The green wave
is an idea
in traffic flow
such that if you exactly follow the speed limit
between two or more traffic light
s, you will pass through them on green
. Going too fast
will ensure that you have to stop at each
traffic light for about 5 seconds.
Idealy, if an entire area is done with the green wave, the only time someone will have to stop is when making a turn (thus changing the traffic pulse) or driving unsafe (too fast or too slow).
