Remote-monitoring system helps keep Arizona city moving

The Arizona Department of Transportation (ADOT) has installed a wireless communication system allowing technicians in Phoenix to monitor conditions and adjust signal timing accordingly on State Route 347 through Maricopa. The system has a series of infrared and video cameras installed at each SR 347 intersection, allowing an ADOT technician in Phoenix to see exactly what is happening and modify the length of traffic signals to improve traffic flow.

The Arizona Department of Transportation (ADOT) has installed a wireless communication system allowing technicians in Phoenix to monitor conditions and adjust signal timing accordingly on State Route 347 through Maricopa.

The system has a series of infrared and video cameras installed at each SR 347 intersection, allowing an ADOT technician in Phoenix to see exactly what is happening and modify the length of traffic signals to improve traffic flow.

Another part of the system automatically monitors travel times between intersections using wi-fi signals, such as those from smartphones. That anonymous information can alert ADOT technicians to delays.

Similar systems are used to remotely monitor traffic signals in Nogales, along State Route 77 in the Tucson area and in the Phoenix area.

The technology was installed this past summer in Maricopa. Over the coming months, researchers from the University of Arizona will evaluate the cost-effectiveness of the system.

    The Department of Transport (DoT) in Abu Dhabi has commenced work on a US$9 million adaptive traffic control central system project, which is expected to be completed by early 2015. The project will see the implementation of a new Scoot (Split Cycle Offset Optimisation Technique) adaptive traffic control system to improve traffic flow at the capital’s 125 main signalised junctions. Scoot, installed in more than 120 cities worldwide, is a tool for managing and controlling traffic signals in urban areas.
