use zones to trigger it with vehicles!
thats a good idea and when thers no cars they go red
or when a car comes, it IS red =D
only if a car is coming form another direction tho. use complex variable/zone combination to do it
Why not just have an automatic timer? Not a stupid complex zone thingy. What if a car moves backwards? What if the car stops because the driver has to do something?Just have a timer like in real life.
