Abstract

A device, system, and method for grouping traffic events. In one embodiment, the device comprises a traffic component, a computing device coupled with the traffic component, and a display coupled with the computing device. The traffic component is operable to receive data corresponding to a plurality of traffic events. The computing device is operable to identify at least two related traffic events and form a traffic event group representing at least two of the related traffic events. The display is operable to present an indication of the formed traffic event group. Such a configuration enables users to more easily access relevant traffic information.

Claims

1. A navigation device, comprising:

a location determining component to determine the current geographic location of the device;

a traffic component to receive data corresponding to a plurality of traffic events from one or more traffic information sources;

a computing device coupled with the traffic component and the location determining component, the computing device to acquire a current geographic location of the device from the location determining component, identify at least two related traffic events, and form a traffic event group representing at least two of the related traffic events; and

a display coupled with the computing device, the display to present an indication of the traffic event group.

2. The device of claim 1, wherein the received data corresponding to the traffic events includes location information for each of the traffic events and the computing device compares the current geographic location of the device to the traffic event locations and forms the traffic event group if it includes at least one event location within a predetermined range from the current geographic location of the device.

3. The device of claim 1, wherein the indication of the traffic event group is displayed in relation to the current geographic location of the device.

4. The device of claim 1, wherein the computing device calculates a route from the current geographic location to a destination and forms the traffic event group if it includes at least one event located on the calculated route.

5. The device of claim 1, wherein the received data corresponding to the traffic events includes location information for each of the traffic events and the computing device identifies related traffic events according to the location information.

6. The device of claim 1, wherein the received data corresponding to the traffic events includes flow information for at least one of the traffic events and the computing device identifies related traffic events according to the flow information.

7. The device of claim 1, wherein the computing device determines a severity of each traffic event based upon the received data and identifies related traffic events according to their severity.

8. The device of claim 1, wherein the traffic component receives at least one of traffic message channel (TMC) formatted information, XM Radio formatted traffic information, and MSN Direct formatted traffic information.

9. The device of claim 1, wherein the computing device and traffic component are integral.

10. The device of claim 1, wherein the display is mounted separately from the traffic component and the computing device.

11. A method of grouping traffic events on a portable navigation device, the method comprising:

acquiring a current geographic location of a user using a location determining component associated with the portable navigation device;

accessing data corresponding to a plurality of traffic events using a traffic component associated with the portable navigation device;

identifying at least two related traffic events;

forming a traffic event group representing at least two of the related traffic events; and

presenting an indication of the traffic event group on a display of the portable navigation device.

12. The method of claim 11, wherein the data corresponding to the plurality of traffic events is accessed by wirelessly receiving the data.

13. The method of claim 11, wherein the data corresponding to the plurality of traffic events is accessed by retrieving previously stored data from a memory.

14. The method of claim 11, wherein the accessed data corresponding to the traffic events includes location information for each of the traffic events and the related traffic events are identified according to the location information.

15. The method of claim 11, wherein the accessed data corresponding to the traffic events includes flow information for at least one of the traffic events and the related traffic events are identified according to the flow information.

16. The method of claim 11, further including identifying a severity of each traffic event based upon the received data and identifying related traffic events according to their severity.

17. The method of claim 11, wherein the accessed data includes at least one of traffic message channel (TMC) formatted information, XM Radio formatted traffic information, and MSN Direct formatted traffic information.

18. The method of claim 11, wherein the indication of the formed traffic event group is additionally presented audibly to the user.
