Abstract Vehicle lighting test was carried out and three-dimensional simulation was used to study and analyze the lighting effect in the tunnel under the three different conditions of vehicle lights, tunnel luminaries, as well as the combination of vehicle lights and luminaries. The results show that the luminance decreases significantly in the distance from vehicle lights, the longitudinal effective illumination range of vehicle lights is 20 m and the transverse effective illumination range is 3.75 m. When the vehicle is located in the right lane, the maximum luminance at centerline of right lane under luminaries used in this paper is 1.6 cd·m-2,while the maximum luminance under vehicle lights is 5.6 cd·m-2. The luminance at centerline of right lane under the combined effect of vehicle lights and luminaries reaches to the maximum value of 7.1 cd·m-2. The maximum luminance at centerline of right lane under the combined effect of vehicle lights and luminaries increase by more than 300% compared to luminaries lighting, and 27% compared to vehicle lighting.
