Reply to comment by tesla3by3 in Why are traffic lights in Pittsburgh timed so poorly? by rickyrichboy

This isn’t quite what the op is talking about but in Forest Hills some intersections have smart lights with sensors so that side streets only go green when there is a vehicle.

Lots of streets in Pittsburgh have them as well. I was referring to the cross streets in E Lib, all of which are heavily used, so a sensor wouldn't do much good, as there would almost always be cross traffic waiting.
Another commenter said that the cross streets further out Penn have the sensors.
