Transit Signal Priority

Transit Signal Priority (TSP) is a system that helps public transportation vehicles, like buses and trams, move more efficiently through intersections. When a bus approaches a traffic signal, TSP communicates with the traffic lights to extend the green light or shorten the red light’s duration, reducing wait times. This helps buses stay on schedule, decreases travel time, and improves overall transit reliability. TSP is designed to prioritize transit vehicles without significantly impacting other road users, balancing efficient flow for public transit with smooth traffic movement for everyone.
