truck parking shortages.
Those States that did not report shortages were mostly rural (except for Ohio).
States report higher levels of shortages in public parking facilities than in private facilities.
States with the highest numbers of spaces are clustered along major corridors with high truck
volumes.
In 2019, FHWA updated the Jason’s Law Truck Parking Survey and Comparative Assessment.
15
The new assessment found that the truck parking shortage identified in the 2015 report persists.
Shortages occur at every time of day, in every State, and throughout the year. Challenges are
more acute on major freight corridors, such as busy interstates, and in cities that act as freight
hubs. Key observations from the 2019 survey include:

More than 90 percent of drivers reported that parking was difficult to find between 7 PM and
midnight, and more than 60 percent reported difficulty between midnight and 5 AM.
Truck-stop operators reported a similar pattern of parking constraints, with the busiest times
occurring overnight and some level of constraint throughout the day.
The inventory found an average of 10.0 publicly-owned parking spaces per 100,000 daily
truck vehicle miles traveled.
The Southwest region has the lowest number of parking spaces per miles of travel, with
Texas, Arkansas, Louisiana, and Oklahoma having the lowest ratio.
Approximately 2,000 public and 27,000 private truck parking spaces were added since 2015.
The 2019 Jason's Law Survey Update also found that challenges related to planning, funding,
and finding locations for truck parking persisted.
The 2019 Jason’s Law Survey Update notes that local government involvement and education
are needed to improve conditions. The need is particularly prevalent in urban areas where truck
parking likely conflicts with nearby land uses and where the need for load staging most directly
conflicts with higher land costs. The 2019 study noted that the 32 urbanized areas with the
greatest number of freight origins/destinations only have 8.5 percent of the total truck parking
spaces. Since zoning and land use development guidelines are most often decided at the local
level, the study results indicate that outreach and education of local officials may be beneficial to
addressing truck parking needs.
The demands for truck parking extend beyond just complying with HOS regulations. Truck
drivers may need to park while waiting on their shipping and receiving appointment schedule
which is set by the customers. Despite customer needs, shippers and receivers often do not
provide space for drivers to park and wait for scheduled appointments. Additionally, despite
popular belief, truck parking at big box retailers is not widely allowed, and permission to park at
large retailers can change at any time based on policies set by shopping center owners or local
ordinances.
Nationwide, respondents to the Jason’s Law Survey Update echoed common issues, noting that
citizens and local governments need to better understand trucking operations and the value
communities receive from prioritizing infrastructure like truck parking. Increasing awareness and
understanding of this vital industry can also improve local planning, zoning, and regulatory
decisions to serve the community at large. At the same time, truck parking facilities can be
designed to mitigate community impacts and concerns.
ESTIMATING TRUCK PARKING DEMAND IN YOUR COMMUNITY
Every community has different generators of truck parking demand. Local manufacturing,
warehousing, and distribution activities depend on timely trucking service, which in turn depends
on designated and predictable truck parking. Rail, marine, and air intermodal hubs as well as
international border crossings can also generate significant parking demand within and outside of
the gates of the facilities. Even in communities with relatively low industrial activity, retail
business, agriculture, natural resource extraction, and through traffic on a major highway can
lead to high truck parking demand.
Truck Parking Development Handbook
15
Understanding Demand in Your Community
The first step in understanding where, when, and why truck drivers are parking in your
community is identifying the infrastructure and industries that attract truck traffic. Crowdsourced
information on parking availability can help determine the areas of high demand; there are
mobile applications that collect and share this information. Additionally, awareness of oversize
or overweight truck traffic traveling to, from, or through your community is essential. These
loads can be subject to additional constraints related to routing, hours of operation, and parking
that influence when and where parking is feasible. Table 2 summarizes information practitioners
should seek to characterize truck parking demand in their communities. Collaboration with State,
regional, and local planning partners, including economic development corporations attuned to
industry needs, can help answer many of these questions efficiently.

(Source: FHWA, 2021.)
State, regional, or local collaborators may be able to provide data or plans related to truck
parking. Many States and regions have conducted detailed truck parking studies in response to
the findings of Jason’s Law, the national truck parking shortage, and the negative safety and
mobility impacts of truck parking in undesignated areas. Planning and engineering practitioners
can benefit from coordinating with their planning collaborators and adjacent jurisdictions to
determine whether data have been collected on truck parking demand, utilization at rest areas,
and safety impacts related to unmet truck parking demand.
Gaining perspective on the greater context of truck parking is also important because not all
parking demand occurs directly adjacent to industrial uses. The same truck driver may begin a
journey at a shipper, park overnight at a rest area or truck stop, park again to stage near their
delivery, and end the journey at the receiver (figure 4). The first parking stop may occur
hundreds of miles away from the receiver. The second parking stop could occur within a mile of
the receiver, or it could occur 90 miles from the receiver. The driver will determine the best
location for both parking stops based on several factors, including anticipated or actual
availability of truck parking near their destination, anticipated or actual congestion between the
parking location and the destination, amenities offered at various parking locations, contract
obligations between trucking companies and truck stop operators, peak hour tolls, and personal
preferences. It is also important to recognize that drivers cannot rely on restrooms, water, or
other amenities at customer sites, and they may need to make additional local stops to fulfill
these needs.

Estimating Truck Parking Demand at a Site
As truck-served facilities are developed or expanded, the truck parking impacts of increased
truck traffic can be evaluated. Truck parking demand generated by a site should be included in
the traffic impact analysis process used by municipalities to systematically evaluate and
accommodate truck parking demand as the industrial base of a community grows. Ad-hoc
estimations or estimations at existing sites can also provide insight into current and future truck
parking demand for a specific development.
National and regional studies have been conducted to develop estimates of the number of truck
parking events generated per employee, per square footage, or per truck bay at a given site. Four
notable case studies on estimating truck parking demand are highlighted below.
Case Study 1: National Cooperative Freight Research Program (NCFRP) Research Report 37
NCFRP Research Report 37: Using Commodity Flow Survey Microdata and Other
Establishment Data to Estimate the Generation of Freight, Freight Trips, and Service Trips:
Guidebook is a 2016 publication.
16
This research combined survey data from New York and
New Jersey establishments with data from the national Commodity Flow Survey to estimate
freight trip generation rates. The report further estimates peak freight and service vehicle parking
demand in Application 1 using the following assumptions:
Twenty-five percent of all freight trips generated take place in the peak hour.
Service trips are uniformly distributed throughout an 8-hour workday.
Delivery vehicles occupy a parking space for 0.5 hours.

estimate-the-generation-of-freight-freight-trips-and-service-trips-guidebook.
Truck Parking Development Handbook
18
Service vehicles occupy a parking space for 1.5 hours.
While this research is helpful for estimating trip generation based on employment and industry,
there are some limitations to its applicability to truck parking demand:
Some industries in the North American Industry Classification System (NAICS) are not
included.
The establishment sample included mostly large establishments, and smaller establishments
(by employment) may have a different rate of production per employee due to economies of
scale.
The sample is concentrated in the Northeast U.S., and application to other regions of the
country with different development patterns may be inaccurate.
Peak generation, time-of-day distributions, and parking-specific data are not included in this
research. However, assumptions were developed in one of the practical applications.
See Application 1: Quantification of Commercial Parking Needs for a Commercial Center in
NCFRP 37 for a sample application of this model.
Case Study 2: Strategic Highway Research Program 2 (SHRP2): Winston-Salem Innovations
in Local Freight Data
The Winston-Salem Metropolitan Planning Organization (MPO) proposed one of seven projects
selected to develop and pilot innovations in local freight data under the Strategic Highway
Research Program 2 (SHRP2) Implementation Assistance Program.
17
The MPO and its planning
partners faced challenges in planning for freight movement because the regional travel demand
model was not sufficiently describing freight flows in the region. One major challenge facing
practitioners in the region was a shift from the historically dominant textile industry to broader
freight distribution and logistics activity. The research effort conducted under SHRP2 included
identification of data needs, interviews with peer MPOs, identification of freight nodes, and a
comprehensive survey of freight facilities in the Winston-Salem region. The survey resulted in
estimates of daily truck trip generation for each of four site types: distribution center, intermodal
facility, retail, and shipper (or manufacturer).
The project estimated the relationships between these factors, including equations to estimate the
number of daily truck trips for each facility type based on the number of truck bays. These
equations can be used in lieu of the employment-based estimates from NCFRP 37 and are shown
in figure 5.

bays.

2016.)
This research provides an alternative to employment-based estimates. This approach can be
beneficial for estimating trip generation at a site with an unknown future tenant, such as
speculative industrial and warehousing developments. Practitioners should be aware of the
following limitations:
This model uses facility role rather than industry to classify data. The amount of freight
generated by shippers varies significantly by industry, resulting in a weak relationship
between truck bays and daily truck trips for shippers when all industries are grouped
together.
Data from this region may not be directly transferable to another.
Additional assumptions are needed to develop truck parking generation rates based on these
truck trip generation rates.
Case Study 3: Maricopa Association of Governments (MAG) Truck Parking Study
The 2021 MAG Truck Parking Study used truck global positioning system (GPS) data from
ATRI to determine when, where, and for how long trucks stopped in the region. The study
included a comparison of stops to land uses, enabling estimation of the number of truck trips
Truck Parking Development Handbook
20
generated by various industries. The study estimated parking activity rates per employee for
industrial and commercial establishments categorized at the two-digit and three-digit NAICS
level. These estimates were the primary data source used in the development of the FHWA truck
parking demand estimation tool, discussed below. Notably, the study found that industrial land
uses created the highest amount of truck trips and the longest duration of stopped trucks
(figure 6). The MAG study also found that truck parking demand during the peak parking hour
was approximately twice the average for the rest of the day.
Figure 6. Bar chart. Truck stop data by land use in the Maricopa region.
(Source: Maricopa Association of Governments, 2021.)
The following limitations should be considered when interpreting these findings:
ATRI data include a sample of trucks that typically overrepresent large fleets. Independent
owner-operators and small fleets may not be fully included. An expansion factor was
developed to account for this during the study and was uniformly applied across the region.
The trip generation rates developed do not distinguish between stops at generators to park or
stage and stops to pick up or drop off a load.
Rates should be interpreted as total trucks that need to be accommodated at a site.
Data from this region may not be directly transferable to another.
Case Study 4: Texas A&M Transportation Institute Truck Trip and Truck Parking Generation
Using Truck GPS Data
The Texas A&M Transportation Institute (TTI) developed several case studies using truck GPS
data. The study included data from sites in Texas and Maryland, and it included analysis of truck
parking generated off-site (e.g., at rest areas) by industrial land uses. The analysis of off-site
parking included stops both before and after the study site. The locations studied included:
Port of Houston, Bayport (Houston, Texas): Traditional Port Area.
Cedar Port (Houston Area, Texas): Industrial Warehouse Near Major Port.

