Abstract: With the development of tunnel construction in China, the problem of tunnel traffic safety has become more prominent and severe. By analyzing the braking mechanism of automobiles, it is found that shortening the reaction time of the driver plays an extremely important role in reducing the rate of traffic accidents. A system was designed to measure the reaction time of drivers under different pavement colors. Based on the simulation of the real tunnel driving environment, the relationship between different pavement color conditions and drivers reaction time was obtained through experiments. The test results show that under the most widely used black and gray pavement conditions, the driver has the longest reaction time, which is not conducive to tunnel driving safety. Based on the comprehensive analysis of the test results and the visual psychological theory of traffic color, the influence of different tunnel pavement colors on driving safety was deeply studied. Finally, it is found that the reaction time of drivers is shorter under the condition of yellow, and the color visual psychological effect of yellow is more suitable for the tunnel driving environment, which is an ideal tunnel pavement color.

摘要： 随着我国隧道建设的发展，隧道交通安全问题愈加突出和严峻。通过分析汽车的制动机理发现缩短驾驶员的反应时间对于降低交通事故率有着极其重要的作用。设计了一种测量不同路面颜色条件下驾驶员反应时间的系统，在对真实的隧道行车环境进行模拟的基础上，通过试验得到不同路面颜色条件与驾驶员反应时间的关系。试验结果表明，在目前使用最广泛的黑色、灰色路面条件下，驾驶员的反应时间最长，不利于隧道行车安全。本文结合试验结果及交通色彩视觉心理理论进行综合分析，深入研究了不同隧道路面颜色对行车安全性的影响，最终发现黄色条件下驾驶员的反应时间较短，且黄色的色彩视觉心理效应更加适用于隧道行车环境，是理想的隧道路面颜色。
