PHOENIX (3TV/CBS 5) - Since they were introduced in January, Arizona's wrong-way detection systems have detected dozens of cars from heading the wrong way on I-17 off ramps.
A total of 47 wrong way drivers have been detected since January.
According to ADOT, that is 47 times where nearby drivers were immediately alerted to trouble heading toward them.
The system is designed to alert ADOT, the Department of Public Safety as well as other freeway drivers when a wrong-way vehicle is detected.
The majority of wrong-way drivers detected by the system turned around, or “self-corrected,” on I-17 off-ramps and did not enter the freeway, according to ADOT.
Ninety cameras are located along I-17 and soon more could follow.
Arizona's Family learned ADOT is seriously considering expanding the program beyond I-17.
"I think you're going to see more and more of that along the valley freeway system," said Doug Nintzel, an ADOT spokesman.
According to ADOT, cities in Texas, Florida and California are now studying the technology and looking to follow Arizona's lead.
Arizona was the first state in the country to develop the thermal camera alert system to detect and track wrong-way vehicles.