Alliance (Dallas, Texas): Major Industrial Facility with Warehouse, Distribution, and

Agribusiness Facility (Salisbury, Maryland): Agricultural Processing Facility.
Rural Crossroad Industrial cluster (Hagerstown, Maryland): Rural Area Industrial Clusters at
Crossroad of Major Interstates and Nearby Rail Intermodal.
Notably, this study provided insight into truck parking that supports a specific site, including
parking that occurs at other truck parking or industrial locations. This analysis found that more
than 85 percent of presumed parking stops were located within 50 miles of the truck driver’s
destination (see table 3).

FHWA’s Truck Parking Demand Estimation Tool
Findings from these case studies can be used to develop a planning level tool that allows local
planners to estimate the demand for truck parking for freight-intensive land uses and
developments at a high level. The Truck Parking Demand Estimation Tool allows practitioners
to quickly estimate the peak number of trucks requiring parking. Estimates from this tool can
help practitioners establish truck parking requirements at new industrial developments, assess a
community’s current ability to handle new truck parking demand, and plan for increased truck
traffic in a community. Table 4 summarizes the parking generation rate for every 100 employees
for the NAICS industries with sufficient data. The tool also provides estimates for certain three-
digit NAICS codes and estimates of spatial distribution of truck parking demand. Manufacturing
facilities should be evaluated using three-digit NAICS codes whenever possible due to
significant variation in product types, sizes, and shipping needs. The parking generation rates
used at the two-digit and three-digit level come from the 2021 MAG study.

these values should be applied with caution.
Note: Variation within industries may be significant based on the size of operations and
commodity types shipped to and from the facility.
(Source: Maricopa Association of Governments, 2021).
As with each of the case studies, the Truck Parking Demand Estimation Tool for estimating truck
parking demand at sites has limitations. Practitioners should consider:
Variation within industries may be significant based on the size of operations and commodity
types shipped to and from the facility. For example, a vehicle manufacturer with 1,000
Understanding NAICS Codes
NAICS codes are used to describe the goods or services produced by an establishment. An
establishment may have multiple co-located functions, such as a primary function as a
manufacturing facility and secondary warehousing activities on site. The primary purpose of
the establishment will determine the NAICS code applied to a location. The source data for
this analysis categorized different sites of the same business separately based on the primary
function of that site. As a result, a distribution center supporting a retail business would be
classified under 48-49 Transportation and Warehousing, while the retail stores would be
classified as 44-45 Retail Trade.

employees will generate a different volume of freight than a packaged food manufacturer of
the same size.
Estimates are based on employment-based studies conducted between 2016 and 2021. As
workplace automation and efficiency increases, the output per employee will increase.
Additionally, facilities may co-locate staff not directly related to freight production, such as
marketing or accounting. Individual sites may have a different ratio of freight-producing
employees than typical within a NAICS sector.
The tool includes the option to override the employment-based estimates with a known daily
truck volume. Working with economic development corporations and future tenants to
understand daily truck volumes will improve the accuracy of these estimates.
BENEFITS AND COSTS OF TRUCK PARKING
Two of the hurdles that often prevent agencies from funding truck parking capacity projects are
the associated capital and operational costs. In order to justify these costs, accurate information is
needed to quantify the safety benefits, travel time savings, and asset preservation savings from
the provision of truck parking. Understanding the benefits and costs and to whom they accrue is
important to support funding to develop adequate safe truck parking.
When to Use the FHWA Truck Parking Estimation Tool
The estimation tool combines research from many sources and regions of the Nation to make
methods more widely accessible to practitioners. This tool applies to truck parking demand
from commercial and industrial development, and it does not include approximation of parking
demand from through traffic. There are several ways to use the estimation tool:
Estimate parking generated by a specific development: This tool can be used to
develop a baseline estimate for negotiation with developers. All sites will generate
truck parking demand, and the tool provides a starting point for discussions related to
a specific location as well as wider community impacts.
Estimate parking impacts of hypothetical changes in land use: Communities
throughout the country are experiencing changes in warehousing and distribution
patterns, including where facilities are locating and how the trucking industry serves
them. This tool can be used to estimate the impact of anticipated increases in
industrial development on truck parking demand. For example, what would happen if
our manufacturing base grew by 2,000 employees? Scenarios should align with
economic development goals to plan for future parking needs.
Develop guidelines for your community’s truck parking requirements: Policymakers
can assess how various measures for requiring on-site parking (employment, square
footage, and loading bays) result in different peak parking requirements. The tool can
also be used for sensitivity testing to confirm whether a guideline will meet the truck
parking needs for scenarios anticipated in your community. For example, a
speculative site may have an unknown tenant and industry, or workplace efficiency
could change production per employee.
Truck Parking Development Handbook

Projects that increase the availability of truck parking spaces are likely to generate benefits
across several dimensions, making it easier for drivers to find a space by reducing both the time
spent searching for parking and the length of detours needed to reach an open space. These
improvements not only reduce trucking costs, but they also reduce the negative impacts of
trucking on communities (emissions, congestion, safety, etc.). Making it easy to find parking will
also reduce the need for truck drivers to park in undesignated locations, many of which are
unsafe and are a nuisance for local communities. Many truck drivers end their drive early to
avoid running out of HOS and having to park in undesignated locations. This truck parking
safeguard decreases the productivity of the sector and leads to higher costs. Increasing parking
availability can improve the productivity and reliability of the trucking sector.
Truck parking projects may also generate broader economic development impacts. Economic
development impacts include jobs, income, and taxes generated in the economy. These benefits
derive from reductions in transportation costs that in turn enhance regional economic
competitiveness, from attracting and retaining business establishments that serve truck drivers in
the surrounding area, and from the operations of the parking facility.
This section provides guidance on how to conduct benefit-cost analysis and economic-impact
analysis of truck parking projects, following USDOT guidelines and conventions. This section
describes the main sources of benefits (decreased undesignated parking, avoided detours,
improved productivity, improved reliability, and other), and discusses the estimation of costs
(capital and operations and maintenance). Economic impacts are then discussed separately, as
these provide an additional valuable perspective to project development. Finally, this section
concludes with a summary of two case studies that demonstrate how a benefit-cost analysis can
be used to demonstrate how a truck parking project will have a positive impact on the
community.
Truck Parking Benefits
USDOT publishes guidance for conducting BCAs, including which benefits can be consistently
monetized.

In addition, USDOT has conducted annual meetings on truck parking with
stakeholder groups as well as facilitated over 20 workshops with States and MPOs. Information
from these meetings supports the following observations on truck parking. The guidelines as of
2021 were used to outline specific benefits associated with truck parking. The quantitative
benefits of truck parking projects are summarized below:
Safety for truck drivers.
Safety for other motorists.
Enhanced security for truck drivers.
Reduced emissions of pollutants.
Reduced trucking costs.

