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?

On most it’s a placebo. It makes you feel like you’re doing something positive. On some where there is only occasional pedestrian traffic it does actually signal that someone is there looking to cross and triggers the light to give a walk signal at the next cycle opportunity.
