Defining approach maps for traffic signal preemption controllers
First Claim
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.

Abstract
Methods and systems for creating an approach map for a traffic signal preemption controller. A road map is displayed, and 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 is displayed. The one road represents an approach road to an intersection having the preemption controller. First segment location data that describes a first geographical area bounded by the first segment are determined 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. The first segment location data are stored in association with the approach map for the preemption controller. 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.

10. A system for managing geographically dispersed traffic signal preemption control equipment, the traffic signal preemption control equipment including traffic signal preemption controllers and vehicle control units, comprising:
-
at least one processor; a memory arrangement coupled to the processor, wherein the memory arrangement is configured with instructions for execution by the processor, wherein execution of the instructions by the at least one processor causes the at least one processor to perform operations including;
displaying a road map, 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 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An article of manufacture, comprising:
-
a non-transitory processor-readable storage device configured with instructions for managing geographically dispersed traffic signal preemption control equipment, the traffic signal preemption control equipment including traffic signal preemption controllers and vehicle control units, wherein in executing the instructions by one or more processors causes the one or more processors to perform operations including; displaying a road map, 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.
