Abstract

A system includes a processor configured to gather historical risk-affecting data with respect to a current road. The processor is also configured to gather current risk-affecting data with respect to the current road. Further, the processor is configured to generate a baseline risk index for the road based on the historical data. The processor is additionally configured to modify the baseline risk index based on the current data and provide a risk index value for the current road based on the modified baseline risk index

First claim

What is claimed is:

1. A system comprising:
a processor configured to:
gather historical accident-risk-affecting data and current accident-risk-affecting conditions with respect to a current road;
weight an effect that the conditions have on a known driver, based on a driver profile storing observed effects on driving behavior under similar conditions;
generate a risk value, representing an accident likelihood, for the driver, based on the historical data and the weighted effect; and
present the risk value to the driver.

2. The system of claim 1 , wherein the historical accident-risk-affecting data includes road data.

3. The system of claim 1 , wherein the current accident-risk-affecting conditions includes current road conditions.

4. The system of claim 1 , wherein the historical accident-risk-affecting data includes traffic data.

5. The system of claim 1 , wherein the current accident-risk-affecting conditions includes current traffic conditions.

6. The system of claim 1 , wherein the historical accident-risk-affecting data includes environmental data.

7. The system of claim 1 , wherein the current accident-risk-affecting conditions includes current environmental conditions.

8. The system of claim 1 , wherein the current accident-risk-affecting conditions includes a current vehicle operator state.

9. The system of claim 1 , wherein the historical accident-risk-affecting data includes vehicle system state data.

10. The system of claim 1 , wherein the current accident-risk-affecting conditions includes current vehicle system conditions.

11. The system of claim 1 , wherein the processor is further configured to generate the risk value based on observed effects of the historical risk-affecting data with respect to the current road.

12. The system of claim 1 , wherein the processor is further configured to generate the risk value based on observed effects of the historical risk-affecting data with respect to roads having similar characteristics to the current road.

13. A computer-implemented method comprising:
gathering historical accident-risk-affecting data and current accident-risk-affecting conditions with respect to a current road;
weighting an effect that the conditions have on a known driver, based on a driver profile storing observed effects on driving behavior under similar conditions;
generating a risk value, representing an accident likelihood, for the driver, based on the historical data and the weighted effect; and
presenting the risk value to the driver.

14. A non-transitory machine-readable storage medium, storing instructions that, when executed, cause a processor to perform a method comprising:
gathering historical accident-risk-affecting data and current accident-risk-affecting conditions with respect to a current road;
weighting an effect that the conditions have on a known driver, based on a driver profile storing observed effects on driving behavior under similar conditions;
generating a risk value, representing an accident likelihood, for the driver, based on the historical data and the weighted effect; and
presenting the risk value to the driver.
