Abstract

A computer-implemented method and system for vehicular traffic control and vehicle routing includes receiving a request for a best route, at a central system. The request including a current location and a destination from a requesting vehicle. Travel factors from the current location to the destination are determined. The travel factors include road availability, traffic conditions, and real time feedback, using the central system in response to receiving the request. The best route is determined for the requesting vehicle from the current location to the destination based on the travel factors, and real time feedback of the traffic conditions. The method and system includes initiating a plurality of traffic control actions along the route for the requesting vehicle. The traffic control actions are initiated along the route simultaneously and in concert with the requesting vehicle to clear the best route for the requesting vehicle to travel unobstructed to the destination.
