For lights to be timed they must change in progression at about the speed limit. In other words after you go thru a light, then if driving at the speed limit the next one will change after the one you just past and so on so you you keep getting green lights.
Now that is for the direction YOU are traveling. The other side is going against the progression and will get most lights.
I don't see how it's possible for lights to be timed in both directions at the same time.
