Abstract:
1. A method for creating an approach map for a traffic signal preemption controller, comprising: displaying a road map with a computer system, wherein the road map represents a plurality of roads and intersections; displaying in response to user input for instantiating a first segment of an approach map, a first instance of a graphical object overlaying one of the plurality of roads, the one road representing an approach road to an intersection having the preemption controller; determining first segment location data descriptive of a first geographical area bounded by the first segment from size and placement of the first instance of the graphical object on the road map and from location data associated with the one road; and storing in a non-transitory processor-readable storage device, the first segment location data in association with the approach map for the preemption controller, wherein the preemption controller, once configured with the first segment location data, initiates traffic signal preemption in response to a preemption request transmitted from within the first geographical area described by the first segment location data.
