The Design of Wall Pictures to Relieve Driving Fatigue in the Long Tunnel

Abstract

The purpose of this study was to use specially-designed of wall pictures in tunnels to reduce drivers’ negative emotions and enhance positive ones. The three experiments were: investigation of the current driving experience in Hsuehshan Tunnel, the selection of wall pictures, and simulated driving with the designated pictures. The results showed that drivers had more positive emotions and less negative responses in the tunnel with pictures than in the one without pictures. When the pictures changed between each stage, more positive emotions occurred. Pictures with brightness and color changes showed better effects. The length and brightness of the pictures affected drivers’ visual and spatial feelings. Drivers had different speed feelings in stages with different pictures. The rules of pictures’ changes should be able to be recognized by drivers. Pictures lacking a good order will cause negative responses. Brightness changes resemble the change of lightness in the environment. Proper use the design of wall pictures helps ease drivers’ negative emotions and enhance positive ones.
