Transit Signal Priority: When to Use This Strategy

Transit Signal Priority (TSP) is a tool designed to adjust the timing and phasing of traffic lights to assist transit vehicles that are delayed or arrive prematurely. TSP applications help improve the reliability and travel times of transit vehicles, particularly on roads with long signal cycles and significant distances between signals. In urban areas, the benefits of TSP are significantly enhanced when implemented alongside other strategies, such as transit-only lanes.

Key TSP Measures

Planned Measures

·        Extending Green Lights: Hold green lights for a few extra seconds when transit vehicles are approaching.

·        Restricting Red Lights: Reduce red light wait times for transit vehicles.

·        Green Phase Adjustment: Align the green light phase to coincide with the arrival of transit vehicles.

Additional Measures

·        Red Light Coordination: Halt other traffic at red lights to facilitate the movement of buses at stops and stations.

·        Bus-Only Signal Phases: Coordinate specific signal phases for buses and emergency vehicles to bypass traffic stopped at red lights.

TSP Strategy Considerations

·        Prioritizing Delayed Routes: Routes experiencing unexpected travel time delays are given priority.

·        Addressing High Traffic Volumes: High traffic volumes are a major cause of delays, and TSP helps mitigate this.

·        Managing Signal Distance and Periods: Long distances between signals and extended signal periods can be optimized with passive TSP, ideal for short block lengths and high passing frequency environments.

·        Focusing on Key Corridors: Corridors served by Bus Rapid Transit (BRT) benefit significantly from TSP systems.

Challenges and Solutions

While TSP can improve public transportation efficiency, it can also cause delays for other traffic. Authorities must decide how frequently and under what conditions TSP should be used. Overuse of TSP can prevent traffic lights from returning to their default schedules, leading to broader traffic delays. Therefore, a balanced approach is necessary to ensure that the benefits to public transport do not excessively disrupt other traffic.

Requirements for Effective TSP Implementation

·        System Configuration: Led by transport and signal agencies, a well-planned system configuration is crucial.

·        Guidelines: Clear guidelines on TSP operation rules are necessary.

·        Equipment Details: Provide detailed information on equipment and its implementation to ensure system compatibility across all jurisdictions.

·        Consideration of Factors: Geometric and operational factors such as traffic volume, capacity, signal intervals, and signal cycle length must be considered.

Implementing TSP can significantly enhance public transportation efficiency and reliability, reducing vehicle wait times at red lights and improving overall travel times. With careful planning and execution, TSP can provide substantial benefits to urban transit systems. For more visit https://www.emtracsystems.com
