ABSTRACT:
A mass transit system includes a plurality of pedestal-mounted rings which provide a support through which a vehicle travels. The pedestals are spaced apart on the ground, but no rail or connecting structure on or above ground is required. An underground conduit carries electrical and communications cable that connects the pedestals together. The rings include a plurality of rollers to drive, guide and stabilize the vehicle at lower speeds. For higher speeds flywheels are mounted on the pedestals. The flywheels are preferably driven by an electrical motor, which engages a friction or clutch plate on the vehicle separate from the rings. The friction plate or linear clutch is mounted separate from the rings on the vehicle and is lowered to engage and disengage the flywheel. The flywheel is also mounted on a shock absorber to smooth the travel of the vehicle.
