Timing for transit signal priority.

This paper examines and discusses the resistance that traffic engineers responsible for traffic signal management often exhibit towards implementing Transit Signal Priority (TSP). While fairly commonly implemented, TSP has often been only grudgingly accepted and in fact often resisted by signal operation engineers. Often only after politically derived projects require its use is TSP implemented, and often then with the attitude that it is disruptive to “normal” operations and “interferes” with carefully engineered signal timing. This paper will discuss the nature and likely causes of this resistance, and argue that such resistance is understandable but not warranted or desirable, and that TSP can and should be considered a normal component of the traffic signal timing and operations.
