Abstract

A hierarchical traffic control system is disclosed. The traffic control system comprises a primary controller. The primary controller receives information about traffic in an area. The system further includes a plurality of subsidiary controllers. The subsidiary controllers provide information to and receive information from the primary controller. Each of the plurality of subsidiary controllers is associated with a cell within the area. Each of the subsidiary controllers receives and provides information to at least one vehicle concerning traffic conditions within its associated cell. The primary controller and each of the subsidiary controllers are capable of negotiating a change in the flow of traffic based upon traffic conditions. In this system, at least one vehicle within the traffic includes a third-party permission for operation.

Claims

1. A traffic control system comprising:

a primary controller, the primary controller for receiving information about traffic in an area; and

a plurality of subsidiary controllers for providing information to and receiving information from the primary controller, each of the plurality of subsidiary controllers being associated with a cell within the area;

each of the subsidiary controllers receiving and providing information to at least one vehicle concerning traffic conditions within its associated cell, wherein the primary controller and each of the subsidiary controllers are capable of negotiating a change in the flow of traffic based upon traffic conditions, wherein at least one vehicle within the traffic includes a third-party permission for operation.

2. The traffic control system of claim 1 wherein each of the subsidiary traffic controllers can determine position of a vehicle in its associated cell.

3. The traffic control system of claim 1 wherein each of the subsidiary controllers can change the route of a vehicle based upon communications with the primary controller.

4. The traffic control system of claim 3 wherein the communications within the primary controller includes roles and permissions for the vehicle.

5. The traffic control system of claim 4 wherein the vehicle automatically sends information to one of the subsidiary controllers concerning location, vehicle operation and vehicle information.

6. The traffic control system of claim 5 wherein the vehicle includes a GPS location system, a voice communication system, and at least one vehicle operation system, wherein information concerning the vehicle operation can be communicated from any combination of the GPS location, the voice communication system and the at least one vehicle operation system.

7. The traffic control system of claim 6 wherein the vehicle operation system comprises an anti-lock braking system.

8. The traffic control system of claim 6 wherein the vehicle operation system comprises a suspension system.

9. The traffic control system of claim 6 wherein the vehicle operation system comprises a fuel indication system.

10. The traffic control system of claim 1 wherein the third-party permission is provided by a trip plan for the vehicle to the traffic control system.

11. The traffic control system of claim 1 wherein if the permission is violated an appropriate action is taken by the traffic control system.

12. The traffic control system of claim 11 wherein the appropriate action could be any combination of rendering the at least one vehicle inoperative, notifying an agency or notifying entity responsible for the at least one vehicle.

13. A traffic control system comprising:

a primary controller, the primary controller for receiving information about traffic in an area, the primary controller including a first plurality of participant objects; and

a plurality of subsidiary controllers for providing information to and receiving information from the primary controller, each of the plurality of subsidiary controllers including a second plurality of participant objects, each of the plurality of subsidiary controllers being associated with a cell within the area, each cell being represented as a plurality of segment objects;

each of the subsidiary controllers receiving and providing information to at least one vehicle concerning traffic conditions within its associated cell, wherein the primary controller and each of the subsidiary controllers are capable of negotiating a change in the flow of traffic based upon traffic conditions, wherein at least one vehicle includes a third-party permission for operation and third-party permission is communicated to a participant object within one of the controllers.

14. The traffic control system of claim 13 wherein each of the subsidiary traffic controllers can determine position of a vehicle in its associated cell via at least one of the participant objects.

15. The traffic control system of claim 13 wherein each of the subsidiary controllers can change the route of a vehicle based upon updating a participant object by a primary controller.

16. The traffic control system of claim 15 wherein the communications within the primary controller includes roles and permissions for the vehicle.

17. The traffic control system of claim 16 wherein the vehicle automatically sends information to one of the participant objects within a subsidiary controller concerning location, vehicle operation and vehicle information.

18. The traffic control system of claim 17 wherein the vehicle includes a GPS location system, a voice communication system, and at least one vehicle operation system, wherein information concerning the vehicle operation can be communicated from any combination of the GPS location, the voice communication system and the at least one vehicle operation system.

19. The traffic control system of claim 18 wherein the vehicle operation system comprises an anti-lock braking system.

20. The traffic control system of claim 18 wherein the vehicle operation system comprises a suspension system.

21. The traffic control system of claim 18 wherein the vehicle operation system comprises a fuel indication system.

22. The traffic control system of claim 13 wherein the third-party permission is provided by a trip plan for the vehicle to a participating object within the traffic control system.

23. The traffic control system of claim 13 wherein if the permission is violated an appropriate action is taken by the traffic control system.

24. The traffic control system of claim 23 wherein the appropriate action could be any combination of rendering the at least one vehicle inoperative via the vehicle operation system, notifying an agency via a controller or notifying an entity responsible for the at least one vehicle via a controller.
