Abstract

Embodiments of this invention relate to a method of determining the risk of driving a vehicle on a road network as a function of, for example, location, time of driving, weather, road conditions, driver ability, and traffic density. Historical information for the above is statistically analyzed to come up with a predictive model. Results can be displayed or presented to a driver while driving or otherwise or another person.

Claims

1. A method, implemented using a vehicle navigation system, for determining the risk associated with driving on a plurality of elements of a transportation network by a driver comprising:

compiling, in a compilation module of the navigation system, a database of temporal and geo-referenced driving risk attribution types for the plurality of transportation elements, for a plurality of drivers and vehicles;

determining, in a risk determination module of the navigation system that is functionally connected to the compilation module, one or more driving risk indices for each of the plurality of elements that relates at least to one of the driver risk attribution types to the likelihood of damage to at least one of a person and property and optionally to the probable severity of damage of the person and property.

2. The method of claim 1 further comprising:

displaying, in a functionally connected display module of the navigation system, the driving risk indices for a plurality of transportation elements for one of;

within a mapped area or, in the vicinity of a route to be traveled or being traveled or, in the vicinity of the present location of a moving vehicle.

3. The method of claim 1 wherein the driving risk attribution types comprise at least one of the following associated with each of a plurality of accidents:

location;

time;

transportation element;

severity of damage and injury;

weather;

traffic;

speed of travel for each vehicle in each accident prior to the accident;

speed limit of the transportation segment;

road condition;

individual vehicle characteristics for each vehicle in the accident;

identification of the driver and driving record for each vehicle in the accident; and

lane closers.

4. The method of claim 2 wherein the display of the driving risk indices is a color coding relative to the amount of risk superimposed on the representation of the transportation elements.

5. The method of claim 2 wherein the indication of the driving risk indices is one or more icons placed in proximity to the associated transportation element wherein at least one of the shape and color of the one or more icons represents relative risk.

6. The method of claim 1 wherein multiple driving risk indices are calculated:

one for each driver risk attribute type and one for all driver risk attribute types statistically combined.

7. The method of claim 6 wherein a user can select which index to use and display.

8. The method of claim 2 wherein the display of driving risk flashes on and off if the risk is above a specified threshold.

9. The method of claim 1 wherein a message is one or more of displayed and annunciated if all routes away from a current or a selected location have a driving risk index greater than a specified threshold, indicating it is unsafe to drive.

10. The method of claim 2 wherein for a selected or present location of a vehicle, a safe driving speed is displayed in a corner of the map display.

11. The method of claim 1 wherein the driving risk index indicates the maximum safe driving speed for the given conditions.

12. The method of claim 1 wherein the indications of the driving risk index indicate the maximum driving risk index given any conditions or times.

13. The method of claim 2 wherein the display of driving risk indications is periodically updated with real-time information.

14. The method of claim 1 wherein only safe route are displayed wherein a safe route has all transportation elements that make up the route, below a minimum threshold driving risk rating.

15. The method of claim 1 wherein at least in part the driving risk indices are based on the mean of the driving ability of a plurality of drivers during specific driving conditions and for a specific driver, the driving risk indices are modified based on whether the driving ability of the specific driver is above or below the mean.

16. The method of claim 15 wherein the driving risk indices for the specific driver are utilized to compute an insurance cost for driving.

17. The method of claim 1 wherein a multivariate analysis is used to determine the driving risk indicies.

18. The method of claim 1 wherein individual datum of the driving risk attribution have associated metadata indicating the age of each datum and wherein the datum are deleted after the age reaches a specific threshold and the driving risk indices are recalculated.

20. The system of claim 16 wherein at least in part the driving risk indices are based on the mean of the driving ability of a plurality of drivers during specific driving conditions and for a specific driver, the driving risk indices are modified based on whether the driving ability of the specific driver is above or below the mean.

19. A vehicle navigation system, for determining the risk associated with driving on a plurality of elements of a transportation network by a driver comprising:

a compilation module configured to capture and store in a database, temporal and geo-referenced driving risk attribution types for the plurality of transportation elements, for a plurality of drivers and vehicles;

a risk determination module, functionally connected to the compilation module, configured to generate, one or more driving risk indices for each of the plurality of transportation elements that relates at least to one of the driver risk attribution types to the likelihood of damage to at least one of a person and property and optionally to the probable severity of damage of the person and property; and

a display module, functionally connected to the compilation and risk determination modules, configure to display the driving risk indices for a plurality of transportation elements for one of;

within a mapped area or, in the vicinity of a route to be traveled or being traveled or, in the vicinity of the present location of a moving vehicle.
