Abstract
A traffic control system includes a traffic planner that communicates with a cellular telephone system to help manage the flow of traffic, especially when emergency vehicles are rushing to a destination. The cellular communication system determines the location of the emergency vehicle, and relays the location to the traffic planner. The traffic planner, in turn, controls the traffic lights to clear the traffic along the route traveled by the emergency vehicle. The cellular communication system can also determine the location of any vehicle carrying a subscriber unit and provide navigational information that helps the vehicle arrive at its destination. The navigational information includes road maps and directions.
