Active Attention

This study evaluates a method for detecting driver fatigue impairment by analyzing the driver's micro control during a driving simulator experiment. The experiment involved 10 shift workers (5 male, 5 female) driving for 2 hours on a rural road, under two conditions: after a night's work and after a normal sleep. The study compares the results of the analysis to subjective ratings of driver fatigue.

  1. Active Attention A driving simulator experiment

  2. Evaluation of an method to detect driver fatigue impairment based on analysis of the driver’s micro control Objective

  3. 10 shift workers (5 male, 5 female) 2 hours drive, two occasions (morning) after a night’s work after a normal sleep Rural road, oncoming cars Double blind test Data in 5 minute blocks, random order, missing data replaced – equal number of sections for all subjects Method

  4. Mean age 37 years Mean license age 16.4 years Mean annual driving distance 9500 km 4 had near accident experiences Most shift workers for 5 - 9 years Subjects

  5. Driving behaviour Physiology speed - EOG (duration, freq.) lateral position TLC KSS ratings steering wheel angle - driver (5 min) lateral acceleration - test leader (5 min) steering wheel torque Questionnaires - pre and post Measures

  6. Road – vehicle geometry

  7. Analysis approach • Comparing AA results to KSS driver ratings • correlation • multiple regression • Reference • Driver’s lateral and longitudinal control • Blink duration (< 0.5 s) and frequency • Test leader KSS ratings

  8. KSS Driver Ratings

  9. KSS Driver and Test Leader

  10. 4 drivers were not able to complete fatigued driving condition 11 “accidents” 4 wheels off the road 10 “fatigued”, 1 “alert” 10 at KSS level 9, 1 at KSS level 8 Results - driving behaviour

  11. Correlations – all driversKSS – Driving behaviour

  12. Correlations per driverKSS – Driving behaviour

  13. Regression Analysis Driver 1

  14. Correlations – all drivers KSS to AA0 -5

  15. Correlations per driver KSS to AA0 -5

  16. Driver 1

  17. Driver 3 Stopped driving

  18. Driver 8

  19. Driver 1 block 3

  20. Driver 1 – block 36

  21. Steering angle Driver 1

  22. Road departures4 wheels off the road

  23. Subject 3 – block 34

  24. Subject 3 – block 35
