ABSTRACT:
An automatic traffic control method and device includes an endless conveyor which is located along a predetermined length of a road for carrying a vehicle travelling in a first direction, the conveyor capable of moving in a second direction opposite to the first direction, thereby reducing the vehicle's virtual speed. A regenerative braking device engages the conveyor to oppose the conveyor movement. The braking device can also be used to reclaim kinetic energy generated by a decelerated vehicle. A sensor senses the vehicle speed and provides a signal to modulate the braking device. A receiver-decoder receives transmitted command signals to modulate the sensor signal, thereby to remotely set a desirable speed limit and ensure the passing vehicles obey the speed limit.
