Transit Signal Priority (TSP)

Q: What is Transit Signal Priority?

Transit Signal Priority (TSP) is a traffic signal control strategy that modifies normal signal operations to reduce delay for transit vehicles, typically by extending green time or shortening red time when an eligible vehicle is present. Expanded Explanation 1. Technical Function and Core Characteristics TSP uses detection, communication, and traffic signal control logic to adjust the timing of signal phases when a transit vehicle approaches an intersection. It operates within predefined rules

Q: How widely is Transit Signal Priority used?