Reduced congestion.
Reduced infrastructure deterioration.
Other benefits.
The above benefits are provided from the following outcomes of increased truck parking access:
Decreased undesignated parking.
Avoided detours while searching for truck parking.
Improved trucking efficiency and productivity.
Improved trucking reliability.
Other factors.
Decreasing Undesignated Parking: Projects that improve truck parking availability will also
reduce undesignated parking in a community. Truck drivers avoid detours to search for parking
as an inconvenience and as an extra cost that cuts into wages and profitability. Drivers park in
undesignated locations along their route—such as on highway shoulders, interchanges, ramps,
and or vacant lots—to avoid unproductive miles or because HOS rules require them to stop and
take mandated rest.
Truck parking in undesignated locations is undesirable and potentially dangerous, and therefore
projects that reduce this activity can generate the following benefits:
Improved Safety: Truck parking in locations that were not designed to accommodate them
pose safety risks to the driver of the truck, the driver and passengers of other vehicles, and
pedestrians and cyclists. Projects that augment designated truck parking supply, thus
reducing undesignated truck parking, can help to mitigate the following safety risks:
o Undesignated parking on roadway shoulders poses a significant crash risk with through
traffic because of the large speed differentials between a stationary parked truck and
motorized travel speeds.
o Undesignated parking on the shoulders can also prevent other vehicles from using the
shoulders, which poses additional safety risks, particularly during emergency situations.
o Roads are designed to give drivers lines of sight onto other vehicles so they can make
safe decisions. However, trucks parked in undesignated locations can obstruct these
lines of sight, reducing the visibility of drivers and making it harder for them to see other
vehicles and anticipate potential conflicts.
o In urban areas, delivery trucks that cannot find curbside parking often resort to parking in
a travel lane while they make a delivery, often in the middle turning lane. Blocking a
travel lane represents a safety risk as other vehicles do not expect the lane to be blocked
and might make avoidance maneuvers, potentially onto incoming traffic.
Improved Security: Undesignated parking places the driver and the cargo at a security risk.
Designated truck parking facilities often have lighting, security cameras, fencing, controlled
access, and other drivers, which make them significantly more secure than undesignated
Truck Parking Development Handbook
26
locations. The driver and cargo at undesignated locations have higher exposure to theft,
damage, and driver assault. Projects that reduce undesignated parking reduce these risks,
benefiting the drivers, the trucking companies, and the owners of the cargo.
Other Considerations:
o Undesignated parking at public lots or retail establishments takes up parking capacity
that would otherwise be available for passenger vehicles.
o Drivers parked for a longer period of time (overnight or staging) often leave their engines
running to power heating or cooling systems. This creates noise that impacts nearby
residents.
o Engine idling also results in additional emissions of pollutants relative to parking in a
facility that offers auxiliary power units or other technologies that avoid truck idling.
o Undesignated parking can accelerate infrastructure deterioration, leading to the need
for more frequent repaving or rehabilitation expenses. A heavy truck starting to move
from a stopped position on the side of the road, while turning the front wheels onto the
road, puts significantly greater pressure on the pavement than does a continuously
moving vehicle. In addition, shoulders may not have the same specifications as the
mainline roadway and could be more susceptible to deterioration by heavy vehicles.
Trucks can also hit signs and guiderails while trying to park in an undesignated location.
o Undesignated parking is often associated with litter and waste because drivers do not
have access to needed amenities.
o In urban areas, trucks making deliveries might stop for an extended time on the travel
lane if curbside parking is not readily available, creating roadway congestion and
slowdowns for other vehicles.
Avoided Detours: Truck parking projects that increase the availability of spaces where they are
needed will reduce the detours that truck drivers must make to find an open space or access
needed amenities and services (such as restaurants). This translates into decreased truck travel on
the roadway system, which can be calculated in terms of vehicle miles traveled and vehicle hours
traveled. Decreased truck travel generates the following benefits:
Decreased Trucking Costs: Reducing unnecessary truck travel will decrease the costs of
trucking associated with driver wages, fuel, vehicle costs, etc. In a competitive environment,
these savings tend to be passed onto shippers, and ultimately to customers in the form of
lower-cost products.
Avoided Externalities: Trucks generate externalities because of their size and weight. As
these large and heavy vehicles travel throughout the roadway system, alongside passenger
vehicles, pedestrians, and cyclists, they generate costs to the general public. These costs
include increased crash risk, emission of criteria pollutants, emissions of greenhouse gasses,
and increased congestion. The public sector also faces an additional cost from the premature
deterioration of pavements and additional stress on bridges. Projects that reduce truck travel
in general will generate benefits by reducing these costs.
Reduced Driver Fatigue Safety Risks: Drivers are more likely to be fatigued when searching
for parking, as this comes at the end of their shift, and drivers might even be distracted if they
Truck Parking Development Handbook
27
have difficulty finding a place to rest. Projects that make it easier for truck drivers to find a
spot are likely to reduce these safety risks.
Improved Trucking Productivity: The lack of parking availability often leads truck drivers to
end their day early to avoid running out of driver time under HOS regulations. Recent studies
have found that drivers often end their day early by 30 minutes or more, with some ending their
day early by more than 1 hour.
19
,
20
Drivers can be reluctant to wait until the very end of their day
to seek parking if they believe parking may be difficult to find, instead ending their shift early if
they see available spaces along their route.
Parking projects that make it easier to find a space and allow truck drivers to work more hours
each day will reduce the time that it takes to complete shipments. The additional driving time
will allow the shipment to be completed sooner, reducing time-dependent costs per shipment,
such as driver wages, permits, licenses, insurance premiums, and overhead, among other costs.
ATRI estimated that each hour of additional drive time per day (within HOS limits) reduces
daily trucking costs by 0.8 percent.
21
This value was estimated using conservative assumptions
and could be significantly higher for certain types of trucking.
The limited availability of parking, over a region or corridor, will directly reduce the productivity
of trucking. Over time, the lower productivity of trucking will lead to higher transportation costs,
and, ultimately, higher consumer prices.
Improved Trucking Reliability: The reliability of shipments is an important variable for trucking
companies and shippers.
22
Modern supply chains are highly optimized and depend on freight
arriving at its destination on time. Projects that increase the availability of truck parking can
improve the reliability of transport services along a corridor, especially in dealing with
unforeseen events, such as snowstorms or vehicle breakdowns. More parking options could
allow the truck driver to deal with these circumstances and return to the road as quickly as
possible.
Increasing reliance on just-in-time supply chains for reducing inventory costs places a premium
on shipments arriving during their appointment delivery windows. Truck drivers respond by
increasing the slack,” or buffer time, in their schedule to ensure on-time performance in the face
of traffic congestion and unexpected issues. Trucks that arrive early for a pickup or delivery are
often not allowed to wait on premise, which creates a need for “staging” or temporary parking in

or near industrial and commercial areas. Difficulties finding parking can make it harder for truck
drivers to meet their appointments and decrease the reliability of supply chains.
Other Benefits: Truck parking projects that improve the availability of parking spaces can also
have the following benefits:
Driver satisfaction and retention: Having readily available truck parking decreases the stress
of drivers, particularly on unfamiliar routes, which could improve driver retention. The
amenities available at truck stops and rest areas can also make life on the road easier. All this
could help ameliorate the driver shortage.
Facilitate regulation compliance: Readily available parking would make it easier for
trucking companies to comply with HOS rules. Otherwise, trucking companies and drivers
must spend time and effort planning routes and stops so that they maximize the productive
driving time and be able to find safe parking within the HOS rules. This takes effort, and
might cause stress for drivers, particularly on new routes.
Increased productivity of nondriving time: The amenities and services available at truck stops
allow truck drivers to be productive during nondriving time, and even to get better rest
relative to parking at a location without these amenities. The ability to refuel or perform
maintenance on the trucks while meeting the HOS allows drivers to get more out of their
workday.
Better rested drivers: The ability to shower, eat well, and be in a safe environment also
allows drivers to rest more fully. Better-rested drivers are likely to be more attentive and
drive more safely.
Deployment of green technologies: Truck parking facilities can be designed to have auxiliary
power units that feed power to the cab that enable heating and cooling without having to run
the engine. Parking facilities could also have stations that allow for recharging of electric
trucks. All this leads the parking facilities to support the deployment of green technologies in
the truck fleet that reduce emissions of criteria pollutants and greenhouse gasses.
Truck Parking Costs
Previous sections discussed the benefits of providing truck parking. This section discusses the
costs. Capital costs are the one-time expenses incurred to build the project. Operations and
maintenance (O&M) costs should also be included in the analysis, however in a BCA framework
they should be included as a negative benefit, and not added to the capital costs. Some projects
might decrease O&M costs, which would result in a benefit, however most projects that involve
new construction are likely to increase O&M costs, and therefore would be included in a BCA as
reducing the net benefits of the project.
Capital and O&M Costs: The capital costs of creating new truck parking spaces, whether by
constructing a new facility or expanding an existing one, should be estimated with as precise
information as possible, and should consider local factors and project specifics. Engineering
estimates are the best source of cost information, because they consider local material costs,
wages, and constraints. If engineering estimates are not available, planning-level estimates can
also be used. However, care should be taken to ensure they are realistic and representative.
Truck Parking Development Handbook
29
Capital costs include all expenses required to build the project, including project planning,
design, environmental reviews, utility relocation, construction, and transaction costs to secure
financing. Capital costs should not be limited to those for which public funds are sought for the
project.
The USDOT guidance for conducting benefit-cost analyses includes land acquisition costs.
23
These costs will vary widely throughout the U.S. Some municipalities make parcel and property
tax data available, which can help provide estimates of a parcel’s value.
The O&M costs of the parking facility should also be included. O&M costs can be broken down
into costs relating to the operation of the parking facility and costs related to sales activities (gas
and concessions). These include:
Employees.
Utilities.
Maintenance.
Administrative costs.
Consumables.
Economic Development: The private-sector benefits of truck parking projects will, over time,
support economic development, in terms of additional jobs, income, and taxes. The following
types of economic development impacts are typically associated with truck parking projects:
Facility Operations: The expenditures required to run the parking facility will also have
positive economic impacts. These expenditures support jobs involved in the operation and
maintenance of the facility, as well as jobs involved in the supply of products purchased at
the facility such as fuel and food.
Adjacent Development: New truck parking facilities will also attract truck-related businesses
to locate in the surrounding area. A recent study in Little Rock, Arkansas found that land
values are higher closer to truck parking facilities, holding other factors constant, reflecting
increased demand for locating in these areas.
24
Regional Economic Competitiveness: The lower transportation costs, improved reliability,
and other private-sector benefits will lead businesses to be more competitive, do more
business, hire more workers, and contribute to raising the level of economic activity in a
region.

Construction: The expenditures made to build a new parking facility, or expand an existing
one, positively impact the local economy. This supports not just jobs in the construction
sector, but jobs in other sectors that supply goods and services for construction activities.
Economic development impacts can be presented alongside the results of a BCA analysis to tell a
compelling project story, but based on standard practices, should not be included in the BCA
itself. For a broader discussion of the benefits of freight to local communities see the FHWA
Freight and Land Use Handbook.
25
Benefit-Cost Case Studies
Two case studies were developed to demonstrate how to apply the benefit-cost methodologies to
evaluate truck parking projects. These case studies were drawn from two existing studies. The
projects were hypothetical, however, and no new data collection was conducted. These case
studies illustrate how to estimate the benefits of these types of projects and balance needs with
costs. The following is a summary of their context and findings:
Case Study 1: Portland, Oregon: The 2019 Oregon Commercial Truck Parking Study found that
areas in and around Portland, OR have the highest demand for truck parking, leading parking
facilities in these locations to operate at capacity.
26
This case study examines the benefits of a
hypothetical project that increases truck parking capacity on I-84 approaching Portland. This
corridor already has a few parking facilities. They have limited availability, however, and
forecasts show that by 2040 there is likely to be a capacity shortfall of 39 spaces. The project
would also reduce undesignated parking on this corridor, which is significant as the study found
10 sites of undesignated parking nearby. Approximately 95 trucks park at these locations (for 30
minutes or more), for an average of 2.4 hours each. The hypothetical project involves the
construction of a 100-space parking facility that offers amenities to truck drivers. The project is
assumed to have capital costs of $7.5 million and yearly operating costs of $200,000.
A benefit-cost analysis shows that this project would generate significant benefits, yielding a
benefit-cost ratio of 1.8 discounted at three percent and 1.0 discounted at seven percent. As
shown in figure 7, approximately 58 percent of the benefits are expected to come from the
reduction of undesignated parking, and 21 percent come from the reduced need for detours to
find a parking space. The rest of the benefits of the project are expected to come from
improvements in trucking productivity and avoided trucking externalities (e.g., emissions,
roadway crashes, and pavement deterioration).

