Approaches for monitoring traffic signal preemption at one or more intersections. According to one embodiment, a road map that includes a plurality of roads and intersections is displayed with a computer system. Preemption data periodically received by the computer system from at least one preemption controller at a respective intersection is used to update the road map. In response to the preemption data, the road map is updated to include a traffic signal icon at the respective intersection and a vehicle icon at a location on the map corresponding to a location of a vehicle transmitting a preemption request as indicated by the preemption data.
