New intersections will be added in 2012, 2013

March 06, 2012

The city of Aurora, Ill., is working to spread its network of traffic signal monitoring devices that allow remote analysis of traffic patterns, according to the Aurora Beacon-News.

The system consists of high-tech traffic signals and cameras at various intersections across town. The signals send data on traffic light patterns back to City Hall, while the cameras can instantly assess the number of vehicles sitting at an intersection. Together, the devices let city traffic engineers find trouble spots and plan accordingly.

Expansion of the network in 2012 will include eight traffic signal upgrades on Eola Road and interconnection of several signals on Commons Drive. The combined cost of the two projects is estimated at approximately $175,000; they will be funded by a combination of city motor fuel tax funds and federal grants.

City engineers will also improve the recording capability of traffic cams, allowing video storage for up to seven days.
