The city of Abilene integrated vehicle detection and signal control systems at 63 intersections to allow TMC operators and maintenance technicians to respond to problems remotely, saving the city time and money by reducing the need to drive to intersections.

The upgrade included new traffic signal controllers; new traffic signal control cabinets; a city-wide wireless broadband radio communications network, Ethernet switches to allow communications between systems hardware, and the deployment of an advanced vehicle detection system.

The vehicle detection system is designed to use both video and radar technologies to provide stop bar and advanced zone detection, and enable advanced safety for adaptive control applications. Information from camera systems will be transmitted using a remote communications module that provides both local and remote management of data and video over the Ethernet, enabling system operators to manage the system from a central location such as a TMC.

Cost of the system was estimated at $1.5 million.
