| 摘 要： | 从驾驶视认需求角度出发，研究在自由流条件下隧道中间段亮度与驾驶员安全视认需求的关系。以色温5700 K、显色指数70的LED灯为隧道基本照明灯具，通过驾驶员在光源特性下的动态视认试验，分析驾驶员在隧道中间段的视觉特性及需求，得出自由流、不同设计速度条件下能满足驾驶员安全视认需求的亮度阈值，研究结论均低于现行规范标准。

| Abstract: | In view of the driving visual cognition demands, the relationship between the luminance of tunnel interior zone and the demand of the drivers’ safe visual cognition in the case of free flow was studied . With the LED lamps at color temperature of 5 700 K and color rendering index of 70 as the basic lighting lamps for tunnels, by analyzing of the drivers’ visual features and the demands in the interior zone of the tunnel, the threshold value of luminance for the drivers’ safe visual cognition demands at different design speeds in the case of free flow was concluded through the dynamic visual cognition test under the characteristics of light source. The research result shows that the driving visual cognition demand is lower than that of the current standard. |