Case Study 2: Phoenix, Arizona: The 2020 MAG Truck Parking Study identified a large
imbalance of parking demand relative to the supply of spaces in the Tolleson area of Phoenix,
AZ, which is located where I-10 meets the Agua Fria Freeway.
27
This area is home to significant
industrial and commercial activity, making it a major attractor of truck traffic. This creates a
large demand for truck parking, particularly for staging purposes as drivers wait for a delivery or
pickup appointment. There are several truck parking facilities in this area, however, they are
currently operating at capacity. Difficulties finding parking contribute to the high proportion of
undesignated parking observed in the Tolleson area. The MAG Truck Parking Study estimated
that four locations in this area accumulate 71,300 hours of undesignated parking per year, after
expanding the GPS records.
Faced with this need, FHWA analyzed a hypothetical project that repurposes a vacant lot in the
Tolleson area into a low-cost public truck parking facility with the capacity to accommodate 100
trucks. This hypothetical project was assumed to be accompanied by an information campaign
and stricter enforcement to reduce undesignated truck parking. The project was assumed to cost
$3.5 million (including land acquisition and construction costs) and have yearly operations and
maintenance costs of $100,000. While acquiring land in an industrial area such as this one is
typically expensive, the project is expected to generate significantly more in benefits from
improved safety, improved trucking productivity, and avoided externalities.
The project was estimated to have a benefit-cost ratio of 1.2 when discounting at seven percent,
and 2.15 when discounting at three percent. As shown in figure 8, approximately 60 percent of
the benefits would come from safety improvements from reduced undesignated parking.

3. SITING AND DESIGNING TRUCK PARKING FACILITIES
New truck parking facilities will be most effective if they are located where drivers need and
expect to find truck parking. However, communities also need to balance industrial and
transportation land uses with residential, recreational, educational, medical, and other uses.
Proactive planning and requirements for truck parking siting and design can reduce tension
between the goals of supporting quality of life and industry.
SITING TRUCK PARKING FACILITIES
Zoning and developing appropriate locations for truck parking facilities are essential steps for
harmonious coexistence of truck parking and other community uses. This section describes
considerations for siting truck parking as well as land use compatibility concerns.
Freight Intensive Land Use and Truck Parking
Truck drivers make decisions about when and where to park based on many factors and
optimizing the journey between customers is a central consideration. As a result, the highest
truck parking demand in an area is typically located near industrial land uses and along major
truck routes. Just as a commuter stopping for fuel would look for a gas station on their route to
work in favor of introducing a detour, a truck driver would prefer to park along their route or
near their next stop. Truck drivers have additional reasons not to deviate from their planned
route: rural and local roads may have restrictions against large heavy trucks and have narrow
roadways, low bridge clearance, or other elements not designed to accommodate large trucks.
Effective siting for truck parking blends an understanding of driver needs with land use
considerations. While truck intensive land uses may naturally locate near highway interchanges,
agencies should consider access and traffic impact to ensure that traffic generated from the use
will not adversely impact traffic operations in the area.
Lessons from Private Truck Stop Development
Most truck stops provide parking at no charge. A truck stop’s largest revenue source is diesel
fuel, though fuel typically has a low profit margin. Truck stops also sell food, convenience, and
travel items, and many offer truck repair services. A key feature distinguishing truck stops from
Where to start: evaluating your community
Knowing that truck drivers are making decisions based on operational needs, safety, and
security, the following questions can guide exploration of likely high-demand areas:
Where are the existing land uses that attract truck traffic? For example, an industrial
park or a port.
Which highways in your community carry the highest levels of truck traffic?
Where are existing truck parking facilities near or over capacity? Consider that drivers
will easily find and utilize new capacity near places they already search for parking.
Where are commercial and industrial developments expected to occur?
Truck Parking Development Handbook
34
other retail fueling locations is the provision of amenities such as restrooms with driver showers,
laundry facilities, free Wi-Fi, game rooms, and financial services.
To provide amenities and free parking, truck stops must attract a high volume of customers. The
most important consideration in the site selection process for locating a new truck stop travel
center is proximity to major roadway corridors such as a highway, interstate, or turnpike.
Understanding the truck driver’s perspective is paramount to location decisions: most truck
drivers will not venture beyond locations they can see from the mainline highway, especially
when available parking is uncertain.
Warehousing and distribution patterns can also guide planners toward areas of emerging truck
parking demand. Since the rise of e-commerce in the 21
st
Century, changing consumer patterns
and expectations have led to the development of large warehouses and fulfillment centers in
urban areas. The magnitude of this growth is demonstrated in figure 9. These facilities are served
by large trucks as well as smaller trucks and vans. They also generate significant demand for
truck parking due to the staging that occurs while drivers wait to access the facility. Modern
warehousing requirements typically include:
Proximity to urban centers.
Proximity to ports and highways.
Capacity of the highway to support the truck traffic.
Sufficient square footage to support efficient operations.
Adequate land for tractor trailers to park and move goods.
Ideal sites for both truck parking facilities and other industrial uses also have compatible
adjacent land uses. These concerns will be discussed further later in this section. Proactively
zoning and preserving land meeting these criteria to accommodate truck parking will reduce
future conflicts between truck parking and other development types.
Case Studies from Public Sector Siting and Planning
Several truck parking studies led by the public sector have applied industry needs to truck
parking siting exercises. Some studies assessed demand generally, while others examined the
suitability of specific sites. This section describes four case studies and highlights key findings
from each.

Case Study 1: The Mid-America Freight Coalition (MAFC) examined the potential truck
parking availability of vacant urban parcels to reduce the frequency and severity of truck parking
shortages related to staging within the Mid America Association of State Transportation Officials
(MAASTO) region.
28
The study methodology identified parcels and assessed parcel suitability
for truck parking within metropolitan areas of its 10 member States. The MAASTO study used
the National Highway Freight Network (NHFN) to identify truck parking locations for staging
purposes that required access to the metropolitan areas of the region.
29
The methodology
imposed a five-acre threshold to accommodate truck parking and associated infrastructure and
limited potential parking sites to those within 0.25 miles of the identified major road corridor or
on/off ramp. Using satellite imagery researchers identified parcels that were homogenous and
undeveloped. Using filters related to freight volumes, security, parcel ownership/value, and
environment, the process identified 72 potential parcels.
Key Takeaways:
Study focused on the NHFN, limiting evaluation to corridors with high truck traffic.

highways for freight movement. The NHFN is established under 23 U.S.C. 167 to strategically direct Federal
resources and polices toward improved performance of the Network.

Parcels were at least five acres to ensure meaningful new parking would be added.
Sites were within 0.25 miles of a major highway to meet truck driver needs.
Case Study 2: The Illinois Center for Transportation Studies (ICT) explored truck parking in
southern suburbs of Chicago.
30
ICT evaluated policy and design issues related to planning and
developing overnight truck parking facilities. ICT researchers found that access to an arterial
highway was the most important prerequisite to site selection. Adequate or easily-upgraded pre-
existing infrastructure was identified by the authors as a factor that minimizes costs for the
developer and the local or State municipality. Infrastructure prerequisites included roads with
proper width, pavement quality, and vertical clearances of bridges and traffic signals. Greenfield,
adjacent residential uses, farmland, and wetland/floodplain parcels were considered undesirable
for truck parking developments. The researchers also noted that intersection design and signal
phasing may need to be updated to accommodate increased truck traffic.
Key Takeaways:
Access to a major highway was the most important factor identified for site selection.
Brownfield redevelopment was prioritized, and development adjacent to residential or
agricultural uses was discouraged.
Cost can be minimized when existing pavement, bridge, and signal designs already
accommodate truck traffic.
Intersection design and operation may need to be adjusted to accommodate increased truck
volumes.
Case Study 3: The Center for Advanced Infrastructure and Transportation (CAIT) at Rutgers
University also produced a framework for evaluating truck parking locations and capacity
expansion.
31
The study highlighted the need to make truck parking a priority in facility siting
decisions, and compared population density, manufacturing density, warehousing density, and
retail density to truck parking locations. The framework established in the CAIT study focused
on the potential benefits and costs associated with truck parking to evaluate sites in New Jersey
(figure 10). During the examination of specific sites, the researchers found that some factors
were more impactful than others. For example, noise pollution had a greater cost than air
pollution based on impacts to property values. Of financial impacts, sales tax had the greatest
potential benefit.

Case Study 4: Florida DOT (FDOT) District 6 recently identified locations for truck parking in
Miami-Dade County.
32
An initial study by the county in 2012 identified 21 vacant or FDOT
owned parcels greater than 9.5 acres in size and within 1 mile of a highway interchange. A
screening process reduced the number of sites to 12. Incompatible development and traffic
studies reduced the total feasible sites to nine. In 2018, a second study effort examined 14
potential truck parking sites: seven were found to have fatal flaws and two others had potential
contamination issues. Five remaining sites were evaluated by engineering feasibility and
stakeholder support, resulting in four more sites being removed. The remaining site received
support from the Miami-Dade Transportation Planning Organization (TPO) Freight
Transportation Advisory Committee and as of 2018 was being planned under a Public-Private
Partnership (P3) Concessionaire Agreement Location in a potential rapid transit corridor was
identified as a project risk. In the most recent effort FDOT District 6 identified an additional 19

the focus of additional analysis.
Key Takeaways:
The study focused on vacant and publicly-owned parcels to reduce future risk associated with
right-of-way acquisition.
Parcels were over 9.5 acres and within 1 mile of a highway interchange to ensure reasonable
use as a truck parking area.
Multiple stages of screening allowed high-level feasibility to be determined prior to investing
in engineering, stakeholder engagement, and environmental study.
Land Use Compatibility and Community Concerns
Community opposition to truck parking facilities can stem from concerns about incompatibility,
especially between freight and residential land uses. Communities throughout the Nation are
experiencing land use conflicts as populations spread out, industrial developments become more
intense, and as distribution and fulfillment centers strive to locate near population centers.
Recognizing the interdependency between economic vitality, quality of life, and goods
movement can begin to alleviate opposition. The American Planning Association (APA)
encapsulates the balance between supporting freight industries and promoting sustainable
communities in its Policy Guide on Freight.
33
Similarly, the FHWA Freight and Land Use
Handbook (Publication FHWA-HOP-12-006) encourages practitioners to conduct land use and
transportation planning in a complementary way.
34
Appropriately-located truck parking facilities can serve community needs: they can improve
roadway safety, increase economic competitiveness of local freight intensive businesses, and
contribute to local tax revenue. Case studies of successful developments are included in the final
sections of this Handbook. However, siting of truck parking facilities should be done in
consideration of the potential externalities such as:
Roadway impacts from increased truck traffic.
Nighttime light pollution.
Noise and air pollution from idling trucks.
Trash and dumping at the site.
Perceptions of security and crime issues.
Equity impacts to neighborhoods adjacent to freight-intensive land uses.

