Traffic Signal Priority

Traffic Signal Priority

Transit Signal Priority (TSP) is an important element of Bus Rapid Transit (BRT) that involves coordinated efforts between transit vehicle detection systems, traffic signal control systems, and communication technologies. In a nutshell, TSP means that buses signal their impending arrival at a signalized intersection and then receive the green light to drive straight through. The New York City Department of Transportation (NYCDOT) and Metropolitan Transportation Authority (MTA) are embarking on an ambitious program to provide TSP to 6,000 buses in New York City. A key component of the project is New York City’s dedicated broadband wireless infrastructure (NYCWiN), which was created by the city’s Department of Information Technology and Telecommunications (DoITT) to support public safety and essential urban operations. Because NYCWiN supports the implementation of TSP without any additional hardware or infrastructure changes, this approach is particularly cost-effective and attractive for widespread implementation of TSP in New York.
