Field of view traffic signal preemption

摘要

Approaches for issuing preemption requests. The boundaries of a geo-window are repeatedly determined based on locations and headings of a vehicle as the vehicle is traveling along a roadway. The methods and systems determine whether or not any one of a plurality of intersections is located within the boundaries of the geo-window in response to changed boundaries of the geo-window. In response to determining that one of the plurality of intersections is located within the boundaries of the geo-window, a preemption request is transmitted from the vehicle to an intersection controller at the one of the plurality of intersections.

主权项

1. A method for issuing preemption requests, comprising:
determining, by an on-vehicle circuit arrangement, a location and a heading of a vehicle; calculating, by a processor of the on-vehicle circuit arrangement, coordinates that define boundaries of a geo-window in response to the determined location and heading; determining, by the on-vehicle circuit arrangement, whether or not any one of a plurality of intersections is located within the boundaries of the geo-window; in response to determining that one of the plurality of intersections is located within the boundaries of the geo-window, transmitting a preemption request from the vehicle to an intersection controller at the one of the plurality of intersections.
