<p>A transit system employing multiple modes of operation. The system includes a guideway (48) having a portion over which a vehicle (26) traverses from one location to another, the traverse portion having a longitudinally-extending slot formed generally centrally therewithin. The guideway also includes an entry ramp (22) which directs a traction drive wheel stem (78) to centrally position the vehicle on the guideway. The system also includes a vehicle (26) which is configured for travel over both a roadway and the guideway. The vehicle includes a chassis supported by a plurality of motive wheels. The chassis mounts a stem (78) for pivoting between an upper, retracted position and a lower, extended position. The stem (78) mounts, at its lower end, a traction drive wheel (82) which engages an undersurface of the guideway to accomplish movement of the vehicle (26) during the guideway mode of operation. Means are provided for both driving the motive wheels, during the roadway mode of operation, and the traction drive wheel, during the guideway mode of operation. An on-board computer controls guidance of the vehicle over the guideway system. <IMAGE></p> |
