ABSTRACT:
A roadway having a smooth road surface for automotive vehicles includes means for transmitting electric current through the road surface to electrically-operated vehicles travelling thereon. Each electrified traffic lane is provided with at least two spaced parallel electrical contact assemblies mounted with their top surfaces flush with the road surface and in position to be contacted one with a wheel on each side of the vehicle, with the contact assemblies each requiring a predetermined weight thereon to maintain electrical contact with the vehicle wheels. The vehicle employs electrically-conductive tires which roll on the electrically-conductive surface of the contact assemblies, and the current thus picked up is transmitted, through rolling-sliding contacts, conductors, etc. to controls for controlling the operation of the vehicle through individual wheel motors. The vehicle motors may be electric, but preferably are hydraulic or pneumatic motors which are driven as pumps or compressors during deceleration to thereby conserve energy, with the electric current driving a suitable pump or compressor to supply motive fluid through suitable pressure storage reservoir to the wheel motors during acceleration and normal driving. A battery pack is included for supplying current to operate the vehicle when the wheels are not on the contact assemblies, which battery pack is charged from current picked up from the roadway during normal operation or from special re-charging pads while the vehicle is parked.
