Traffic signal synchronization refers to the functioning relationship between active signals along a corridor. A common cycle length is established. All intersections in the coordinated system have the same cycle length. By maintaining a constant relationship between the signals at all times, there is a greater likelihood that mobility will be improved. This does not mean that the signals will provide a green light at the same time for the entire length of a corridor; rather, that each signal will quite literally be synchronized with the entire system, allowing for more efficient mobility.
