Abstract Reaction time is an important index for the evaluation of safety regarding tunnel lighting. The existing tunnel lighting design method can be optimized by measuring reaction time for different lighting conditions. Focusing on reaction time research, a scale model was developed for an innovative integrated system of tunnel lighting that can simulate real driving visuals and the luminous environment inside a tunnel based on eye tracking technology. The system was used to test reaction times for different luminosities, uniformities and lamp elevation angles, and the results show that: 1) the influences of tunnel road luminance on reaction time are consist with the Weber-Fechner law, and the testers have shorter reaction times when the contrast is 0.6; 2) compared with the recognition time, the detection time is more sensitive to road luminance uniformity, so the higher the road luminance uniformity the more unfavorable the reaction time; 3) a high lamp elevation angle induces glare and prolongs the reaction time. The innovative development of this integrated tunnel lighting scale model system provides effective experimental conditions for the research of the influences of tunnel lighting parameters on a driver′s reaction time, and is therefore valuable and applicable to domestic tunnel lighting projects.
