Abstract:

To improve the safety performance of urban tunnels, the fixation transfer characteristics of drivers with different driving experience levels in urban tunnels were investigated. First, a real vehicle test was performed in an urban tunnel, and the eye movement data of 10 drivers with different driving experience levels were collected using a Dikablis eye-tracking system. Second, the driver fixation range was divided into eight areas of visual interest by using the K-means clustering method, and the fixations in different sections of the tunnel were comparatively analyzed. Finally, on the basis of the divided areas of visual interest, fixation transfer rules and the stationary distribution characteristics of drivers with different driving experience levels on different sections of the tunnel were discussed using Markov theory. Results indicate that drivers’ probability of repeated fixation is greater and that the efficiency of visual search is lower at internal sections of tunnels than in external sections. Drivers obtain information mainly from the straight upper front and straight lower front areas, and the probabilities of fixation points in these two areas at the threshold and exit sections are significantly higher than those in other sections. Relative to experienced drivers, novice drivers allocate little attention to the straight upper front area and rear-view mirrors. Hence, they have weak fixation when looking forward, and they lack experience in obtaining information on rear-approaching vehicles and controlling speed.
