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.

More than a showcase for innovation, the center was—and continues to be—a dynamic outdoor laboratory where new traffic materials, systems, vehicle safety and public safety products are tested in real-world conditions. Now, with 3M expanding

    In sharp contrast to many other countries drivers in Sweden support speed cameras and the planned expansion of the automated enforcement network. Sweden is embarking on a massive expansion of its speed camera network and is doing so with both a very high level of public acceptance and without its drivers feeling persecuted; a feat the administrations in many other countries would like to emulate. So how did this envious state of affairs come about? Magnus Ferlander director of business development and ma

    Geoff Hadwick attended ASECAP’s 2015 Study Days meeting in Lisbon and found a frustrated European tolling sector undertaking some soul searching. The international road tolling industry its failing to make it case and the sector is losing out to a range of other socio-political lobby groups according to International Bridge, Tunnel and Turnpike Association (IBTTA) chief executive Pat Jones. Speaking at the recent 2015 ASECAP Study Days conference in Lisbon, Jones issued a stark warning: “Tolling is still o
