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.

For example, you would pay a set amount in exchange for a monthly travel package covering up to 100km of free taxi journeys in your home city (including a guaranteed 15 minute pickup) and public transport usage within a 1,500km radius of your home. Not only would this option be cheaper than owning and maintaining your own car, you would
