Methods And Software For Managing Vehicle Priority In A Self-Organizing Traffic Control System
First Claim
1. A machine-readable storage medium containing machine-executable instructions for performing a method of managing vehicle priority proximate to a potential travel-priority conflict zone, the method being executed in a dynamic traffic control system, said machine-executable instructions comprising:
- a first set of machine-executable instructions for communicating with a first component of the dynamic traffic control system located on-board a vehicle proximate to the potential travel-priority conflict zone so as to establish a dynamic traffic control plan for avoiding a travel-priority conflict in the potential travel-priority conflict zone;
a second set of machine-executable instructions for coordinating with the first component of the dynamic traffic control system via said communicating to elect a dynamic traffic controller as a temporary coordinator vehicle responsible for temporarily coordinating the dynamic traffic control plan;
a third set of machine-executable instructions for receiving a priority-request message from a priority vehicle;
a fourth set of machine-executable instructions for determining a travel direction of the priority vehicle;
a fifth set of machine-executable instructions for comparing the travel direction of the priority vehicle to a travel direction of a non-priority vehicle proximate to the potential travel-priority conflict zone;
a sixth set of machine-executable instructions for transmitting a priority-granted message to the priority vehicle when the travel direction of the priority vehicle and the travel direction of the non-priority vehicle proximate to the potential travel-priority conflict zone differ; and
a seventh set of machine-executable instructions for providing traffic control instructions to an operator of the priority vehicle via a visual or audio indication produced in the priority vehicle as a function of the priority-granted message.

Abstract
Methods and software for managing vehicle priority proximate to a potential travel-priority conflict zone, such as a roadway intersection, where travel conflicts, such as crossing traffic, can arise. Coordination involves forming an ad-hoc network in a region containing the conflict zone using, for example, vehicle-to-vehicle communications and developing a dynamic traffic control plan based on information about vehicles approaching the conflict zone. Instructions based on the dynamic traffic control plan are communicated to devices aboard vehicles in the ad-hoc network, which display one or more virtual traffic signals to the operators of the vehicles and/or control the vehicles (for example, in autonomous vehicles) in accordance with the dynamic traffic control plan, which may account for a priority level associated with one or more of the vehicles.

-
a first set of machine-executable instructions for communicating with a first component of the dynamic traffic control system located on-board a vehicle proximate to the potential travel-priority conflict zone so as to establish a dynamic traffic control plan for avoiding a travel-priority conflict in the potential travel-priority conflict zone; a second set of machine-executable instructions for coordinating with the first component of the dynamic traffic control system via said communicating to elect a dynamic traffic controller as a temporary coordinator vehicle responsible for temporarily coordinating the dynamic traffic control plan; a third set of machine-executable instructions for receiving a priority-request message from a priority vehicle; a fourth set of machine-executable instructions for determining a travel direction of the priority vehicle; a fifth set of machine-executable instructions for comparing the travel direction of the priority vehicle to a travel direction of a non-priority vehicle proximate to the potential travel-priority conflict zone; a sixth set of machine-executable instructions for transmitting a priority-granted message to the priority vehicle when the travel direction of the priority vehicle and the travel direction of the non-priority vehicle proximate to the potential travel-priority conflict zone differ; and a seventh set of machine-executable instructions for providing traffic control instructions to an operator of the priority vehicle via a visual or audio indication produced in the priority vehicle as a function of the priority-granted message. - View Dependent Claims (2, 3, 4, 5)
