Approaches for prioritizing multiple candidates (312) for preemption of a traffic signal phase at an intersection are disclosed. Light signals transmitted from light-signaling (108) vehicles approaching an intersection encode priority codes using a first set of values. Radio signals from radio-signaling (110) vehicles approaching the intersection encode priority codes using a second set of values. A set of preemption candidates is determined (210) from the light and radio signals, as well as from network-based (134) requests, and a respective relative priority of each preemption candidate based on the priority code of each preemption candidate is determined (440, 444). A request is output (448) for preemption of the traffic signal phase for a preemption candidate having a highest priority. |
