What does "signal priority" refer to?

Signal priority refers to a system that adjusts signal timing based on specific vehicle types, particularly emergency vehicles or public transit. This approach is designed to enhance the flow of traffic and improve the efficiency of public transport and emergency response times. When certain vehicles, like buses or fire trucks, approach an intersection, the signal priority system detects them and adjusts the traffic signal accordingly, often giving priority to these vehicles to ensure they can pass through intersections quickly and safely.

The focus is on improving the overall traffic management system, making it more responsive to the needs of essential vehicles within the traffic flow. This concept is crucial in urban planning and traffic management, where the goal is often to keep traffic moving efficiently while prioritizing safety and quick response times for emergency services.
