Hierarchical traffic control system
First Claim
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; and
wherein each of the subsidiary traffic controllers can determine position of a vehicle in its associated cell wherein at least one of the subsidiary controllers can interact with another of the subsidiary controllers.

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 a method and system in accordance with the present invention, each of the subsidiary controllers monitors a finite portion of the route and can be in direct contact with the vehicles. The primary controller receives and transmits information to and from the traffic controller and allows for an overall view of the route to be understood. Accordingly, through the use of the hierarchical traffic control system, traffic is controlled from cell to cell more accurately and can be controlled over a wide traffic span.
