Abstract

A unique transit system incorporates at least one internally powered, wheeled, transport vehicle having both manual controls enabling a user to drive the vehicle on a surface street and an on-board computer (OBC) system enabling software control of at least vehicle steering and velocity. A controlled roadway system having a roadway surface upon which the transport vehicle runs on its internal power on the same wheels as on surface streets is provided as well. On surface streets off the controlled roadway the manual controls are active, and on the controlled roadway the software controls are active. Manual or computer control depends on whether the vehicle is on the controlled roadway or surface streets. The OBC communicates with a Master computer for the controlled roadway, providing a range of functions. The transport vehicles operate at a fixed and constant speed on the controlled roadway system.

Claims

1. A transit system comprising:

a plurality of internally powered, wheeled, transport vehicles, each individual vehicle having both manual controls enabling a user to drive the vehicle on a surface street and an on-board computer (OBC) system enabling software control of at least vehicle steering and velocity;

a Master computer system enabled to establish two-way communication with the OBC on each vehicle; and

a controlled roadway system having a roadway surface upon which the transport vehicle runs on its internal power on the same wheels as on surface streets;

wherein, on surface streets off the controlled roadway the manual controls are active, and on the controlled roadway the software controls are active, and the Master computer system maps the controlled roadway into fixed length virtual packets traveling at a constant speed, identifies the packets uniquely, identifies all compatible transport vehicles uniquely, relates the virtual packets to corresponding vehicles and controls transport vehicles to occupy corresponding virtual packets.

2. The transit system of claim 1 wherein selection of on-board computer control is automatically triggered by entrance to the controlled roadway system.

3. The transit system of claim 1 wherein the Master computer system controls speed of transport vehicles on the controlled roadway, via the two way communication with the OBC, in a manner to prevent any two transport vehicles occupying the same physical space.

4. The transit system of claim 1 further comprising access stations at predetermined positions along the controlled roadway, the access stations connecting to the controlled roadway by entrance and exit ramps such that transport vehicles may accelerate and join the controlled roadway via entrance ramps, and may also exit the controlled roadway via exit ramps and decelerate.

5. The transit system of claim 1 wherein the controlled roadway comprises side-by-side lanes, for opposite directions of travel.

6. The transit system of claim 1 further comprising an enclosure covering substantial portions of travel lanes of the controlled roadway, such that air within the enclosure is caused to move in the direction of transport vehicle travel, therefore reducing air friction impeding progress of vehicles moving on the roadway.

7. The transit system of claim 6 further comprising at least one air pump mechanism for moving air within the enclosure in the direction of vehicle travel.

8. The transit system of claim 1 wherein the two-way communication is by a wireless network.

9. The transit system of claim 8 wherein the wireless network covers the entire controlled roadway system and extends in range to cover a substantial portion of the range of compatible transit vehicles on surface streets, such that the Master computer may communicate with transit vehicle OBCs both on and off the controlled roadway system.

10. The transit system of claim 1 wherein the Master computer system is Internet-connected, allowing users of compatible transit vehicles to access and interact with Master computer functions by Internet connection with an Internet appliance.

11. The transit system of claim 10 wherein Master computer functions include at least reserving space in specific time slots for travel on the controlled roadway system.

12. The transit system of claim 1 wherein the transit vehicles are electrical vehicles (EVs).

13. A wheeled personal transport vehicle (PV), comprising:

an on-board power plant;

manual controls comprising at least steering and speed controls enabling an operator to operate the vehicle on surface streets;

an on-board computer (OBC) system enabled to operate at least the steering and speed controls by software; and

an exclusive selection mechanism for selecting either manual or OBC control; and

a software component in the OBC on each vehicle enabled to establish two-way communication with a master computer system;

wherein the PV is controlled by the OBC according to information received from the master computer which includes mapping the controlled roadway into virtual packets, identifies the packets uniquely, identifies all compatible transport vehicles uniquely, and controls transport vehicles to occupy corresponding virtual packets.

14. The PV of claim 13 wherein the OBC comprises a wireless communication link to an off-board Master computer system.

15. The PV of claim 14 wherein the Master computer system selects between OBC and manual control for the PV.

16. The PV of claim 13 wherein the manual controls operate through the OBC by providing input to the OBC which in turn drives steering and speed control mechanisms.

17. The PV of claim 13 further comprising proximity sensors sensing proximity of structures to either side of the direction of travel of the PV, the proximity sensors providing input to the OBC, which uses the input in conjunction with software to steer the PV between the structures to either side of the PV.

18. The PV of claim 17 further comprising proximity sensors facing in the direction of travel of the PV and providing input to the OBC used for adjusting speed of the PV to adjust proximity of the PV to a second PV moving in the same direction of travel.

19. The PV of claim 17 comprising software executing on the OBC using input from the side-facing proximity sensors and OBC steering control to cause the PV to selectively follow a structure to one side or the other of the direction of travel of the PV.

20. The PV of claim 13 wherein the power plant is a battery-enabled electrical power plant, and the PV is therefore an electrical vehicle (EV).

21. The PV of claim 14 further comprising a user interface enabling an operator to interact with functions provided by the off-board computer system.

22. The PV of claim 21 wherein the functions include at least logging and reserving travel time and space on a compatible controlled roadway system.
