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 the present invention, at least one vehicle includes roles and permission sets. The traffic control system can then determine the appropriate route for the vehicle based upon the roles and permission sets.

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 includes roles and permission sets, wherein the traffic control system can determine the appropriate route for the at least one vehicle based upon the roles and permission sets.

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 wireless 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 roles and permission sets changeable based upon circumstances.

11. The traffic control system of claim 1 wherein the roles and permission sets are provided by a trip plan of the vehicle being submitted to the primary controller.

12. The method of claim 6 wherein the vehicle can negotiate a permission for a cell based upon the GPS location system, the at least one vehicle operation system and the wireless communication system.

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 roles and permission sets, wherein the traffic control system can determine the appropriate the at least one vehicle based upon the roles and permission sets and the first and second plurality of participant objects.

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 the second plurality of 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 communications with the primary controller.

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

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

18. The traffic control system of claim 17 wherein the vehicle includes a GPS location system, a wireless 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 roles and permission sets changeable based upon circumstances.

23. The traffic control system of claim 13 wherein the roles and permission sets are provided by a trip plan of the vehicle being submitted to a participant object of the primary controller.

24. The method of claim 18 wherein the vehicle can negotiate a permission for a cell based upon the GPS location system, the at least one vehicle operation system and the wireless communication system.
