Transit Signal Priority

Transit Signal Priority (TSP) technologies help improve travel efficiency by giving transit vehicles priority at traffic signals. Using sensors, communication networks, and intelligent signal systems, these technologies adjust signal timing in real time to reduce delays and improve schedule reliability. Vehicle-to-Everything (V2X) and Intelligent Transportation Systems (ITS) innovations are expanding the impact of TSP. These advancements improve transit safety and enhance systems such as Bus Rapid Transit (BRT). Explore executive briefings and data visualizations to see how these technologies are making travel smoother, smarter, and safer across the nation.
