A traffic control preemption system uses data received from a global positioning system (GPS) to determine whether a vehicle issuing a preemption request is within an allowed approach of an intersection. GPS signals are received and processed by the vehicle module to generate vehicle data, including the vehicle\s position, heading and velocity. The vehicle data is transmitted via radio transmission or some other medium. Each intersection has an associated intersection module which, if within range of the vehicle\s transmitting equipment, compares the received vehicle data with a preprogrammed map of allowed approaches to the intersection. If the vehicle data sufficiently matches the map of allowed approaches, the vehicle\s preemption request is forwarded to the intersection controller to appropriately control the phase of the traffic signal at the intersection.
A system for determining whether a vehicle having an associated vehicle path is within an allowed approach of a location, comprising: navigation means, associated with the vehicle, for generating vehicle data at periodic intervals along the vehicle path, wherein the vehicle data includes vehicle pos
A system for determining whether a vehicle having an associated vehicle path is within an allowed approach of a location, comprising: navigation means, associated with the vehicle, for generating vehicle data at periodic intervals along the vehicle path, wherein the vehicle data includes vehicle position data; means for transmitting the vehicle data; means, associated with the location, for receiving the vehicle data; mapping means, associated with the location, for storing a plurality of positions corresponding to allowed approaches to the location and providing therefrom a map of allowed approaches; evaluation means for comparing the vehicle data to the map of allowed approaches to determine whether the vehicle path is within an allowed approach.
