摘要
基于视觉功效法,针对公路隧道中的安全问题,开展小目标可见度和反应时间室内模型试验,研究蓄能反光材料漫反射率对隧道照明质量的影响,研究表明:(1)路面照度、亮度和纵向均匀度随着蓄能反光材料漫反射率的增大而增大;(2)小目标可见度随着涂刷有蓄能反光材料侧壁板的漫反射率的增大而增大;(3)小目标识别反应时间随着蓄能反光材料侧壁板漫反射率的增大而减小;(4)漫反射率大的蓄能反光材料在隧道中应用能够提高驾驶员的视觉功效,提高隧道照明安全性,提升隧道环境照明质量。
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.
