When the best coordination has been determined the Traffic Signal Timing Team implements the new timing. This may require that the timing of the intersections be adjusted to facilitate the best flow of vehicles. When the data has been collected a study is done to determine the best timing and coordination of all intersections involved. This requires that City staff gather data on the volume, speed, distance between signals, and the timing of individual intersections. How Traffic Signals are CoordinatedĬoordinated signals attempt to provide green lights for the major vehicle flow on a street. They drive the arterial before and after the new coordination timing is applied to determine the effectiveness and efficiency of the new coordination. The Signal Timing Team gathers data, evaluates, and studies the major and minor arterial streets. The Traffic Signal Timing Team is made up of the City's Traffic Engineer and technicians who specialize in the timing and coordination of the traffic signals. This information is also made available to the public through the City's Web site, the City's cable television Channel 18 and by direct communication with the local television and radio stations. The system is a technological system that includes video cameras, computers, vehicle detection, variable message signs, and alternate routing. This system provides transportation information to motorists, emergency personnel, and transportation specialists. The Intelligent Transportation System (ITS) is an integral part of the State and National effort to provide innovative transportation solutions. This is a centralized location that allows us to monitor and maintain the City's traffic signals and congestion management equipment. The City of Colorado Springs Traffic Management Center is the City's facility that houses the ITS equipment and personnel. There are several components to the City's traffic signal timing and coordination system: the Traffic Management Center, Intelligent Transportation System (ITS), Traffic Signal Timing Team, and public participation. Because of the high pedestrian volumes, the downtown signals operate under a pre-timed plan with the lights changing constantly to serve all approaches and pedestrian traffic.Ībout Signal Timing Timing and Coordination Program With the exception of the downtown area, all traffic signals in the city have vehicle detectors for side street detection. If the pedestrian activates the push button and crosses prior to receiving the walk light, the signal will still change its sequence. The same is true for pedestrian crossings. If this vehicle turns after this time the call for the green signal is still made.

The detectors will recognize a right-turning vehicle sitting at an intersection for greater than 10 seconds. The traffic signal has detected a vehicle that has subsequently made a right turn at the intersection.If you suspect that a video detector is not functioning correctly, please call 71. In this case, the traffic signal falls into a fail-safe operation and sequences green light phases to the side street to ensure access. Video detectors running 24 hours a day sometimes malfunction. The video detectors are not operating correctly.If the signal is sequencing to the side street for no apparent reason, it could be because of one of these situations: A: For most traffic signals in Colorado Springs the signal rests on the green light for the major street in order to serve the greater volume and switches to the side street upon demand.
