Abstract

Embodiments of the present invention provide a system and method for automatic driver evaluation of a person'"'"'s driving capabilities and render an outcome of pass or fail without the need for a trained observer to evaluate driver'"'"'s performance. In one embodiment, the automatic driver evaluation system facilitates the display of a predetermined driving route designed for a predetermined demography, observe simulated driving performance of a user on the predetermined driving route, record errors made by the user while performing the simulated drive, and compare the performance errors to at least one threshold value and generate a score based on the comparison.

7. The method according to claim 1, wherein the types of performance errors include traffic violations, wherein traffic violations include one or more of running red light, running stop sign, speeding, driving at a speed of at least 10 miles per hour less than the posted speed limit, stopping without reason, and straddling lane for at least 6 seconds.

8. The method according to claim 1, wherein the types of performance errors include rule violations, wherein rule violations include one or more of failing to turn, turning in direction opposite of command, and poor control of vehicle during divided attention task.

9. The method according to claim 1, wherein the errors made by the user while performing the simulated drive is determined for at least 30 minutes.

10. The method according to claim 1, wherein the errors made by the user while performing the simulated drive is determined until the completion of the last driving task in the selected driving route.

11. The method according to claim 1, wherein the selected driving route includes at least one urban course.

12. The method according to claim 1, wherein the demography is based on age.

13. The method of claim 12, wherein the demography is for one of drivers over a certain age, and drivers under a certain age.

14. The method according to claim 1, wherein the demography is based on one or more medical conditions.

15. The method according to claim 1, wherein the demography is based on particular types of driving a driver is expected to perform.

16. The method of claim 1, wherein the predetermined time period is sufficient to test the user'"'"'s ability to drive a typical length of drive without losing concentration for the demography associated with the user.

17. The method of claim 1, wherein the at least one threshold value includes at least one hazardous error, at least two traffic violations, or at least one rule violation and at least one traffic violation.

18. The method of claim 1, wherein the types of performance errors include hazardous errors, traffic violations, and rule violations.

19. A system for automatically evaluating driving capabilities of a user in a simulated environment comprising:
