Personal transportation system
First Claim
1. A transportation system for moving passengers and freight, comprising:
- a track network, said track comprising a pair of side rails and a central rail;
a plurality of vehicles, each said vehicle having a body with a width for one passenger seat, a plurality of wheels engaged on said side rails for supporting the vehicle, a plurality of guiding wheels engaged on said central rail for centering the vehicle on the track, an identification means for providing vehicle identification information, a distance sensor for measuring distance and speed of an object in front of the vehicle, a wireless communication means, driving and braking means, and a vehicle control system connected with said distance sensor and said driving and braking means for controlling the driving and braking of the vehicle;
a plurality of stops and stations on the side tracks off the main lines of said track network for loading and unloading, each stop and each station having an access notification device;
a plurality of wayside control systems, each having a computer system, a means for detecting said vehicle identification information of said identification means of the vehicle, and a means for controlling switches on said track network;
a central control system having a computer system for user registration, vehicle registration, and controlling the traffic flow;
a communication network connecting said central control system, said wayside control system, said vehicle control system, and said access notification system;
whereby a passenger can enter said vehicle at a station or stop and move directly from origin to destination.

Abstract
An autonomous personal transportation system for moving passengers and light freights is constructed with a track network and small vehicles on the track network. There are a number of stations and stops for loading and unloading on side tracks off the mainline of the track network. The vehicle width is limited to a dimension for one seat. The vehicles can be coupled statically or dynamically to form a train. The track has side rails for the rigid wheels of the vehicle and a central rail for centering the vehicle on the guideway and providing additional acceleration and braking capability. The control system for the movement of vehicles is divided into three levels: the central control system, the wayside control system and the vehicle control system.

9. A method of controlling movement of a vehicle through a track network having a plurality of merging points, diverging points, stations and stops, from an origin to a destination, comprising
assigning a vehicle identification number to said vehicle; -
providing means for storing said vehicle identification number in said vehicle; providing a distance sensor means to said vehicle for avoiding collisions; setting up a plurality of control points, each before said merging point, diverging point, station and stop; dividing said track network into a plurality of segments between said control points; providing a wayside control system at each said control point, each said wayside control system has a means for detecting said vehicle identification number and a means for switch operation; providing a vehicle control system to said vehicle for controlling the operation of said vehicle, said vehicle control system operatively connected to said distance sensor means; providing a communication network for connecting said central control system with a plurality of said wayside control system and said vehicle control system; planning the direction and speed profile of said vehicles before said control points by said central control system; informing the direction of said vehicle to said wayside control system and informing the speed profile information to said vehicle control system through said communication network; detecting said vehicle identification number of said vehicle by said wayside control system; implementing said direction of said vehicle by said wayside control system; implementing said speed profile for said segment of said track network and avoiding collision according to information from said distance sensor means by said vehicle control system; whereby the infrastructure cost of said track network and the communication demand in said communication network are reduced.
