@Tubemeister @RustyFreewheel having a cooldown period is trivial and usually already part of the logic: you're only shortening the green light if there has been a minimum time it's been on, otherwise it would be a potential safety concern. And in places where the lights already change based on traffic (by detecting coming vehicles), there's already enough information to detect traffic volume to modify the logic from "low traffic, prioritize pedestrian beg button" to "high traffic, follow the light cycle". Because these are controlled by software, you can have arbitrarily complex rule tree to optimize for whatever goal you desire.
