Closely spaced signals, particularly along a main corridor, are typically coordinated to improve the flow of traffic. This can reduce delay, emissions, control speeds, and provide other benefits by moving a platoon or group of vehicles along the coordinated corridor.

Subsequently, when a series of coordinated traffic signals prioritize continuous flow through those intersections - a green wave results. This process is designed and implemented by traffic engineers - it can either be static (meaning pre-programmed) or dynamic (meaning reflective of sensor data).

Vehicles traveling at or near the progression speed will be able to traverse the corridor through the green band. Vehicles traveling too fast will arrive on red before the signal changes to the green phase and vehicles traveling too slowly will also arrive on red by missing the green phase.
