There are plenty of intersections where a walk signal comes on automatically, why do some intersections require a button push to initiate the walk signal when it doesn’t seem to make a difference in light timing or duration?
In: Engineering
It can 100% make a difference in areas where pedestrians traffic fluctuates heavily, or is rare.
With the button you can alter the timing of the lights based on demand.
For example if you have a busy arterial road and then a not busy side road, stopping the arterial road every minute for a side road/cross walk that might not even have anyone standing there is a waste of time.
Better to only stop when it’s actually needed
