Influence of Tunnel Entrance Environment on Driver's Vision and Physiology in Mountainous Expressway

Abstract

In order to improve the safety and comfort of tunnel entrance, a real vehicle test was carried out in 6 tunnels on the Mountain expressway, and the visual and physiological data of the driver were collected by the Dikablis eye tracker instrument and the Varioport physiological recorder device. The index, including percentage of fixation duration, the mean of fixation time, saccade angle, the frequency of blink, skin electric were analyzed. The effects of the environment of highway tunnel entrance on the driver's vision and physiology were studied. The result shows that the tunnel entrance has a very obvious influence on the driver's vision and psychology; The color pavement of the tunnel entrance should improve the comfort of color and form; The tunnel entrance should try to encourage the use of Bamboo Cutting type tunnel form instead of putting a huge billboard.
