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
Two traffic lights by me operate differently. One unless you push the button or a vehicle is in the detection loop it does not change at all. There is a X walk count down timer for the main road and the timer counts down to 0 and then goes back to cross.
The other one the lights change from green to red on the Main Street but the crossing does not give a walk signal to cross unless you hit the button. It is also a shorter time for vehicles to turn from the side street.
