1. A system for moving a plurality of vehicles in a single lane of traffic on a roadway through a control zone which comprises:

  • a sensor for determining an approach of each vehicle to a threshold of the control zone;

    a plurality of signals wherein each signal moves at a distance “

    s”

    ahead of a corresponding one of said vehicles through the control zone for managing the movement of the corresponding vehicle at a speed “

    v”

    determined for each signal;

    a control protocol established for each vehicle entering the control zone wherein the control protocol establishes and continuously updates a safe stopping distance “

    sd” and

    a distance “

    d”

    between consecutive ones of said signals based on the length “

    l”

    of the corresponding vehicle and the distance “

    s”

    ;

    a regulator for monitoring the distance “

    s”

    between each vehicle and the corresponding signal; and

    a computer connected to the sensor for initiating the control protocol for each vehicle at the threshold, wherein the computer establishes the speed “

    v”

    for moving each signal, and further wherein the computer is connected to the regulator to create an alarm when the distance “

    s”

    creates a predetermined condition.
