In the lighting environments of different color temperatures, people's visual perceptions are different, and the response time for identifying obstacles will also change accordingly, affecting driving safety. Self-designed dual darkroom experimental system, the lighting luminance of the special long tunnel based on the Zhongnanshan Highway is set to 1.6 cd/m2. Eight kinds of color temperatures (2500 K, 3500 K, 4500 K, 5500 K, 6500 K, 7500 K, 8500 K, and 9500 K) were selected to measure the time in which the visual acuity tester judged the direction of the Landolt ring opening. The results show that the color temperature is 2500K, the average reaction time is the largest, reaching 1253.0ms; the color temperature is 7500K, and the average reaction time is the smallest, reaching 941.4ms. Suggested the color temperature setting of the Zhongnanshan Highway Tunnel.
