TPAS: AI-Powered Truck Parking System, Now Launched in Arizona

AI-Powered Truck Parking Availability System (TPAS) Now Active on Arizona’s Freight Corridor

Arizona has officially launched the Truck Parking Availability System (TPAS) along  I-10, developed by Streetline in partnership with the Arizona Department of Transportation (ADOT). The AI-powered system went live in mid-August 2025 and is now fully operational. It provides truck drivers with real-time, highly accurate parking availability data at multiple rest areas along the critical freight corridor, helping reduce stress and improve safety on one of the nation’s busiest highways.

How TPAS Works

TPAS uses AI-powered cameras to monitor when trucks enter and exit rest areas. It then calculates how many spaces are open and sends updates to drivers. This information is displayed on electronic highway signs and shared through apps and the AZ511 traveler system. With this tool, drivers can quickly see where parking is available instead of wasting time searching.

Why TPAS Matters for Truckers

Finding a safe place to park has long been one of the toughest challenges in trucking. Surveys show that most drivers spend more than half an hour searching for parking at the end of their shift. Because of this, many end up parking on ramps, shoulders, or other unsafe areas.

With this system, drivers get accurate, real-time updates. This reduces wasted miles, saves fuel, and lowers stress at the end of a long day. Most importantly, it improves safety by helping drivers make smarter decisions before they run out of hours.

Where TPAS Is Live in Arizona

Right now, TPAS is active at four rest areas along eastbound I-10:

• Ehrenberg, near the California border
• Bouse Wash, west of Phoenix
• Texas Canyon, east of Tucson
• San Simon, close to the New Mexico border

These locations were chosen because they are some of the busiest stops for truckers moving freight along the I-10 corridor.

A Multi-State Effort

TPAS is part of a larger project led by the I-10 Corridor Coalition, which includes Arizona, California, New Mexico, and Texas. The program has a budget of $13.7 million, with about half covered by a federal grant. The long-term goal is to expand the system across the entire I-10 corridor so drivers can count on real-time parking updates from state to state.

What Truck Drivers Can Expect

For truck drivers, the benefits of TPAS are clear:

• Less time wasted searching for parking
• Safer and more reliable rest breaks
• Reduced stress and fatigue
• Better fuel efficiency with fewer extra miles

This system is one more step toward improving life on the road, especially on one of the nation’s busiest freight corridors. As TPAS expands, truckers will have even more support in finding safe, legal parking when and where they need it.
