Abstract When drivers enter a tunnel, the sudden change in luminance environment can cause visual dark adapta? tion, leading to the so-called "black hole effect," which severely reduces drivers' visual recognition ability and easily causes traffic accidents. In view of this, this paper proposes laying brightly colored pavement at the tunnel entrance to increase the brightness in the tunnel, thereby mitigating the adverse effects of the "black hole effect." Real vehicle tests were conducted to quantitatively evaluate drivers' visual recognition ability under colored pavement conditions. The results show that the obstacle detection distances for drivers under original, green, red, and yellow pavement conditions distance are obtained through distance measurement tests, revealing that all three colored pavements improved drivers' visual recognition ability to varying degrees, with the yellow pavement showing the greatest improvement.
