Overview of TPAS

Truck Parking Availability System

Corridor Map

In April 2019, the I-10 Corridor Coalition was awarded a $6.85 million U.S. Department of Transportation (USDOT) Advanced Transportation and Congestion Management Technologies Deployment (ATCMTD) grant to implement a Truck Parking Availability System (I-10 TPAS) along the I-10 corridor. In addition to the grant, the Coalition states are matching the funds 1:1, allowing the Coalition to leverage $13.7 million for the TPAS project.

The I-10 TPAS is a technology system that will detect, monitor, and provide real-time truck parking availability information to truck drivers, dispatchers and other interested stakeholders through roadside dynamic message signs, smartphone and in-cab applications and online via websites and traveler information sites. Using this information, truck drivers and dispatchers can make informed parking decisions which will improve safety, efficiency, and mobility and reduce emissions along the I-10 corridor. The system will monitor and report on available truck parking spaces at 37 public rest areas in California, Arizona, New Mexico, and Texas, providing approximately 550 truck parking spaces.

The project is planned to be deployed over a 4-year period and will “go live” with the launch of the TPAS in 2023 and follow up with ongoing operations and maintenance of the system.

Information Dissemination

Dynamic Parking Availability Signs (DPAS) will be placed upstream from the parking areas. These signs will provide drivers with real-time advanced warning ahead of the parking site to allow drivers to consider alternate plans if a location is full.

Smartphone and web-based services may also be used to provide data to drivers and dispatchers. The Coalition will work with developers to integrate the feed into existing applications.

 

Project Benefits

The I-10 Freight Corridor Study estimated the economic impact of freight moving along the I-10 Corridor at $1.38 trillion annually. The I-10 Corridor Coalition TPAS project can help support the economic productivity of this critical commerce route by:

  • Improving mobility and safety along this critical freight Corridor;
  • Reducing infrastructure damage and diesel emissions; and
  • Saving commercial truck drivers thousands of dollars a year in lost earnings and productivity.

The implementation of TPAS may also serve as the foundation for future technology implementation along the Corridor, including integration of weather or other alert systems, a truck parking reservation system, and automated and connected vehicle and infrastructure technology.
