1. An interactive vehicle traffic flow control system comprising:

  • a) At least one vehicle, said vehicle having a method of uniquely and remotely identifying said vehicle'"'"'s real time identity and location;

    b) At least one controllable traffic signal;

    c) At least one roadside equipment to capture said vehicle'"'"'s method of uniquely and remotely identifying said vehicle'"'"'s real time identity and location, wherein said roadside equipment is in data communication with said vehicle;

    d) At least one adaptive signal processor connected to said roadside equipment to process said vehicle'"'"'s method of uniquely and remotely identifying said vehicle'"'"'s real time identity and location, wherein said adaptive signal processor calculates the optimum signal phase change time for said controllable traffic signal based on the unique identity and location of said vehicle; and

    e) At least one signal controller, connected to said adaptive signal processor, and connected to said traffic signal, wherein said signal controller responds to instructions from said adaptive signal processor and changes said phase timing in said traffic signal so as to minimize traffic delays.
