A unique system would solve traffic, fossil-fuel depletion, and environmental problems. Dual-mode private and commercial vehicles would be manually driven on streets and automatically controlled on maglev guideways. Busses and freight vehicles without wheels or drivers also used. Proposed guideway speeds: 100kph in cities, and 325kph between cities. System would be safer and have much higher capacity than existing highways or proposed “smart car” systems. One-third meter clearance between cars to be achieved by linear synchronous-motor propulsion. Capacity of single 100kph guideway to equal that of twelve highway lanes, and one 325kph guideway would be equivalent to forty highway lanes.
