Abstract

In order to understand the perception-decision-operation pattern of driver, the eye movements and fixation distributions of driver, and relevant vehicle speeds were measured by eye-measured instrument while driver drove between two barriers with five different space widths, which are 7.0, 4.4, 3.5, 3.0 and 2.0 m. Analysis result of driver fixation distributions concerning different widths shows that driver concentrates his vision on the central area of road and farther to vehicle when there were no barriers on road (referring to 7. 0 m space width) , he concentrates his vision on the central area of road and left barrier when the space is enough to pass (referring to 4. 4 and 3. 5 m space widths) , he quickly scans between barriers when the width becomes narrow (referring to 3 m space width), he fixates closer to vehicle and his fixation duration decreases when the driving task becomes more difficult to fulfill.
