Research on the characteristics of driver visual behavior in highway extra-long tunnel

Abstract

In order to study the driver visual behavior in highway extra-long tunnel section, the paper used Smart Eye Pro5.7 Eye Tracking System to record the driver’s eye movement data, analyzed eye movement index, such as pupil area, X sight angle, Y sight angle, percentage of fixation times, percentage of fixation time and mean fixation time. The results showed that the driver’s pupil area changes rapidly to adapt brightness variation in the entrance and exit of the tunnel. After entering the tunnel, the psychological state of drivers tends to be stable, and there is a tendency of gradual relaxation. Drivers are more focused and look down.
