ADOT advances wrong-way detection with US$3.7 million project

A US$3.7 million project by Arizona Department of Transportation (ADOT) to construct a thermal detection system to detect wrong-way vehicles and alert other drivers and law enforcement has been approved by the State Transportation Board. Once operational, the system will use thermal cameras, warning signs for wrong-way drivers and advisories for right-way drivers along a 15-mile stretch of I-17.

A US$3.7 million project by 6576 Arizona Department of Transportation (ADOT) to construct a thermal detection system to detect wrong-way vehicles and alert other drivers and law enforcement has been approved by the State Transportation Board.


Once operational, the system will use thermal cameras, warning signs for wrong-way drivers and advisories for right-way drivers along a 15-mile stretch of I-17. In addition, the system will automatically focus highway cameras on the wrong-way vehicle and send automated alerts to the Highway Patrol.

On freeway ramps, wrong-way vehicles will trigger alerts, including illuminated signs with flashing lights, aimed at getting drivers to stop. The system will immediately warn other drivers through overhead message boards as well as law enforcement. Cameras in the area will automatically turn to face the wrong-way vehicle so traffic operators can better track it.

On the freeway, thermal cameras placed at one-mile intervals will signal when a wrong-way vehicle passes so State Troopers plan their response and get out in front of the wrong-way driver, providing a faster response.

Construction of the thermal camera pilot system is expected to begin this autumn and will take around seven months to complete.

    Arizona’s traffic operations centre was built more than twenty years ago; the first traffic camera was installed over Interstate10 in 1990. That’s all changed now thanks to a recent US$2.1 million upgrade of the camera system by Arizona Department of Transportation (ADOT) which replaced cables with fibre optic lines, so the cameras now show fresh images every ten seconds rather than every five minutes. The upgrade has also replaced the 32 video screens in the traffic operations centre, enabling staff to sca

    David Crawford sees how Missouri is using commercially available information to rapidly improve monitoring and driver information on rural highways. Missouri is a predominantly rural state with the second largest number of farms in the country and agriculture the main occupation in 97 of its 114 counties. US statistics starkly reveal how road accidents in rural areas tend to be more serious than in urban regions and of the 32,000 US motorists killed each year, 54% die on roads in rural areas even though onl
