TSP (Transit Signal Priority)

Transit Signal Priority (TSP) is a system that helps buses and streetcars move more smoothly through traffic signals. When a vehicle approaches an intersection, TSP communicates with traffic lights to extend green signals or shorten red signals, allowing public transit vehicles to pass through more quickly. This reduces delays, improves schedule reliability, and encourages public transportation use by making it faster and more dependable. TSP is designed to optimize traffic flow for transit vehicles without significantly impacting other road users, balancing efficiency and safety in urban transportation.