39
These concerns can be mitigated through thoughtful siting and design of truck parking facilities,
and design will be discussed in greater detail in the following section. Truck parking siting
considerations mirror other commercial and industrial siting considerations:
Avoid sites near residential land uses, schools, and other community amenities where people
may be exposed to air, noise, and light pollution. Site design and buffering can be used to
further mitigate these issues.
Prioritize locations near major highways with suitable access to reduce traffic impacts and
increase trucking efficiency.
Evaluate how siting choices will positively or negatively impact the equitable distribution of
transportation externalities in your community.
Assess the ability of access roadways to accommodate large trucks and identify necessary
changes for safe operation. For example, intersection and traffic control may need to be
improved to support truck traffic.
Co-locate with existing industrial developments to better serve the freight industry and
reduce community impacts.
Choose sites with sufficient space and utilities for restrooms and trash service.
Consider how truck traffic may impact other critical transportation services, such as
ambulances or firetrucks.
Siting that results in separation of incompatible uses is effective at mitigating concerns.
However, not all communities will reasonably be able to separate uses. The design of truck
parking facilities is also critical for creating a safe, secure environment for both truck drivers and
community members.
DESIGNING TRUCK PARKING FACILITIES
The following section presents geometric design considerations for creating truck parking
facilities. Most of today’s modern tractor-semitrailer combinations moving in interstate
commerce include a 53-foot semitrailer. This so-called interstate semitrailer combination
depicted in figure 11, is also referenced as a wheelbase 67 (WB-67) design vehicle. Key values
used for the WB-67 design vehicle include a trailer length of 53 feet and a trailer with tractor
width of 8.5 feet (table 5). AASHTO’s A Policy for the Geometric Design of Highways and
Streets (the “Green Book”) establishes standards governing the design of highways and freeways
in the United States (23 CFR 625.4(a)(1)). The 2018 edition of the Green Book states:
The WB-67 truck should generally be the minimum size design vehicle considered for
intersections of freeway ramp terminals with arterial crossroads and for other intersections on
State highways and industrialized streets that carry high volumes of truck traffic or that provide
local access for large trucks, or both.

It should be noted that when planning a truck parking facility, planners and engineers should
assess whether there are any oversize/overweight considerations in the surrounding area. For
example, modular home and/or heavy equipment manufactures often move over-dimension
cargoes that may require considerations for parking space beyond standard design vehicle
requirements. Nearby industrial uses as well as common through traffic should be considered in
an assessment.
Geometric Considerations for Truck Parking Design
There are several important geometric attributes to consider when designing a truck parking
facility, including:
36
1. Turning radius.
2. Parking stall design.
3. Parking slot type.
36
Another useful reference for understanding truck design attributes is NCHRP Report 505: Review of Truck
Characteristics as Factors in Roadway Design.

4. Swept path.
5. Slot density.
6. Access, layout, and circulation.
Turning Radius
The turning diameter of a vehicle refers to the minimum diameter (or "width") of available space
required for that vehicle to make a circular turn such as a U-turn. The term thus refers to a
theoretical minimal circle in which the design vehicle can be turned around. The turning metrics
for the WB-67 truck are shown in figure 12.

For the remainder of this section, the CHDM is referenced. The CHDM describes design
standards for large trucks and is accessible online.
37
The CHDM covers a wide range of
technical issues related to truck parking facility design, making it a valuable reference for other
jurisdictions. Its provisions are widely accepted and provide a sound basis for the design of safe,
practical, and efficient roadways and associated facilities. Use of the CHDM is not required by
Federal law or regulations.
Parking Stall Design
The CHDM provides information on laying out vehicle parking areas and dimensions for vehicle
parking stalls (table 6). The specified stall width for “long vehicles,” like semi-trailer trucks, is
12 feet. A space of 8 feet is suggested between each stall to allow safe foot traffic between
parked vehicles. These dimensions allow room for safe vehicle maneuvering where other drivers
or pedestrians may be present while still providing efficient parking density.
Table 6. Vehicle parking stall standard dimensions (feet).
Vehicle Type Minimum Stall Width Aisle Width Aisle Location

2 Autos 9 5 Between stalls
1 Van 9 8 Passenger side
1 Van/1 Auto 9 8 Between stalls
1 Long Vehicle 12 8 Passenger side
2 Long Vehicles 12 8 Between stalls
(Source: California Highway Design Manual, 2020.)
Parking Slot Type
The two main types of parking slots used in truck parking areas are straight back-in (SBI) slots
and herringbone drive-through (HDT) slots.
SBI slots achieve the highest parking density with many maritime and intermodal facilities using
this configuration with 10-foot-wide slots. Factory loading docks, warehouses, retail facilities,
and distribution centers also use this configuration with slots ranging from 15 to 20 feet wide.
Many truck stops also use SBI slots ranging from 10 to 12 feet wide. While truckers are adept at
backing into and pulling out of such spaces, the sometimes-narrow parking space can lead to
damaged mirrors, broken lights and other vehicle damage as vehicles come and go in busy lots.
SBI slots do provide the highest parking density and offer the lowest per-slot development cost.
Driver surveys routinely show a preference for HDT slots. The slots are at an acute angle to the
access aisle, typically 45
o
. The truck enters from one end of the slot and departs through the far
end, never having to back up. This configuration is easier for the drivers and reduces the
incidence of collisions between moving and parked trucks. Highway rest areas use HDT slots for
long vehicles, including trucks, buses, and long recreational vehicles. HDT parking density is
37
California Highway Design Manual, 2020. https://dot.ca.gov/-/media/dot-
media/programs/design/documents/hdm-complete-12312020a11y.pdf.
Truck Parking Development Handbook
43
about 50 percent of SBI parking density, and per-slot development costs are proportionally
higher. However, the difference in development cost is generally outweighed by the geometric
benefits to safety and truck operating efficiency.
Another consideration is the driver’s personal safety. Truck drivers in interstate commerce are
required by Federal law to conduct daily vehicle inspections (49 CFR 396.11(a)). Drivers
frequently use truck stops and rest stops to inspect loads and vehicles. A driver will walk around
the vehicle to check tires, lights, mirrors and other safety equipment, load security, and generally
ensure no damage has occurred to the vehicle or load. SBI slots limit driver visibility at the rear
of the parking slot, potentially creating a hazard for drivers on foot.
38
By contrast, the HDT slot
allows the driver to readily see the entire parking slot and the edges of adjacent slots.
Swept Path
As trucks maneuver into and out of parking slots, their vehicles sweep out a path. As the turning
angle sharpens, the swept path is wider. Figure 13 shows the paths swept for the design Vehicle
as it enters or leaves a herringbone parking block of angle = 60°, assuming a slot width of
20 feet. The dimension of 62 feet is sufficient to allow a truck to enter or leave a slot without its
swept path hitting an adjacent vehicle.
38
Refer to appendix A for guidance on calculating the geometric requirements for HDT parking slots.
Truck Parking Development Handbook
44

(Source: California Statewide Truck Parking Study, 2021.)
Slot Density
Slot density refers to the number of truck parking slots that can be configured per acre. Table 7
shows the relationship between stall dimensions and overall truck parking slot density for a range
of different slot configurations, assuming a row length of 40 single-truck parking slots. Using the
WB-67 standard, with 74-foot trucks in 20-foot slots at a 45° angle, ideal parking density is
13.5 trucks per acre. Changing the herringbone angle over a range of 30° to 50° has only a
modest impact on density. A 45° herringbone angle is recommended unless the overall site area
would be more effectively used at a different angle. The final row in the table shows the density
for SBI slots 12 feet wide, like the arrangement commonly used in commercial truck stops. This
configuration has about twice the density of the 74-foot/45° herringbone but is not optimal for
truck parking areas.

Access, Layout, and Circulation
Access to truck parking areas should be clearly marked in advance and designed to ensure safe
operations. Truck parking areas can be designed for access via:
Freeway or Highway Ramp: Medium-speed approach with limited turning. The ability to add
new entry and exit ramps on an existing freeway depends on the proximity of existing
interchanges and arterial crossings. Establishing freeway connections for a truck parking area
in an urban or suburban setting will typically constrain facility size. Even in exurban settings,
the spacing of arterial road crossings, whether at an interchange or grade-separated, may
limit the size of a freeway truck parking area. Freeway truck parking areas will most likely
be limited to interurban sites.
Arterial Road “Curb Cut:” Low-speed approach, typically through a sharp or right-angle
turn on entry and/or exit. Urban truck parking areas may be viable on areas that have limited
utility for urban development, such as spaces under highway or rail viaducts.
Because truck drivers leave their rigs to use service facilities in the truck parking area, it is
advisable to include a clearly-striped walkway along the noses of the tractors. The walkway
should be a minimum of 6 feet wide, allowing a pedestrian to dodge a hazard while staying
within the striped area.
HDT parking rows are usually laid out in pairs to conserve circulation space. There are two ways
for trucks to circulate through such paired rows. Figure 14 shows trucks arriving from outside the
row pair and departing along a shared lane between the rows. Figure 15 shows the reverse, with
trucks arriving along a shared access lane and departing outside the row pair. Both layouts show
pedestrian walkways along the fronts of the parking slots. Both layouts are viable, providing
alternative approaches to site utilization and pedestrian circulation.

Truck Parking Development Handbook
47
Pedestrian circulation should allow for safe, accessible, and direct navigation between parking
stalls and on-site amenities. Additionally, while access to adjacent sites is not always
appropriate, consider whether drivers are likely to walk to nearby sites for goods, services, or
exercise. Pedestrian safety can be improved by placing emergency call boxes throughout the site,
using convex mirrors to reduce blind corners, and using appropriate lighting. Site layouts that
reduce distance between parking and restrooms can reduce waste management issues.
Truck Parking Area Safety and Security
Since Congress passed Jason’s Law, concerns over adequate and safe truck parking have
intensified, including what constitutes “safe” truck parking. Many statewide truck parking plans
and studies have identified trucks parking on highway shoulders, on entrance/exit ramps, or in
undesignated lots as “unsafe,” but few studies clearly define what makes a “safe” parking area.
39
Common themes from these studies suggest safe restrooms, adequate lighting, and security
features such as fencing, cameras or on-site personnel are necessary features for safe parking
environments. Figure 16 shows commonly-identified elements that define safe parking areas.
Figure 16. Graphic. Common features of safe truck parking.
(Source: FHWA, 2021.)
The National Coalition on Truck Parking: Activity Report 2015-2016 notes the importance of
involving local police departments as stakeholders due to local public perception of truck
parking as an issue/problem due to fear of criminal activity. Local police can also serve as a
point of contact for highlighting issues related to driver safety and cargo theft.
40
Cargo theft is
yet another issue across the U.S. which is heightened by the lack of secure parking facilities: In
2017, 75 percent of thefts occurred within unsecured parking areas, such as public parking, truck
stops, and drop lots.

