Traffic Signal Preemption for Emergency Vehicles is a critical technology designed to improve emergency response times and enhance roadway safety. Unlike Transit Signal Priority (TSP), which provides conditional signal priority for transit vehicles while maintaining standard traffic signal operations, Traffic Signal Preemption for Emergency Vehicles overrides regular signal cycles to grant immediate green lights to emergency responders. This ensures that fire trucks, ambulances, and police vehicles can navigate intersections swiftly and safely, reducing delays and improving emergency response efficiency. Traffic Signal Preemption for Emergency Vehicles works by utilizing advanced communication systems such as GPS, optical, and cellular-based technologies. When an emergency vehicle is en route to an incident, the preemption system detects its approach and modifies traffic signals accordingly, allowing the vehicle to pass through intersections without stopping. This real-time intervention significantly reduces travel time, minimizes congestion, and enhances overall public safety.
