Visual Search Pattern of Novice and Veteran Drivers on Rural Road Dangerous Sections

摘要

30 subjects were selected in the experiment and visual feature parameters were collected by eye tracker. Based on screening of effective data, the pupil diameter, fixation, and saccade were compared. The significance of statistics has been analyzed in statistics and data mining methods to find the differences of visual features between novice and veteran drivers on rural road. The result shows novice drivers' pupil diameter changes dramatically on rural road, while the veteran drivers' pupil diameter changes very slowly. The novice drivers show the fixation features of a long period, while the veteran drivers show the characteristics of short time fixation. The average fixation time of the veteran driver on the left turn curve is longer than that of the right turn curve. The saccade speed and amplitude of the veteran drivers are larger than the novice drivers.
