Abstract

A transportation system for moving passengers comprising a plurality of terminals interconnected by a track network, upon which are supported a plurality of independent and individual self-guided vehicles. Each terminal has a plurality of Automated Ticketing machines (ATMs) for automated bank account or credit line debiting and for producing passenger tickets with coded destination information. Each vehicle has a body for carrying up to two passengers, wheels for supporting and moving the vehicle, driving and braking means, a wireless data link, and a Vehicle Control and Data Processing Computer (VCDPC). Each VCDPC reads the coded destination information on a passengr'"'"'s ticket, computes a travel route, controls the driving and braking means, and stores operating data. Each vehicle also has mounted thereto an Identification and scanning Device (ISD), carrying vehicle identity information and operating under the control of the VCDPC. Other ISDs are positioned at a number of fixed locations in the track network and carry unique location identity information. Vehicle mounted ISDs are capable of detecting and reading the ISDs at each fixed location when in close proximity thereto, thereby providing vehicle location and direction of movement information to the VCDPC. A Master Contorl and Data Processing Computer (MCDPC), location at a fixed fixed, has a wireless data link to access all VCDPCs to obtain the travel route and current location of each vehicle and to issue vehicle commands. The MCDPC is also interconnected with each ISD at a fixed location in the track network in order to obtain backup data revealing the location of all vehicles. The MCDPC is also interconnected with each ATM at each terminal to obtain passenger travel demand data, to computer an optimal travel route for all vehicles in use, and to route vehicles that are not currently is use to terminals having higher passenger demand.

Claims

1. A transportation system for moving passengers, comprising:

a plurality of terminals for providing access of said passengers to said transportation system, each said terminal having at least one automated ticketing machines (ATM) for producing passenger tickets having a coded destination information;

the terminals being interconnected by;

a track network upon which are supported and guided;

a plurality of vehicles, each said vehicle having a body for carrying up to two said passengers, wheels for supporting and moving the vehicle, a means of driving and braking said wheels, a wireless data link, and a vehicle control and data processing computer (VCDPC) for reading said coded destination information, for computing a proposed travel route, for controlling said means for driving and braking, and for storing operating data, the vehicles all moving individually over the track network;

a plurality of identification and scanning devices (ISD), one of the ISD being mounted on each said vehicle for providing vehicle identity information under the control of said VCDPC, one of the ISD being positioned at each one of a plurality of fixed locations along said track network for providing location identity information, each said ISD being capable of detecting any other said ISD when in close proximity thereto, thereby providing a current location and direction of movement information to said VCDPC; and

a master control and data processing computer (MCDPC) located at a fixed site, the MCDPC having said wireless data link to access all said VCDPC to obtain the proposed travel route and the current location of each said vehicle, the MCDPC being interconnected with the ISD which are at the fixed locations, to obtain location data of each said vehicle, the MCDPC being interconnected with all said ATM to obtain passenger travel demand data, to compute an optimal travel route for each said vehicle;

whereby at least one said passenger may enter said transportation system through any said terminal, purchase said ticket from said ATM after indicating a desired destination, enter one said vehicle, input said destination information into said VCDPC, and wait while said vehicle transports said passenger to said destination over said track network.

2. The transportation system of claim 1 wherein said means of driving and braking further include a means for velocity control enabling all said vehicles that are in use to move at a previously established common velocity.

3. The transportation system of claim 1 wherein said VCDPC further includes a means for passenger information display and a means for passenger control to change said destination.

4. The transportation system of claim 3 wherein said means for passenger information display includes a liquid crystal display device.

5. The transportation system of claim 1 wherein said identification and scanning devices use an optical method of scanning.

6. The transportation system of claim 1 wherein said vehicles each carry a radar detection means for avoiding collision with another said vehicle by detecting vehicle spacing by measuring the time for a radar burst to travel between said vehicles, and closing rate by calculating the first derivative of the vehicle spacing with respect to time.

7. The transportation system of claim 1 wherein said ATM has means for automated bank account or credit card debiting.