The Illuminating Engineering Society (IES) offers voluntary design guidance for parking lot
illumination that involves interpretation of the overall lighting conditions and use of the site.
42
The following lighting is recommended:
Minimum average horizontal illuminance of 0.5 foot-candle to provide essential safety.
Maximum ratio of maximum/minimum illuminance of 3:1 to prevent dark spots.
Full upward cutoff to prevent sky glow and light pollution.
Full lateral cutoff at the edge of the site to prevent glare and light pollution in adjacent sites.
Color temperature of 4000K to 5000K to support accurate color differentiation.
Lighting designed to these standards will allow drivers to see where they are going and allow
pedestrians to see moving and stationary obstacles, while minimizing external impacts.
Directional lighting should also be used at facilities in proximity to residential land uses, so that
it does negatively impact nearby neighborhoods. This is discussed in greater detail later in this
chapter.
Security
Control of truck access to the truck parking area is a major planning and design consideration
needed to implement secure environments where truck drivers can rest safely in accordance with
the goals of Jason’s Law. The safety, security, and utility of truck parking areas are maximized if
access is limited to truckers who need them. Allowing passenger vehicles, buses, and
recreational vehicles into truck parking areas increases the risk of pedestrian and vehicular
accidents as well as theft and other criminal activity.
Truck parking planning and design should reflect intended uses of the facility (e.g., whether it is
for short-term staging versus overnight parking for rest). Parking areas near a major logistics
hub, such as a marine terminal, rail yard, or distribution complex, may tempt drivers to use the
facility for short-term storage of trailers. Allowing trailer parking may limit utility facility as a
rest or holding area and may add security risks. Prohibiting trailer parking requires detection and
enforcement.
Control options include:
Soft Control: Access control can be achieved with a combination of the following: 1) an
ordinance limiting truck parking area access; 2) signage advising approaching vehicles of
access limitations; and 3) enforcement of the ordinance by citations or other actions. Such
soft control of access would not require major infrastructure and would not affect the design
of the site.
Hard Control: Access control also can be achieved by installing an access gateway that:
1) can only be opened by truckers that are permitted to use the facility, and 2) can be opened
by any trucker needing to use the facility. The challenge is establishing a trucker access

research-report-lighting-for-parking-facilities/.
Truck Parking Development Handbook
49
system that limits access without excluding those who need it. Ideally, the access system
would need to be usable by any trucker in the country, making use of any State- or region-
based truck identification, such as a radio-frequency toll tag, impractical. Charging for access
may be impractical or contrary to State or Federal regulations. Using vehicle front axle
weight would not allow differentiation between truck tractors and laden intercity buses. In
summary, hard control of access is probably not practicable.
Control Recording: Soft access control can be augmented by capturing the image and
license tag of any vehicle attempting to enter the truck parking area. This would require
installation of imaging and recording equipment, activated by a ground loop, weight sensor,
or another instrument. Having a record of entries and exits would assist in access
enforcement.
Human Trafficking Prevention Strategies
Safe, secure truck parking facility design is also a tool to prevent or halt human trafficking. The
trucking industry is on the front lines in the fight against human trafficking, serving as the eyes
and ears of America’s roads. Groups such as the National Association of Truck Stop Operators
(NATSO), Truckers Against Trafficking, and the Owner-Operator Independent Driver
Association (OOIDA) are active in creating and disseminating resources.
Table 8 summarizes human trafficking prevention strategies from a wide range of organizations,
associations, and companies that are working closely to identify and combat human trafficking
along truck stops and rest areas.

Truck drivers are the eyes and the ears of the highway, making them essential in the fight against
human trafficking. Employees at all levels, from those at the plazas to the actual truck drivers,
and local law enforcement personnel should be trained to work together to combat human
trafficking at truck parking areas.
Designing Truck Parking Amenities
Truck parking areas should be equipped with lighting, toilet facilities, communications services,
and open space. Additional amenities may also be provided depending on truck parking needs at
a given location and whether existing private truck stops exist to meet these needs. For example,
food, laundry, and shower facilities are commonly needed by long-haul drivers, but may be cost-
prohibitive to provide without a compelling gap in available services.
Restrooms
Given the potential of truck parking areas to be isolated, the personal security of facility users
should be of paramount importance in restroom or water closet design. Truck parking areas
should have toilet facilities compliant with local, State, and Federal regulations. Where toilet
Truck Parking Development Handbook
51
facilities are provided, they must comply with the 2010 Americans with Disabilities Act (ADA)
Standards for Accessible Design (for State and local governments, see 28 CFR 35.151 and the
2004 ADA Accessibility Guidelines (ADAAG) at appendices B and D to 36 CFR part 1191; for
public accommodations and commercial facilities, see 28 CFR part 36, subpart D, and the 2004
ADAAG at appendices B and D to 36 CFR part 1191). Figure 17 shows the components of an
accessible single user toilet room along with citations to the applicable provisions of the 2004
ADAAG. There is no standard minimum area for all toilet room configurations, and required
space depends on the configuration and features of the toilet room. A minimum of 40 square feet
of building area should be budgeted for each single use toilet room.
Figure 17. Diagram. Components of an accessible single user toilet room.
(Source: Guide to the ADA Accessibility Standards, U.S. Access Board, 2021.)
Truck parking area restrooms should be in fixed, permanent structures, should be properly
plumbed for water and for effluent discharge to an enclosed sewer system, and should be
ventilated and climate-controlled for the comfort of the users. Restroom facilities should be sized
to accommodate the expected number of visitors based on the number of parking slots in the
truck parking area and passenger vehicle parking area. One way to determine the proper size for
restroom facilities is based on the Occupational Safety and Health Administration’s requirement
governing the minimum number of water closets, or bathroom stalls, for workplaces (see 29 CFR
Truck Parking Development Handbook
52
1910.141(c)(1)(i)). In this example, the number of parking slots is substituted for the number of
employees that establishes the minimum number of required bathroom stalls, as summarized in

Communications Services
Access to wireless communications services, including both Wi-Fi and cellular service, is an
important amenity for truck parking facilities. Communications can be used for commercial or
personal purposes and need to be secure to prevent attacks on increasingly complex and
technologically advanced transportation equipment. In rural areas with otherwise poor services,
provision of Wi-Fi also improves safety. To provide reliable cellular service, truck parking areas
should be sited close enough to cellular communications antennae to support a minimum
sustained signal strength of -85 dBA, approximately equivalent to “three bars” of signal strength
on most phones. As most smartphones rely on 4G and 5G protocols, these protocols should be
available at the site.
Open Space
It is recommended that truck parking areas provide open space where drivers can exercise. Truck
drivers may also want to take meal breaks at truck parking areas, so the provision of outdoor
picnic tables where drivers can eat and gather outside the confines of their trucks is also
encouraged. Additionally, truck drivers may be accompanied by pets or service animals, and
designated pet relief areas are recommended to facilitate exercise as well as waste management.
As an element of good urban planning, boundary landscaping should provide a visual and noise
buffer between freight intensive land uses including truck parking and adjacent residential or
commercial sites. Additional detail on land use practices is provided in the Siting Truck Parking
Facilitiessection of this Handbook.
Mitigating Impacts on Adjacent Land Uses
When planning or developing a truck parking project, the surrounding community may have a
negative perception of the trucking industry and truck parking. Some of the potential concerns
discussed earlier in this Handbook include increased truck traffic, light pollution, noise and air
pollution, trash and dumping, and perceptions that truck parking facilities attract crime.
Practitioners should understand and be able to communicate the positive benefits associated with
Truck Parking Development Handbook
53
more efficient trucking operations and safe, secure parking so that residents can weigh both
positive and negative impacts of potential projects.
Designing facilities to manage trash and waste effectively, to fit the community character, and to
provide well-lit, secure parking can mitigate these concerns. In general, mitigation approaches
for site expansions should be like new sites; however, local requirements for new developments,
redevelopments, and site improvements may differ. Some specific strategies that can be to
incorporated into site design, as permitted under local requirements, include:
Comparing impacts of multiple uses at a site. A single industrial site may incorporate
several functions. For example, a site may include a warehouse, a laydown area, equipment
storage, and truck parking. The relative impacts of each of these uses should be compared,
and those uses with the lowest impacts should be located nearest sensitive adjacent land uses.
Buffering impacts. Distance, trees, or physical barriers may be necessary to separate the
light, noise, and air pollution generated at a truck parking facility. These buffers can also
reinforce existing community character, such as utilizing native foliage between parking and
adjacent uses.
Using directional lighting. Lighting is an essential element of any truck parking facility to
ensure safety and security. Directional lighting illuminates the parking area while reducing
light pollution for the surrounding community. The International Dark-Sky Association has
published resources to prevent light pollution, including common practices, ordinances, and
other guides.
43
Providing adequate waste service. Littering is a common community concern related to
truck parking facilities. Sites should be designed to include sufficient trash volume and
frequent enough service to prevent littering. Additionally, providing restroom facilities
reduces waste concerns. If a site cannot accommodate flush toilets, portable toilets are
recommended to reduce human waste issues.
Prioritizing access points to and from major roadways. Truck traffic impacts will be
reduced when truck drivers need to make fewer turns and travel a shorter distance to access
parking facilities. Primary entrance and exit points should efficiently move trucks between
thoroughfares and the site while minimizing travel on local streets.
Figure 18 demonstrates how these mitigations can be applied. The FHWA Freight and Land Use
Handbook includes additional considerations related to freight intensive land uses.

