What goal does Transit Signal Priority (TSP) aim to achieve in relation to other vehicles?

Answer: C — To optimize the flow of public transit vehicles

Transit Signal Priority (TSP) is primarily designed to enhance the efficiency of public transit systems by optimizing the flow of transit vehicles. By prioritizing buses or trams at signalized intersections, TSP allows these vehicles to maintain schedules, reduce delays, and improve overall service reliability. This is crucial in creating a more attractive public transit system, encouraging more people to utilize it, thus supporting sustainable transportation goals. By allowing transit vehicles to pass through intersections more readily compared to other traffic, TSP can significantly reduce travel times for public transit. This not only benefits transit users but can also lead to increased ridership, which in turn helps to lessen road congestion overall. Therefore, the focus of TSP is on ensuring that public transit systems operate as efficiently as possible, which is encapsulated in the goal of optimizing the flow of public transit vehicles.
