Abstract

Methods and apparatus are provided for displaying traffic status information to a user of a vehicle. An onboard vehicle methodology as described herein receives traffic image data corresponding to a picture of a road section, and displays the picture of the road section on an onboard display element of the vehicle.

Claims

1. A method of displaying traffic status information to a user of a vehicle, the method comprising:

receiving traffic image data corresponding to a picture of a road section; and

displaying the picture of the road section on an onboard display element of the vehicle.

2. The method of claim 1, further comprising:

obtaining location data corresponding to a current location of the vehicle;

determining a distance between the current location and the road section; and

comparing the distance to a threshold distance, wherein displaying the picture of the road section is triggered when the distance is less than the threshold distance.

3. The method of claim 1, further comprising transmitting a request for updated traffic image data from the vehicle to a remote command center, wherein receiving traffic image data is performed in response to the transmitting step.

4. The method of claim 1, further comprising removing the picture of the road section from the onboard display element after a designated time period.

5. The method of claim 1, further comprising displaying a map image on the onboard display element of the vehicle, wherein displaying the picture of the road section comprises superimposing the picture of the road section over the map image.

6. The method of claim 1, further comprising displaying a map image on the onboard display element of the vehicle, the map image comprising a graphical icon that identifies the road section.

7. The method of claim 1, further comprising displaying a map image on the onboard display element of the vehicle, the map image comprising a graphical icon that identifies a location of a source of the traffic image data.

8. A method of displaying traffic status information to a user of a vehicle, the method comprising:

storing a plurality of road section images corresponding to a respective plurality of different road sections;

selecting one of the plurality of road section images, resulting in a selected road section image; and

displaying the selected road section image on an onboard display element of the vehicle.

9. The method of claim 8, further comprising:

obtaining a current location of the vehicle;

determining, based upon the current location of the vehicle, a closest one of the plurality of different road sections; and

choosing, from the plurality of road section images, a next road section image that corresponds to the closest one of the plurality of different road sections, wherein selecting one of the plurality of road section images comprises selecting the next road section image.

10. The method of claim 8, further comprising receiving the plurality of road section images from a remote command center.

11. The method of claim 8, wherein the plurality of different road sections are sections of a road on which the vehicle is traveling.

12. The method of claim 8, further comprising:

receiving a plurality of updated road section images corresponding to the plurality of different road sections; and

storing the plurality of updated road section images.

13. The method of claim 8, further comprising displaying a map image on the onboard display element of the vehicle, wherein displaying the selected road section image comprises superimposing the selected road section image over the map image.

14. The method of claim 8, further comprising:

capturing the plurality of road section images from cameras located at the plurality of different road sections;

transmitting the plurality of road section images to a remote command center; and

sending the plurality of road section images to an onboard system of the vehicle.

15. A traffic status system for a vehicle, the system comprising:

a data communication module configured to receive traffic image data indicative of a picture of a road section;

a display driver coupled to the data communication module, the display driver being configured to process the traffic image data for display; and

a display element coupled to the display driver, the display element being configured to display the picture of the road section.

16. The system of claim 15, the data communication module being configured to transmit a request for updated traffic image data from the vehicle to a remote command center.

17. The system of claim 15, the display driver being configured to render a map image on the display element.

18. The system of claim 15, further comprising:

a traffic camera configured to capture the traffic image data; and

a remote command center configured to receive the traffic image data from the traffic camera, and configured to transmit the traffic image data to the data communication module.

19. The system of claim 15, the display driver being configured to remove the picture of the road section from the display element after a designated time period.

20. The system of claim 15, further comprising:

means for obtaining location data corresponding to a current location of the vehicle;

means for determining a distance between the current location and the road section; and

means for comparing the distance to a threshold distance, wherein the display driver initiates display of the picture of the road section when the distance is less than the threshold distance.
