Abstract
A system and method for moving vehicular traffic in a single lane through a control zone requires creation of a control protocol. The protocol establishes a spacing distance “s” and a speed “v” for each vehicle in the control zone. A computer then controls movement of a visible signal through the control zone in accordance with the established protocol. Electronic regulators monitor the distance “s” between the signal and the vehicle, and the system alarms when “s” becomes greater than a predetermined distance “d”.
