Research on the Influence of Diffuse Reflectance of Light-Storing Reflective Material on the Quality of Tunnel Lighting

Based on visual performance, the study aims at the driving safety of highway tunnel, by using indoor model experiment to analyze the small target visibility and reaction time, the influence of the diffuse reflectance of energy-storing and reflective materials on the quality of tunnel lighting is studied. The results show: (1) the value of illuminance, luminance and longitudinal uniformity ratio of illuminance increases with the increase of the diffuse reflectance of side wall with energy-storing and reflective materials coated on; (2) small target visibility increases with the increase of the diffuse reflectance of side wall with energy-storing and reflective materials coated on; (3) small target recognition reaction time decreases with the increase of the diffuse reflectance of side wall with energy-storing and reflective materials coated on; (4) energy-storing and` reflective materials can improve the visual performance of the driver, which benefits the safety of tunnel as well as the quality of tunnel lighting.
