A network-based Transit Signal Priority (TSP) system typically consists of three main components: a transit vehicle detection system, a traffic signal control system, and a central transit or traffic management center. Together, these elements coordinate to reduce delays for public transportation vehicles at signalized intersections.
The key difference between TSP and Traffic Signal Preemption lies in how the signal timing is manipulated. TSP makes calculated adjustments to normal signal cycles to enhance transit service reliability—favoring buses or streetcars without fully disrupting the sequence. In contrast, preemption interrupts regular traffic signal operations altogether, giving immediate right-of-way to high-priority vehicles such as ambulances, fire trucks, or trains.
A Traffic Signal Preemption Transmitter plays a critical role in this process. Installed on emergency vehicles, it sends a signal to the traffic control system to request immediate green light access as the vehicle approaches an intersection. This reduces response times, improves safety for emergency personnel, and helps avoid accidents at crossings.
While emergency vehicle preemption focuses on swift, safe passage during urgent events, TSP is more about optimizing overall transit performance. TSP helps with schedule adherence, improves travel times, supports real-time transit data, and boosts overall roadway efficiency for public transport.
By understanding the unique functions of traffic signal preemption transmitters and TSP systems, cities can apply the right tools to improve both emergency response and day-to-day transit operations.
