Abstract
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.
