【摘要】：驾驶员前方视野直接影响其对危险状况的预判和处理,侧壁属于驾驶员驾车经过公路隧道时前方视野感知域的重要组成部分,因此对行车安全具有一定的影响。文章首先采用分光辐射式亮度计对不同侧壁材料的照明参数进行测定。然后结合自主研发的公路隧道照明环境模拟和效果评价装置开展试验。通过室内模拟具有相同亮度指标的公路隧道照明环境,以反应时间评价视野感知域内三种侧壁涂料对驾驶者视觉功效的影响,从而探索公路隧道照明安全节能的新途径。试验结果表明:使用蓄光反光涂料的公路隧道侧壁可显著提高照明环境亮度;在同种LED灯照明条件下,使用反射率较高且反射光光谱中黄绿光成分较多的侧壁涂料有助于提高驾驶者的视觉功效,从而有利于公路隧道的行车安全和照明节能。
[Abstract]:Driver's front visual field directly affects the prediction and handling of dangerous situation. The side wall is an important part of the perception domain of the driver's visual field when driving through a highway tunnel, so it has a certain impact on the safety of driving. In this paper, the illumination parameters of different side-wall materials are measured by spectrometer. Then combined with the road tunnel lighting environment simulation and effect evaluation device to carry out the test. Through indoor simulation of lighting environment of highway tunnel with the same luminance index, the effects of three side wall coatings in visual field perception domain on the visual efficacy of drivers were evaluated by reaction time, and a new way of safety and energy saving of road tunnel lighting was explored. The experimental results show that the side wall of highway tunnel with light storage and reflective coating can significantly improve the luminance of the lighting environment, and under the same LED lighting condition, The use of side wall coatings with higher reflectivity and more yellowish and green light in the reflectance spectrum is helpful to improve the visual efficiency of the driver and thus benefit the driving safety of highway tunnels and the energy saving of lighting.
