Abstract

In order to ensure traffic safety in long urban tunnels and to improve traffic efficiency, visual environment characteristics of these tunnels with multiple off-ramps were analyzed, and a stereoscopic guiding visual reference system was constructed based on visual illusion mechanism and color psychology principles. Then, an experiment of drivers' psychophysics perception was carried out by using E-prime software to study the system's effect on improving traffic safety in long urban tunnels and its optimized design. The results show that drivers are most comfortable with blue and green information while yellow has a strong warning effect but causes no sharp stimulus, which enhances driving attention. The reference system effectively shortens drivers' visual recognition time of guiding information and increases recognition distance. In addition, rhythm designs are moderately inclined to the entrance and the exit in order to induce drivers to have reasonable slope illusion. When it is 75° inclined, drivers can achieve best speed control on tunnel slopes. © 2020 China Safety Science Journal. All rights reserved.
