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.

    Bridging the highway travel information gap
    A new traffic management solution is attempting to bridge the gap in information available on freeways and arterial roadways. Andrew Bardin Williams reports. Agencies responsible for national networks of roads around the world have the ability to measure, analyse and disseminate accurate travel information to drivers. Millions of dollars go into data collection infrastructure to collect traffic congestion and travel time information on major freeways or highways. For example, a driver on the I-210 in the Lo

    Doha implements traffic control system
    Expansion of ITS systems has accelerated in Qatar this year, with rapid deployment of a traffic control system in Doha. Less than 10 years from now an extensive system of ITS technology will be operating in Qatar, informing and directing users of the country’s roads. That can be stated with confidence for a number of reasons: the world’s richest country per capita will host the World Cup in 2022 and is understood to be planning to develop sophisticated systems of ITS for road safety and traffic managemen

    Smoothing the path to reducing traffic pollution
    David Crawford reviews a new approach to traffic smoothing. A key objective for the Californian city of Bakersfield’s upgraded traffic operations centre (TOC), which opened in June 2014, is to help improve living conditions in a region with one of the worst air quality problems in the US. The TOC is speeding up the smoothing of traffic flows by delivering faster and better-informed traffic signal retiming and synchronisation.

US cities are vying with each other in developing schemes to create a new generation of connected places. Their strategies include taking advantage of their streetlight poles’ height and ubiquity to give them new roles in supporting intelligent nodes. They are now being equipped for collecting real-time data on key transport
