Abstract:
1. A transit system comprising: a controlled roadway system having a roadway surface substantially elevated above surface streets with on and off ramps communicating with the surface streets; a plurality of internally powered transport vehicles, each individual vehicle having a set of steerable front wheels having a common width dimension, and both manual controls enabling a user to operate the vehicle on the surface streets and an onboard computer (OBC) system enabling software control of at least vehicle steering and velocity while on the controlled roadway; a master computer system communicating with OBCs of individual ones of the transport vehicles while on the controlled roadway system, the master computer system enabled thereby to determine location of transport vehicles on the controlled roadway system, and to control velocity of the transport vehicles; a substantially horizontal track running the length of the roadway surface for supporting the wheels of the wheeled vehicle in motion; guide curbs along opposite sides of the roadway surface, the guide curbs each angled outwardly and spaced apart at a dimension larger than the common width dimension across the front wheels such that the transport vehicles may move freely between the guide curbs; and side curbs placed end-to-end along a top surface of the track and adjacent to the guide curbs extending in height up the surface of the guide curbs, and provide a secondary guidance for vehicles; wherein front wheels of the transport vehicles, due to the angle, provide a region of contact with the side curbs only at a lower half near the outside diameter of each wheel, and wherein the side curbs and the front wheels at the region of contact are surfaced with a low-friction material.
