What is meant by "traffic signal coordination"?

Traffic signal coordination refers to the synchronization of multiple traffic signals along a corridor to enhance the flow of vehicles. This process aims to create a more efficient traffic flow by ensuring that vehicles encounter a series of green lights when traveling along a major roadway. By effectively coordinating the timings of the traffic signals, it is possible to minimize stops, reduce travel time, and improve overall traffic efficiency.

Achieving coordinated signal timing involves analyzing traffic patterns, determining appropriate cycle lengths, and timing offsets between signals to create "green waves" that facilitate smooth traffic movement. This approach helps to alleviate congestion and can contribute to improved safety for all road users, including bicycles and pedestrians. The ultimate goal of traffic signal coordination is to ensure that the signals work together harmoniously, rather than operating independently, thus enhancing the user experience for drivers and improving the functionality of the road system.
