Traffic signal preemption for emergency vehicles is a connected vehicle (CV) application enabling the rapid movement of emergency vehicles on arterials. This study describes a signal control strategy that reduces emergency vehicle response time (EVRT).

Methodology

EVRT is expected to be reduced utilizing vehicle-to-infrastructure (V2I) communication, IEEE 802.11 beaconing, and predicted queue length to adaptively adjust signals to provide an early green at the right time so the queue at the downstream intersections can be served in time for the arrival of the emergency vehicle. The strategy is tested in a microscopic traffic simulation using the City of Toronto network and 150,000 vehicles.
