Summary Information

The Chattanooga Area Regional Transportation Authority (CARTA) installed a new transit signal priority system to improve on-time performance for buses operating in a heavy retail area of Hamilton Place. Instead of increasing their fleet size and adding more buses to compensate for increased traffic delay, the city installed a traffic signal priority system for $250,000. Twenty-seven agency buses were equipped with transit signal priority transmitters, and 10 intersections on Gunbarrel and Shallowford roads and near the mall were equipped with receivers. The transmitter aboard the bus automatically transmits a signal to the receiver. If the traffic control light is about to change to red, the green time is extended 10 to 15 seconds to allow the bus to pass. Overall, the system was expected to improve operational efficiency and have minimal impacts on other traffic.

System Cost

Cost: $250,000 (2001).
