Transit Signal Priority (TSP)

 When we talk about Traffic Signals, we find there are — Traffic Control Signals, Fixed Time Signals, Manually Operated signals, Traffic Actuated (automatic) Signals, Pedestrian Signals, Special Traffic Signals. In the US, implementing a new system —  Traffic Signal Priority was initially difficult to work on due to several reasons, including: Technical feasibility and cost-benefit; Not accurate detection products; Limited installations of vehicle location systems by transit properties; Absence of standards; Traffic signal controllers could not support TSP; Centralized TSP TSP organizes and manages requests for priority from multiple vehicles using a central system. The priority request system located on the transit vehicle is usually equipped with a GPS that allows direct access to the traffic management center. Hence, the decision to request priority can be determined as per the requests from all the field vehicles. The need to have a framework is based on traffic management; it can

 When we talk about Transit Signal Priority , the basic fact lies that by using Preemption and Priority settings for traffic signals, we can modify the signal timing and prioritize specific vehicle types, such as buses, trucks, emergency vehicles, or trains. These systems primarily aim to speed up travel times, improve safety, and clear the way for priority vehicles to reach their next destination. Let us understand the main distinction - Signal Preemption: Signal Preemption can be applied to emergency vehicles, trains, and light rail. Unlike priority, it takes control of an intersection and immediately turns all directions red except for the one in which an emergency vehicle is traveling. The system makes it easier for emergency vehicles to reach their destination by vacating a path through traffic signals. It enhances safety by providing a red light to all vehicles, pedestrians, and bicyclists who must stop and permit the emergency vehicle to proceed. Signal Priority: Transit vehicle
