Abstract

A system includes one or more traffic guidance nodes (TGNs) and one or more mobile traffic navigating entities (TNEs). The traffic guidance nodes transmit updated information about the local traffic to the one or more mobile traffic navigating entities when the one or more mobile traffic navigating entities are within a range of the one or more traffic guidance nodes.

Claims

1. A system comprising:

one or more traffic guidance nodes comprising;

a traffic guidance indicator;

a receiver to receive information about local traffic;

one or more sensors to detect local traffic activity and generate information about local traffic activity;

a memory to store the information about local traffic; and

a transmitter to broadcast the information about local traffic; and

one or more mobile traffic navigating entities comprising;

a receiver to receive the information from the one or more traffic guidance nodes when the traffic navigating entity is within a proximity of the one or more traffic guidance nodes;

one or more sensors to detect local traffic activity and generate information about local traffic activity;

a memory to store the information about the local traffic activity;

a transmitter to send the information about the local traffic activity to other mobile traffic navigating entities and to the one or more traffic guidance nodes;

wherein the one or more traffic guidance nodes transmit updated information about the local traffic to the one or more mobile traffic navigating entities when the one or more mobile traffic navigating entities are within a range of the one or more traffic guidance nodes.

2. The system of claim 1 wherein the traffic guidance node comprises a structure for providing visual traffic directions to a driver.

3. The system of claim 2 wherein the structure is a traffic sign.

4. The system of claim 3 wherein the information about local traffic transmitted by the traffic guidance node corresponds to visual information provided by the traffic sign.

5. The system of claim 2 wherein the structure is a traffic signal.

6. The system of claim 5 wherein the local information transmitted by the traffic guidance node corresponds to a current state of the traffic signal.

7. The system of claim 1 wherein the transmitters are wireless transmitters.

8. The system of claim 1 wherein the sensors include one or more of:

a sensor for detecting presence of a traffic navigating entity;

a sensor for detecting a vehicle, a sensor for detecting speed of a traffic navigating entity, a sensor for detecting speed of a vehicle;

a sensor for detecting direction of a traffic navigating entity, a sensor for detecting direction of motor vehicles; and

a sensor for detecting presence of a pedestrian.

9. The system of claim 1 wherein the traffic navigating entity is a processing device that can be installed in a motor vehicle or carried by or attached to a pedestrian or bicyclist.

10. The system of claim 9 wherein at least one of the traffic navigating entities includes a human interface device to communicate the local traffic activity to a user of the processing device.

11. The system of claim 10 wherein the human interface device is a screen installed in a motor vehicle.

12. The system of claim 1 wherein the traffic navigating entities are configured to update the information about local traffic activity with the information about local traffic received from the traffic guidance nodes.

13. The system of claim 1 wherein the traffic guidance nodes are configured to update the information about local traffic with the information about local traffic activity received from the traffic navigating entities.

14. The system of claim 1 wherein the information about local traffic and/or the information about local traffic activity includes information about traffic hazards, a current state of a traffic signal, a future state of a traffic signal, traffic congestion;

proximity of emergency vehicles, or a combination thereof.

15. The system of claim 1 wherein at least one of the one or more traffic guidance nodes is stationary.

16. The system of claim 1 further comprising one or more computer centers comprising computing devices configured to coordinate communication between the traffic guidance nodes and the traffic navigating entities and to direct operation of one or more of the traffic guidance nodes.

17. The system of claim 1 wherein at least one of the one or more of the traffic guidance nodes is configured to alter a state of the traffic guidance indicator in response to detecting the local traffic and/or in response to a transmission received from a traffic navigating entity.

18. The system of claim 1 wherein the information broadcasted by the traffic guidance node includes a unique identifier of the traffic guidance node.

19. The system of claim 1 wherein the information broadcasted by the traffic guidance node includes a unique identifier of a traffic navigating entity.

20. The system of claim 1 wherein the information transmitted by the traffic navigating entity includes a unique identifier of the traffic navigating entity and/or a unique identifier of a traffic guidance node.

21. A system comprising:

one or more traffic guidance nodes comprising;

a traffic guidance indicator;

a receiver to receive information about local traffic;

one or more sensors to detect local traffic activity and generate information about local traffic activity;

a memory to store the information about local traffic; and

a transmitter to broadcast the information about local traffic; and

one or more mobile traffic navigating entities comprising;

a receiver to receive the information from the one or more traffic guidance nodes when the traffic navigating entity is within a proximity of the one or more traffic guidance nodes;

one or more sensors to detect local traffic activity and generate information about local traffic activity;

a memory to store the information about the local traffic activity; and

a transmitter to send the information about the local traffic activity to other mobile traffic navigating entities and to the one or more traffic guidance nodes;

wherein the one or more traffic guidance nodes transmit updated information about the local traffic to the one or more mobile traffic navigating entities when the one or more mobile traffic navigating entities are within a range of the one or more traffic guidance nodes;

wherein the transmitter of at least one of the one or more traffic guidance nodes is a directional transmitter.

22. The system of claim 21 wherein the directional transmitter is positioned to transmit the information about the local traffic toward a roadway having traffic affected by the information and away from a roadway having traffic not affected by the information.

23. A system comprising:

one or more traffic guidance nodes comprising;

a traffic guidance indicator;

a receiver to receive information about local traffic;

one or more sensors to detect local traffic activity and generate information about local traffic activity;

a memory to store the information about local traffic; and

a transmitter to broadcast the information about local traffic; and

one or more mobile traffic navigating entities comprising;

a receiver to receive the information from the one or more traffic guidance nodes when the traffic navigating entity is within a proximity of the one or more traffic guidance nodes;

one or more sensors to detect local traffic activity and generate information about local traffic activity;

a memory to store the information about the local traffic activity; and

a transmitter to send the information about the local traffic activity to other mobile traffic navigating entities and to the one or more traffic guidance nodes;

wherein the one or more traffic guidance nodes transmit updated information about the local traffic to the one or more mobile traffic navigating entities when the one or more mobile traffic navigating entities are within a range of the one or more traffic guidance nodes;

wherein at least one of the one or more traffic navigating entities is configured to request a change in state of the traffic guidance indicator of at least one of the one or more traffic guidance nodes.
