A green wave is a maximum headroom zone
A green wave means that traffic on a road can drive more than 1 traffic light without having to stop. The traffic lights are so tuned that at a specified speed the lights are green and can thus be driven. The goal is not only to allow the motorist to drive faster but is mainly intended for safety. Because there is less stress (of having to stop) at the motorist, the alertness at dangerous moments would be higher. In addition, the clever use of a green wave can avoid a certain area.
