Abstract The provision of a fatigue mitigation light belt in highway tunnels can improve drivers′ visual environ?
ment. However, if its design is too complicated, drivers will shift their attention to the light belts, which will endanger the driving safety. Hence, based on the Yanglin extra-long tunnel, the eye movement characteristics of the driver in the fatigue mitigation light belt section and the other tunnel sections are tested using the eye tracker, and the law of influence of the fatigue mitigation light belt on the eye movement characteristics is obtained by comparison. The results show that the drivers′fixation range in the light belt section is expanded and distributed linearly to the tunnel walls on both sides; the drivers′fixation time on the tunnel wall in the light belt section is longer, but it is still much shorter than the fixation time on the far distance in the central main visual area; in the tunnel section with the fa?
tigue mitigation light belt, the drivers′eye movement type in the central main visual area is almost gaze, with the eye saccade occupying a certain proportion in the areas of tunnel walls on both sides; when passing through the fatigue mitigation light belt section of Yanglin extra-long tunnel, the drivers′ main concern is still the road ahead and the driver can easily obtain and perceive the information of the wall pattern.
