Low Friction Safety System for a Personal Vehicle Guideway
First Claim
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 on-board 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; and
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 provide a secondary guidance for vehicles;
wherein front wheels of the transport vehicles, by virtue of the angle of the guide curbs, provide a region of contact to vehicle wheels only at a relatively thin line near the outside diameter of each wheel, and wherein the guide curbs or the front wheels at the region of contact, or both, are surfaced with a low-friction material.

Abstract
A transit system has an elevated controlled roadway system, a plurality of powered transport vehicles with steerable front wheels having a common width dimension, and both manual controls and an on-board computer (OBC) system for control on the elevated roadway, a master computer system communicating with the OBCs, enabled thereby to determine location of transport vehicles and to control velocity of the transport vehicles, and outwardly-angled guide curbs along opposite sides of the roadway surface, and spaced apart at a dimension larger than the common width dimension. The front wheels of the transport vehicles, by virtue of the angle of the guide curbs, provide a region of contact to vehicle wheels only at a relatively thin line near the outside diameter of each wheel, and wherein the guide curbs or the front wheels at the region of contact, or both, are surfaced with a low-friction material.
