I wanted to see whether the lights were being used effectively to let the motor-vehicle traffic flow without stopping, and what potential causes for slowdowns are.
On the one hand yes, a double parked truck which restricts the avenue to two lanes, does cause a build up: more flow is coming in than going out. But then there are some less obvious things: cars changing lanes, cars taking a right turn having to wait for pedestrians, and delinquent pedestrians.
