Abstract

A system for using a traffic proxy measure includes an input interface and a processor. The input interface is to receive a vehicle data and a road data. A processor is to determine a traffic proxy measure based at least in part on the vehicle data and the road data.

Claims

1. A system for determining an event recorder threshold using a traffic proxy measure, comprising:

an input interface to;

receive a vehicle data and a road data; and

a processor to;

determine a traffic proxy measure based at least in part on the vehicle data and the road data;

determine whether to update the event recorder threshold based at least in part on the traffic proxy measure; and

in the event that it is determined to update the event recorder threshold, update the event recorder threshold.

2. The system of claim 1, wherein the vehicle data comprises a vehicle speed, wherein the vehicle speed is received from a GPS.

3. The system of claim 1, wherein the vehicle data comprises a vehicle speed, wherein the vehicle speed is received from a vehicle sensor.

4. The system of claim 1, wherein the vehicle data comprises a speed of one or more nearby vehicles.

5. The system of claim 1, wherein the vehicle data comprises a distance to one or more nearby vehicles.

6. The system of claim 1, wherein the road data comprises a posted speed, wherein the posted speed is determined using a posted speed database.

7. The system of claim 1, wherein the road data comprises a posted speed, wherein the posted speed is determined using map data.

8. The system of claim 1, wherein the road data comprises a posted speed, wherein the posted speed is determined using GPS data.

9. The system of claim 1, wherein the road data comprises a posted speed, wherein the posted speed is determined using a captured image of a speed limit sign.

10. The system of claim 9, wherein the captured image of the speed limit sign is captured using an event recorder.

11. The system of claim 1, wherein the road data comprises a road type, wherein the road type is determined using a road type database.

12. The system of claim 1, wherein the road data comprises a road type, wherein the road type is determined using map data.

13. The system of claim 1, wherein the road data comprises a road type, wherein the road type is determined using GPS data.

14. The system of claim 1, wherein the traffic proxy measure is based at least in part on a ratio of a vehicle speed and a posted speed.

15. The system of claim 1, wherein determining whether to update the event recorder threshold is based at least in part on the traffic proxy measure being less than a traffic proxy measure threshold.

16. The system of claim 15, wherein the traffic proxy measure threshold is one of the following:

0.9, 0.5, 0.3, 0.2, or 0.1.

17. The system of claim 1, wherein determining whether to update the event recorder threshold is based at least in part on the traffic proxy measure being below a traffic proxy measure threshold for more than a threshold fraction of time.

18. The system of claim 1, wherein determining whether to update the event recorder threshold is based at least in part on the traffic proxy measure passing below a traffic proxy measure threshold more than a threshold number of times.

19. The system of claim 1, wherein the event recorder threshold comprises an event trigger threshold.

20. The system of claim 1, wherein the processor is further to determine whether to record event data.

21. The system of claim 1, wherein the processor is further to determine whether to transmit event data.

22. A method for determining an event recorder threshold using a traffic proxy measure, comprising:

receiving a vehicle data and a road data;

determining, using a processor, a traffic proxy measure based at least in part on the vehicle data and road data;

determining whether to update the event recorder threshold based at least in part on the traffic proxy measure; and

in the event that it is determined to update the event recorder threshold, updating the event recorder threshold.

23. A computer program product for determining an event recorder threshold using a traffic proxy measure, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving a vehicle data and a road data;

determining a traffic proxy measure based at least in part on the vehicle data and road data;

determining whether to update the event recorder threshold based at least in part on the traffic proxy measure; and

in the event that it is determined to update the event recorder threshold, updating the event recorder threshold.
