Emergency Vehicle Network Delay (EVND) Phase 2

Traffic signal preemption temporarily alters normal signal time allocations in some manner. It gives preference to the movement of the preempting emergency vehicle (EV) through intersections, with limited regard to the effect the preemption may have on other vehicles on the facility. The character and significance of the effect depends on the geometric characteristics, the size and complexity of the facility, the traffic loading and traffic mix, the number and characteristics of the emergency vehicles requesting preemption, and the signal control methodology and the signal timing patterns in use. The objective of this project is to evaluate the impact that granting a signal preemption to an emergency vehicle has on subsequent emergency vehicle(s), when the vehicles are operating over a network of roads, where many or most of the intersections are signalized, and the signals are coordinated.
