There are long waits at the traffic lights, if that has anything to do with it. Lots of the traffic signal cycles are arranged to allow average-speed pedestrians the opportunity to cross all of Queens Blvd in one motion. The percentage of time that cars can cross intersections definitely reduces capacity.The capacity of a traffic light generally depends on the duty cycle, rather than the absolute length of the green cycle. This means the total cycles are longer. I'm sure if it was grade-separated, things would be very different. The problem with grade separation is providing an adequate number of crossings. Grade separation with an inadequate number of such crossings usually results in creating walls that depress adjacent neighborhoods. Eventually, traffic on the cross streets exceeds the capacity of the few crossings that were provided. The grade separated highway destroys the grid system making and its redundancy. The result is more congestion than the roadway eliminated. |
