Transit Signal Priority (TSP)

In today’s fast-paced urban environments, efficient traffic management is essential. EMTRAC’s Traffic Signal Priority (TSP) system offers a cutting-edge solution to improve traffic flow, reduce delays, and enhance safety for all road users. By giving priority to transit vehicles, emergency responders, and other authorized fleets, EMTRAC ensures faster and more reliable travel across intersections. Traffic congestion is a persistent issue in growing cities, often leading to increased fuel consumption, higher emissions, and lost time. EMTRAC’s TSP technology addresses these challenges by using GPS and wireless communication to detect approaching priority vehicles. When a designated vehicle approaches a signalized intersection, the EMTRAC system communicates with the traffic signal controller to either extend the green light or shorten the red light, thereby allowing quicker passage. EMTRAC’s Traffic Signal Priority system is not only beneficial for public transportation agencies but als...

Efficient traffic management is crucial for improving safety, reducing congestion, and supporting smart city initiatives. EMTRAC’s Traffic Signal Priority system offers an intelligent solution that allows emergency and transit vehicles to move through intersections more efficiently by adjusting signal timing in real time. The EMTRAC Traffic Signal Priority system uses a combination of GPS, wireless, and cellular technology to detect priority vehicles and communicate with traffic signal controllers.

This advanced solution reduces response times for emergency services and helps transit vehicles maintain reliable schedules. It also lowers fuel consumption and emissions by decreasing stop-and-go movement, making it an environmentally friendly option. EMTRAC’s Traffic Signal Priority system integr...

Traffic Signal Priority (TSP) is an advanced traffic management strategy that provides priority treatment to specific vehicles—such as buses, light rail, emergency vehicles, and public transit—at signalized intersections. By dynamically adjusting traffic light phases, TSP helps reduce delays and improve travel time reliability for essential transportation modes. The TSP system typically includes components like vehicle detection devices and intelligent signal controllers. These tools work together to identify priority vehicles and modify signal timings in real-time, offering a smoother and faster route through busy junctions. Types of Traffic Signal Priority Techniques: TSP can be implemented in several ways, depending on its purpose and the transportation needs: Passive Priority Early Green (Red Truncation) Green Extension Dedicated Transit Phases Phase Skipping or Rotation Adaptive/Real-Time Control TSP Implementation Approaches: Depending on the system’s goals, different TSP strate...

Traffic Signal Priority (TSP) is a proven solution to improve transit efficiency by reducing the time vehicles spend waiting at red lights. By making slight adjustments to traffic signal cycles, TSP ensures that transit vehicles experience fewer delays. It either shortens red signals to allow a stopped vehicle to move or extends green signals to let an approaching transit vehicle pass without stopping. Traffic Signal Priority is widely used for street-running transit systems such as buses, streetcars, and light rail, ensuring faster and more reliable service. It is especially beneficial in high-frequency transit areas where efficient movement is critical. The cost of implementing TSP varies based on the number of signalized intersections and transit vehicles equipped with priority technology. Typically, the traffic signal operating agency covers the intersection equipment costs, while the transit agency funds onboard vehicle equipment. The EMTRAC TSP system has been a trusted choice a...

Traffic congestion is a growing challenge in urban areas, and smart traffic management solutions like Traffic Signal Priority (TSP) and Transit Signal Priority (TSP) help improve mobility. While both strategies enhance traffic efficiency, they serve different purposes. Traffic Signal Priority modifies signal operations to optimize traffic movement, benefiting public transit and emergency vehicles. On the other hand, Transit Signal Priority is specifically designed for in-service transit vehicles, such as buses or streetcars, giving them extended green lights or reducing red light wait times. One key distinction is that Emergency Vehicle Preemption (EVP) overrides normal traffic signals for critical situations, such as fire trucks responding to emergencies, ensuring a clear path through intersections. In contrast, Transit Signal Priority only adjusts signals to improve transit efficiency without significantly impacting other road users. By integrating advanced technologies like GPS, ve...

Traffic Signal Priority (TSP) helps leverage a vehicle's current location and wireless communications technology to extend the green light of a traffic signal and allow a Pace or CTA bus to help reduce travel times and ensure on-time arrival and proceeding at an intersection when a bus is severely behind schedule. When looking at traffic signal priority, the basic reality is that using traffic signal priority and preemption settings can change signal timing and give priority to certain types of vehicles such as emergency vehicles, trucks, buses, or trains. This system aims to speed up travel times, help improve safety, and provide a way for priority vehicles to get to their next destination. More than 50 percent of area transit users can take advantage of faster, more reliable bus service. On buses equipped with signal priority, passengers will see significantly fewer delays at traffic signals, allowing them to reach their destinations on time, with less disruption to the overall ...

 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...
