  • Figure 1. Driver’s state during unfocused driving
  • Figure 2. Experimental course. Ashikaga city was defined as an urban area and the region between Ashikaga city and Sano city was defined as a suburban area. The subjects drove along a 35 km long route and then returned via a 29 km long route. In addition, they took a little rest in Sano city
  • Figure 3. Experimental system. Eye movement is measured by the eye-mark recorder and EOG, and vehicle behavior, such as steering angle, velocity, and turning signal, are measured by CAN and recorded by a data-logging system
  • Figure 4. Picture of the experimental situation. The upper-left picture shows the field view from the eye-mark recorder, lower-left picture is the front scene from a stereo camera, and lower right is the face of a subject
  • Figure 5. Cut-out point (from t=t1 to t=t2)
  • Figure 6. Comparing Start and Finish based on the standard deviation of the visible degree. The standard deviation at Finish seems larger than that at Start for both Subjects A and B
  • Figure 7. Comparison of the standard deviations of visual angle under three driving conditions: Except urban area or suburb, urban area, and suburban area. The standard deviation of visible degree and eye-gaze-occurrence frequency are observed to be larger in the urban area than in the suburban area
  • Figure 8. Comparison of rate of eye gaze under three different driving conditions: Except urban area or suburb, urban area, and suburban area. The eye-gaze rate and occurrence frequency were larger in the urban area than in the suburban area
  • Figure 9. Change in eye movement from transiting “without leading vehicle” and from transiting “with leading vehicle” (slow eye movement)
  • Figure 10. Change in eye movement for transiting “without leading vehicle” and for transiting “with leading vehicle” (fast eye movement)
  • Figure 11. Change in eye movement for transiting “with leading vehicle” and for transiting “without leading vehicle” (slow eye movement)
  • Figure 12. Change in eye movement for transiting “with leading vehicle” and for transiting “without leading vehicle” (fast eye movement)
