I-10 Truck Parking Availability System Texas

What is I-10 TPAS?

The I-10 Truck Parking Availability System (TPAS) is a technology system that helps detect, monitor, and provide truck parking availability information. The I-10 TPAS project is part of a four-state I-10 Corridor Coalition initiative to improve safety along the corridor. Using dynamic message signs, smartphone and in-cab applications, websites, and other traveler information sites, TPAS will give truck drivers and dispatchers real-time information, helping them make safe parking decisions at 37 public truck parking sites along I‑10 in Texas, New Mexico, Arizona, and California.

TPAS in Texas

TxDOT will deploy TPAS at 16 Safety Rest Areas (SRAs) and two Travel Information Centers (TIC) along I‑10 in Texas. The TPAS deployment will consist of:

  • Vehicle detection technology and CCTV cameras at the SRA and TIC sites
  • Dynamic Parking Availability Signs (DPAS)

Each TxDOT district along I-10 will let a construction project to build the system using design-bid-build delivery. The detection equipment will be procured separately and furnished by the state for the contractor to install under each TPAS construction contract.

Upon completion of installation and testing, district offices will coordinate with the Traffic Safety Division and Travel Information Division to integrate TPAS into Lonestar TM and DriveTexas.


 The I-10 Corridor Coalition TPAS project is scheduled to be deployed and operating by 2024.