Designing for Future Freight Vehicles
Two emerging trends in freight vehicle technology may lead to questions about the future of
truck parking facilities: electric vehicles (EVs) and connected and autonomous vehicles (CAVs).
Truck parking sites will continue to serve a significant role in trucking and transportation
logistics as these vehicle technologies evolve. As EVs are adopted in more contexts, the presence
of powerful charging infrastructure at truck parking sites will become a critical asset. Parking for
rest breaks or other purposes presents an ideal opportunity for charging infrastructure because
drivers are already planning to remain at the site for an extended period of time. When
incorporating EV infrastructure considerations into site design, consider whether utilities to
support charging exist or could be added or upgraded. Additionally, determining the necessary
space at each stall to accommodate charging infrastructure may be helpful for determining the
layout and overall footprint of parking to reduce cost of future improvements. The Infrastructure
Investment and Jobs Act (Public Law 117-58, also known as the “Bipartisan Infrastructure Law)
included funding for EV infrastructure. This Federal assistance may help offset costs associated
with providing charging infrastructure.
The future of logistical and regulatory requirements related to CAV operation remain unknown.
However, it is reasonable to assume that CAVs will remain staffed with a driver or operator for
the foreseeable future to manage cargo as well as the vehicle, and these operators will require
breaks to rest and meet basic needs. Additionally, the need to stage prior to arrival at a customer
or gateway would remain largely unchanged in a CAV environment. Depending on location and
size, rest areas may also have the potential to become transition zones where cargo and/or
vehicles shift from autonomous operation to driver-led operation. This transition may be
necessary to navigate more complex environments or meet future regulatory requirements. While
the precise future of trucking logistics in a CAV environment will evolve over time, the need for
dedicated truck parking and staging locations is anticipated to remain.

4. ENCOURAGING AND REQUIRING TRUCK PARKING
Previous sections have discussed the role of trucking and truck parking on our economy and
quality of life and the truck parking shortage. This section provides resources for communities to
consider when updating land use and zoning policies to address current and future parking needs.
IMPROVING LAND USE AND ZONING POLICIES
When land use and zoning decisions allow for new commercial/industrial development, but do
not account for the increased demands for truck parking, the costs for future mitigation are often
passed on to the local jurisdiction. These costs include the cost of providing truck parking and
costs associated with safety, congestion, and community disruption. A common reaction is to
pass ordinances restricting truck parking, which redistributes the need to another area in the
community or a nearby community.
Incorporating Truck Parking into Traffic Impact Assessments
Counties, cities, and municipalities across the Nation already develop traffic impact assessments
and review site plans for new developments. However, these processes do not always consider
the specific transportation and truck parking needs generated by freight activity. Traffic impact
assessment processes should be reviewed to include anticipated truck volumes at a site and the
impacts of staging near the site. Truck parking demand generated farther from the site should
also be evaluated. These estimates can then be used to evaluate development of parking or
contributions to pooled parking.
The FHWA Truck Parking Demand Estimation Tool can be used to approximate the relationship
between the number of daily truck trips and parking required within various distances of the site.
The distance bands included in the tool are based on available datasets from communities across
the country, but every community is different. Estimates from the tool should be refined based
on your community and input from industry. For example, the estimation tool may predict a
given number of trucks parking within 20 miles of the site. However, if your community has a
rest area 30 miles from the site, truck drivers may park there when spaces are available.
Understanding the directionality of travel in your community may also impact adjustments to
estimates of off-site parking locations. Drivers will be more willing to park farther away if a
parking facility is on their route compared to a detour.
Local data and observations may supplement or replace estimates from the truck parking
estimation tool. For example, the Winston-Salem study highlighted earlier in this Handbook
established estimates based on facility type, employment, square footage, and number of truck
bays in that community. Consult with partner planning organizations in your region and State to
verify whether additional information is available to support traffic impact analyses.
Revising Planning Ordinances and Policies
Communities balance many priorities when developing land use policies, including safety,
quality of life, economic competitiveness, and environmental quality. These values are
important, but they can be undermined when truck parking is not proactively accommodated.
Truck Parking Development Handbook
58
Consider whether and where compromise can be achieved through project design and mitigation
of the underlying community concerns that initially led to restrictions.
Local ordinances routinely set employee and customer parking requirements for developments;
however, on-site truck parking and staging areas are rarely required. In 2017, the Township of
Upper Macungie, Pennsylvania, in the Lehigh Valley became a notable exception to this rule.
The Township passed a new zoning requirement that requires one off-street truck parking space
for every loading dock at a new warehouse or distribution facility.
45
The new zoning regulations
also mandate one truck staging space (with 10-feet x 80-feet dimensions) for every two loading
spaces at a distribution or warehouse facility.
46
Further, the new requirements specified that
applicants (developers) must present evidence that parking will be adequate to accommodate
expected demand. The language is integrated into the Township’s zoning code, which applies to
the passenger parking requirements for employees and visitors/customers of various land uses.
Each community documents its parking and development requirements uniquely. This Handbook
provides the following suggestions that agencies may consider.
Requiring Truck Parking
The following options demonstrate how parking requirements can be based upon loading docks,
building area, or employees:
Option based on loading docks: One 10-foot by 80-foot (10' x 80') parking space for truck
staging for every two (2) loading docks. Parking shall be maintained and available for truck
parking prior to or after a scheduled delivery or pickup.
Option based on building square footage: One 10-foot by 80-foot (10’ x 80’) parking
space for truck staging for the following building areas:

Additional parking or storage needed for maximum number of vehicles stored, displayed, or
based at the lot at any point in time shall not be counted towards the above required parking.
Truck Parking Development Handbook

Ensuring Quality of Parking
The following options demonstrate how to require a standard of quality for parking:
Each off-street loading space shall have a minimum size based on the largest vehicle
intended:
o Tractor-trailer: 10 feet by 80 feet.
o Trucks other than tractor-trailers, pickups, or vans: 10 feet by 25 feet.
o Pickup truck or van: 9 feet by 18 feet.
Each space shall have sufficient maneuvering room to avoid conflicts with parking and
traffic movements within and outside of the lot. No facility shall be designed or used in such
a manner that it threatens a safety hazard, public nuisance, or a serious impediment to traffic
off the lot.
Each space and the needed maneuvering room shall be located entirely on the lot being
served and be located outside of required buffer areas, paved area setbacks and street rights-
of-way.
An appropriate means of access to a street shall be provided.
Paving, grading, drainage, and lighting standards apply to loading areas.
Parking spaces shall be reserved for truck parking and shall not be utilized for storage or
other use.
Allowing Exceptions to Parking Requirements
The following language demonstrates options for allowing exceptions to parking requirements:
To prove that fewer parking spaces are needed, the applicant shall provide existing and
projected employment, customer, resident, or other relevant data. Such data may include a
study of parking at similar developments during peak periods of use.
An applicant may seek to prove that parking permanently shared with another use or another
lot with shared internal access will reduce the total amount of parking needed because the
uses have different peak times of parking need or overlapping customers.
Parking areas for trucks may be shared between adjacent business. An industrial
development with multiple businesses may provide a consolidated parking area for truck
staging and parking serving all uses.
If this Section permits a reduction, the reservation of areas for use in future parking may be
required permanently or for a specified number of years:
o Reservations should be legally documented, such as in a binding deed restriction.
o Plans should be submitted showing where and how additional parking could be
accomplished.
Truck Parking Development Handbook
61
o Such additional parking shall be required to be provided within one year by the owner of
the lot at that time after notification that such parking has become needed. Such
determination shall be based upon an on-site review on least three different days.
CASE STUDIES OF SUCCESSFUL LOCAL TRUCK PARKING DEVELOPMENTS
On-Site Truck Parking at Industrial Uses
Proactively integrating truck parking needs into the planning process (e.g., requiring shippers
and receivers to provide onsite parking or contribute their fair share to the cost of a common
parking area) will help meet the parking demand while also helping to spread the costs of
providing truck parking. A requirement for new industrial developments to provide on-site truck
parking would be like employee and customer parking requirements that are generally included
in zoning ordinances.
Shippers and receivers can also benefit from providing on-site parking. Economic growth
increases the demand for trucking. When capacity of available trucking services is tight, truckers
can afford to be selective, and there can be strong competition to book available trucks. “Even in
a bull market, for carriers to capitalize on earnings from elevated rates, they still need to move
new freight as fast and as efficiently as possible.”
47
Businesses that offer truck parking and
associated amenities available to drivers, whether on property or in a shared staging lot nearby,
become “shippers of choice,” greatly increasing their ability to have their load requests accepted.
Table 13 summarizes the benefits of implementing on-site parking as well as potential barriers to
implementation.

Town of Mount Olive and the Mt. Olive Pickle Company
48
An example of a successful P3 is the recent efforts of the Town of Mount Olive and the
Mt. Olive Pickle Company to address truck traffic and parking issues in the town.
The Town of Mount Olive is in Duplin and Wayne counties of North Carolina and had a
population of roughly 5,000 in 2017.
49
The town is served by a network of highways with
U.S. Highway 117 and NC Highway 55, linking the town to Interstate 40 and the North Carolina
Eastern Region Global TransPark. A large local employer in town is the Mt. Olive Pickle
Company, Inc.
Approximately 50,000 tractor-trailer trucks service the pickle company warehouses and its
distribution center each year. This created safety and congestion issues with the high volume of
heavy truck traffic in downtown and residential areas. Insufficient turning radii on streets turning
off the main thoroughfare to the pickle company warehouse and distribution centers often
resulted in damage to infrastructure. Lack of wayfinding also led to some drivers becoming lost
on local streets, and some of their maneuvers have led to downed utility poles, broken fire
hydrants, and destroyed signs.
A lack of a staging area for trucks also has resulted in trucks having to park in shopping centers
to stage for picking up and delivering to the pickle company and/or for drivers to adhere to HOS
regulations. Increasingly, the shopping centers have been moving towards banning the parking of
commercial vehicles on their property due to liability, property damage, and litter issues, further
aggravating the truck issue.
The Town and the Mt. Olive Pickle Company have taken measures over the years to address the
increasing truck traffic in the Town. The Town erected several way-finding signs to direct trucks
to and from the pickle company to help truck drivers from getting lost and the company provided
detailed directions for truck drivers and a video of the routes to take to arrive at the facilities
without getting lost on their company website. Given the volume of truck traffic servicing the
company, these measures could only do so much to alleviate the problem. Therefore, the Town
of Mount Olive, with the support of the Mt. Olive Pickle Company, approached North Carolina
Department of Transportation to build a road off N.C. Highway 55 East over to Talton Avenue to
take the truck load off the main thoroughfare, Breazeale Avenue.
The pickle company also is constructing a staging area located on Talton Drive adjacent to the
new road that will handle up to 60 trucks at one time with included weight scales, restrooms, and
refrigeration hookups at the site. All the information about the new route has been forwarded to
the county to get an official address assigned for the new road and to have it added to GPS
systems to help truckers navigate when coming to Mount Olive and the pickle plant.
The cost of the new road and staging area is reported to be approximately $3 million. The new
road and staging area will help eliminate much of the heavy truck traffic on Breazeale Avenue,

