Abstract
Approaches for prioritizing multiple candidates for preemption of a traffic signal phase at an intersection are disclosed. Light signals transmitted from light-signaling vehicles approaching an intersection encode priority codes using a first set of values. Radio signals from radio-signaling vehicles approaching the intersection encode priority codes using a second set of values. A set of preemption candidates is determined from the light and radio signals, as well as from network-based requests, and a respective relative priority of each preemption candidate based on the priority code of each preemption candidate is determined. A request output for preemption of the traffic signal phase for a preemption candidate having a highest priority.
