TPAS Fact Sheet Image

The TPASTruck Parking Availability System will monitor truck parking availability and provide real-time information to truck drivers. The TPAS will be deployed on I-10 in California, Arizona, New Mexico and Texas. The TPAS is funded through $6.85 M ATCMTD Grant and 1:1 state matching funds. The TPAS system will “Go Live” in 2023 and track performance measures during ongoing operations.


Frequently Asked Questions about the TPAS

What is the I-10 TPAS?

The I-10 Corridor Coalition, a partnership of state departments of transportation from California, Arizona, New Mexico, and Texas, is deploying a Truck Parking Availability System (TPAS) along the I-10 Corridor in these states. TPAS will provide real-time truck parking information to assist truck drivers and dispatchers in making informed parking decisions and improve safety, mobility, operations, and air quality along the corridor.

What is the I-10 Corridor Coalition?

The I-10 Corridor Coalition is a voluntary coalition of the departments of transportation for California, Arizona, New Mexico, and Texas. The Coalition is committed to multi-jurisdictional coordination to promote safer and more efficient travel for both people and freight along the I-10 corridor by sharing expertise and resources, joint testing technology, and implementing innovative transportation improvements and best practices. The I-10 TPAS project is one of the Coalition’s first major initiatives to help achieve this goal.

Where will the I-10 TPAS be deployed?

The TPAS will be deployed at 37 public rest areas along the I-10 corridor in California, Arizona, New Mexico, and Texas.

How will the system work?

Truck parking detection equipment will be deployed at each of the 37 public rest areas to monitor truck parking availability. The technology will be installed at the rest area entrance and exit driveways to count trucks entering or exiting or may be installed within individual truck parking stalls to detect the presence of trucks within each space. The system collects the truck parking availability data and disseminates it to dynamic truck parking availability signs (DPAS) and state traveler information websites. A data feed is also provided by each state, making the data available to 3rd party website and mobile phone application developers as well as in-cab information system developers.

How will I be able to access the TPAS information?

Dynamic Parking Availability Signs (DPAS) will be placed upstream of public truck parking areas. These signs will provide drivers with real-time truck parking availability information for several upcoming parking areas to allow drivers to consider alternate plans if a location is full. The Coalition will work with 3rd party website, mobile phone, and in-cab information system application developers to integrate the truck parking availability data feed into existing applications. Drivers and dispatchers will then be able to access this information through in-cab information systems and smartphone and web-based services.

How is the project funded?

The I-10 TPAS is funded through a $6.85 million U.S. Department of Transportation (USDOT) Federal Advanced Transportation and Congestion Management Technologies Deployment (ATCMTD) Grant. The four states have agreed to match the grant 1:1, bringing the total project funding to $13.7 million over the four-year project implementation period.

When will the Project Open?

The I-10 TPAS project is scheduled to “go live” in Spring 2023.
