MONITORING TRAFFIC SIGNAL PREEMPTION
First Claim
1. A method for monitoring traffic signal preemption at one or more intersections, comprising:
- displaying a road map with a computer system, wherein the road map includes a plurality of roads and intersections;
periodically transmitting preemption data from at least one preemption controller at a respective intersection to the computer system;
displaying at least one traffic signal icon proximate the respective intersection on the road map; and
in response to receiving the preemption data, updating the road map to include 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.

Abstract
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.
