Signal phase and timing extended message
Webprogress through the signals without stops. Furthermore, bandwidth-based signal timing is preferred because it better meets drivers’ expectations. Besides general signal timing parameters of cycle length and phase split, phasing sequence is perhaps the most important element when maximizing progression bandwidth is desired (3, 4). WebSignal Phase and Timing (SPaT) messages contain information about the signal phase and associated timing of each phase. Utilizing this data can help ensure that traffic lights at intersections are properly timed, allowing transportation agencies to directly manage traffic throughput along corridors. There are generally two ways that agencies ...