Church Street, and Park Avenue, reduce truck incursions into residential areas, and allow trucks
to stage on the company property rather than along roads or in retail shopping areas in town. The
new onsite facilities will also improve conditions for drivers by reducing stress in parking and
staging and provides amenities for their comfort. The company believes that the staging area and
amenities will increase efficiency of its operations, make the facility more attractive to trucking
companies to service, and allow the company to be a good corporate citizen to the Town of
Mount Olive.
Shared Truck Parking Facilities
As many States seek to address their truck parking shortages, shared parking facilities provide an
opportunity to leverage partnerships to meet truck parking demand. Partnerships can exist
between private entities, between public entities, and between public and private entities.
Additionally, collaboration between the public and private sectors may illuminate opportunities
to provide additional parking without resulting in a formal P3.
Collaborations have capitalized on available, underutilized land to fill the truck parking gap in
several localities. Many of these shared facilities are at ports, but shared lots have been
introduced at industrial parks, airports, and park-and-ride lots. The design of existing facilities
should be carefully reviewed before repurposing for truck parking because pavement and access
at shopping malls and other large sites may not be designed to support heavy weights. By
utilizing shared parking facilities, cities can capitalize on underutilized space to provide safe and
convenient parking. Private property owners may be able to monetize underutilized space: the
Washington State Joint Transportation Committee Truck Parking Action Plan recommended
promoting participation in parking reservation programs facilitated by mobile applications.
50
These applications create a financial incentive to offer use of parking spaces for a fee, offsetting
additional maintenance costs from parked trucks.
Recommendations from statewide freight plans and other State initiatives, such as the ones listed
in table 14, introduce the value and strategies to develop, fund, and maintain shared facilities.

)
While the Statewide plans provide the framework and vision for shared facilities, several
localities have already developed and implemented these shared facilities to provide safe parking
for drivers:
The Oakland Maritime Support Services (OMSS) Center at the Port of Oakland: When the
City of Oakland acquired a portion of an Army base for development in support of port
operations, 15 acres were set aside for truck parking and related services at the urging of a
coalition of drayage carriers and local residents interested in removing parked trucks from
neighborhood streets. A private enterprise leased the property at fair market value and
developed a truck parking facility adjacent to the Port called the OMSS Center. Later, the
parking area was expanded with support from a $5 million grant from the Alameda County
Transportation Commission. The center serves as a service destination for trucks at the Port
of Oakland with several amenities, including biodiesel and liquefied natural gas (LNG) truck
fuel, a truck wash, maintenance and repair, and a truck scale and cargo weighing stations.
The private owner charges fees to generate revenue to cover the cost of capital improvements
and ongoing maintenance and operations. The OMSS gets trucks out of their neighborhoods
and into designated facilities to the benefit of their community and the drivers.
54
Port of Seattle: In 2009, the Port of Seattle created a nearly 2-acre truck parking area with
more than 100 truck parking spaces.
One of the goals was to encourage truckers to park in the
secured, free facility rather than using off-street parking in the local neighborhoods. Trucks

are allowed to park for a maximum of 14 days. The Port is now considering development of a
10-acre site with the potential for 200 spaces.
55
Miami International Airport Overnight Truck Parking Lot: The Miami International Airport
in Florida has an overnight parking lot with 20 truck parking spaces. The total lot is 2.5 acres
and has no amenities.
56
Port of Brownsville: The Port of Brownsville, TX developed staging parking inside its gates
to meet the needs of its tenants, especially exporters to Mexico. The Port funded this
improvement by increasing its gate fee by $3.00 to offset operations and maintenance costs.
Port staff were interviewed during the development of the Rio Grande Valley Freight and
Trade Transportation Plan. Staff commented that using the available parcel for truck parking
would facilitate trade in the near term while not prohibiting future industrial development at
the site as land at the Port becomes sparse.
Texas-Mexico International Bridges: Several international bridge operators on the Texas-
Mexico border have developed truck staging lots near bridges to accommodate the export
process. Drivers must wait for Mexican customs paperwork to clear prior to approaching the
southbound bridge, and drivers cannot always wait at the shipper’s site for this to occur.
These facilities can increase competitiveness of the bridge while reducing the negative
impacts to the surrounding community.
Overnight Parking in Weed, CA: The City of Weed developed a parking lot to accommodate
30 trucks on industrial-zoned city-owned land. The community was supportive of the
development and recognized the need for truck parking to support the local economy.
Park-and-Ride Lot in Fallbrook, California: North of San Diego, at Interstate 15 (I-15) and
State Route 76 includes an area for dedicated truck parking. There are 11 designated truck
parking spaces.
These shared facilities provide parking in areas of high truck parking demand, and benefit from
economies of scale in design, operation, and maintenance compared to parking supporting a
single business. Table 15 summarizes the benefits and potential barriers for implementing shared
parking areas.

Public-Private Partnerships
P3s are partnerships for developing, operating, and maintaining infrastructure when there are
substantial public and private interests and benefits. The public sector invests its land, time,
expertise, funding, or other resources to benefit residents and the traveling public. The private
sector invests its resources when it expects a return on investment. Truck parking is an
appropriate P3 candidate because it sits at the nexus of public interests and private industry
operations: when truck parking is adequate, safety and mobility are improved, as is the economic
competitiveness of private industry.
State and Federal law may affect the feasibility of some truck parking P3s. For example, 23
U.S.C. 111 prohibits commercialization of Interstate right-of-way, with the exception of certain
activities such as providing vending machines. Some turnpikes or toll roads with Interstate
designations that were constructed without Federal funds as well as certain commercial
establishments on other Interstate highways that were in existence prior to January 1, 1960 and
meeting certain other conditions specified in 23 U.S.C. 111 are exceptions to this rule. Other
locations of high truck parking demand such as U.S. Highways and local or regional roadways
near ports and industrial uses could present good candidates for P3s. Table 16 summarizes
benefits of and barriers to implementing P3s.

maintenance costs provided by a private partner. The Maryland Transportation Authority
(MDTA), the State’s toll authority, entered into an agreement with Areas USA to redesign and
reconstruct two travel plazas along I-95.
57
MDTA’s public benefits included modern travel
plazas with fuel, truck parking, restaurants, and convenience items. Their private partner can
generate revenue from sales at the travel plazas, and the agreement includes a commitment to
return a percent of gross revenue to MDTA. The agreement includes at least $400 million to
MDTA over the 35-year agreement.
57
The travel plazas located in the right-of-way of Interstate I-95 in Maryland are exempt from the prohibition
against commercialization of the Interstate right-of-way under 23 U.S.C. 111. These travel plazas, in existence at the
time 23 U.S.C. 111 was enacted, meet the grandfather provisions under 23 U.S.C. 111(a).
Maryland Transportation Authority I-95 Travel Plaza P3
The Maryland Transportation Authority (MDTA) is responsible for Maryland’s tolled
highway system, including I-95. During 2011, MDTA released a Request for Proposals (RFP)
to enter into a 35-year concession agreement for travel plazas along the corridor. There were
three goals for the P3 arrangement:
Obtain new or like-new facilities to replace the current Chesapeake and Maryland
Houses.

Truck Parking Development Handbook

5. CONCLUSIONS
Jason Rivenburg’s death highlighted the challenges truck drivers face daily. In 2012, Jason’s
Law brought attention to the truck parking situation across the Nation. The March 2020 Jason’s
Law Truck Parking Survey results show that the number of truck parking spaces in the U.S. has
risen 6 percent in recent years; but it is not enough. Every day, thousands of truck drivers
continue to experience frustration looking for parking to rest, comply with State and Federal
safety laws, or stage loads for customer appointments. Drivers and truck stop operators continue
to report frequent truck parking shortages. States and communities frequently report trucks
parked in undesignated areas, and unfortunately some cities are responding with prohibitions that
only make these issues worse.
Providing safe and secure truck parking has positive benefits for truck drivers, the traveling
public, municipalities, States, and private industry. Driver safety, traffic safety and efficient
freight movement all depend on access to truck parking. Since Jason’s Law, progress has been
made to better assess truck parking needs, especially those needs associated with Federal HOS
regulations. But significant challenges remain to address the needs for truck parking in the right
locations. This Handbook presents tools and strategies for local planners and land use officials to
integrate truck parking into local planning efforts, land use and zoning policy, and community
education efforts to improve the state of truck parking in their communities.
Projects that increase the availability of truck parking spaces can generate public and private
benefits across many dimensions, safety, infrastructure preservation, supply chain reliability and
profitability: These improvements not only reduce trucking costs, but they also reduce
community impacts (emissions, congestion, safety, etc.). Making it easy to find parking also
reduces the need for truck drivers to park in undesignated locations, many of which are unsafe
and are a nuisance for local communities. Truck parking supports broader economic
development, including jobs, income, and taxes in the local economy. These benefits derive from
reductions in transportation costs that enhance regional competitiveness of businesses, from
establishments that serve truck drivers locating in the surrounding area, and from the operations
of the parking facility.
The successful implementation of truck parking areas depends on collaboration between the
public and private sectors. The barriers to providing additional truck parking are many; funding
for facility construction and maintenance is limited and finding locations to provide parking is
difficult in the areas with highest demand due to land cost and availability. Urbanized areas
especially around industrial, warehousing, or commercial clusters and freight hubs such as ports,
international gateways, and intermodal facilities have the greatest land-related challenges due to
the concentration of existing development. When there is limited land and resources to meet
truck parking needs, P3s have proven to be a successful mechanism to implement on-site parking
and shared parking facilities. The final chapter of the Handbook provides case studies showing
successful examples of how communities across the Nation of implemented parking
developments.
Through proper planning and appropriate land use policies truck parking can be in harmony with
community livability goals. This Handbook provides State and local practitioners with resources
to plan for and implement truck parking that supports local economies, while minimizing

negative externalities. The Handbook presents strategies and case studies for developing truck-
parking that supports freight transportation safety corridors, integrates parking needs with truck
generating facilities and ensures compatibility with adjacent land uses. This Handbook is
designed to help communities address the challenges associated with modern industrial,
warehousing, and commercial developments that generate truck traffic and create demand for
truck parking.
