Abstract

A device and method for filtering traffic information. 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 traffic data corresponding to a plurality of traffic events. The computing device is operable to filter the received traffic data based on the severity of the traffic events to form filtered traffic data and the display is operable to present an indication of the filtered data.

Claims

1. A device, comprising:

a traffic component operable to receive traffic data corresponding to a plurality of traffic events;

a computing device coupled with the traffic component, the computing device operable to acquire a current geographic location of the device and calculate an estimated delay time utilizing the received traffic data; and

a display coupled with the computing device, the display operable to be controlled by the computing device to present a map of an area in proximity to the current geographic location of the device and overlay on the map an indication of the estimated delay time.

2. The device of claim 1, wherein the computing device is further operable to determine a severity for each of the traffic events and exclude low severity events from the calculation of the estimated delay time.

3. The device of claim 1, wherein the computing device is further operable to

acquire a current geographic location of the device,

identify a road currently traveled by the device utilizing the acquired current geographic location, and

exclude traffic events not corresponding to the currently traveled road from the estimated delay time calculation.

4. The device of claim 1, wherein the computing device is further operable to

acquire a current geographic location of the device,

calculate a route from the current geographic location to a destination, and

exclude traffic events not corresponding to the route from the estimated delay time calculation.

5. The device of claim 1, further including a speaker coupled with the computing device, the speaker operable to audibly indicate the estimated delay time.

6. A device, comprising:

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

a communications element operable to wirelessly receive traffic data corresponding to a plurality of traffic events;

a memory including a map information database;

a computing device coupled with the location determining component, the communications element, and the memory, the computing device operable to identify traffic events corresponding to the current geographic location of the device and calculate an estimated delay time based on the identified traffic events; and

a display coupled with the computing device, the display operable to be controlled by the computing device to present;

a map of an area in proximity to the current geographic location of the device,

one or more traffic icons placed on the map corresponding to the location of one or more of the identified traffic events, and

an overlay on the map including an indication of the estimated delay time.

7. The device of claim 6, further including a portable and handheld housing for housing the location determining component, the communications element, the memory, the computing device, and the display.

8. The device of claim 6, wherein the communication element is selected from the group consisting of a cellular telecommunications transceiver, a FM-RDS radio traffic receiver, and a Wi-Fi communications transceiver.

9. The device of claim 6, wherein the received traffic data includes Traffic Message Channel (TMC) formatted information.

10. The device of claim 6, wherein the computing device is further operable to determine a severity for each of the traffic events and exclude low severity events from the calculation of the estimated delay time.

11. The device of claim 6, wherein the display presents the overlay on the map only when the estimated delay time exceeds a minimum threshold.

12. The device of claim 6, wherein the overlay comprises a magnified icon having a size larger than any one of the traffic icons.

13. The device of claim 6, wherein the computing device is operable to calculate a route from the current geographic location to a destination and the identified traffic events correspond to traffic events associated with the calculated route.

14. The device of claim 6, wherein the computing device is operable to identify a road currently traveled by the device based on the current geographic location of the device and the identified traffic events correspond to traffic events associated with the identified road.
