摘要： 为了合理确定城市道路人行横道处的照明指标,保证驾驶人对过街行人的有效视认,进行了驾驶人夜间视认距离试验研究。分析了过街行人数量、状态(静止或运动)及衣服颜色对驾驶人夜间识别距离的影响,以及不同车速条件下驾驶人夜间视认距离随平均照度的变化规律,构建了驾驶人夜间视认距离-平均照度-车速关系模型。基于驾驶人夜间视认距离与反应制动距离间的安全行驶判别条件,提出了城市道路人行横道处平均照度的计算方法,并给出了实际案例。研究结果表明:当单个过街行人静止且衣服颜色较深时,驾驶人夜间对其进行视认最为困难;驾驶人夜间视认距离与平均照度呈正对数相关,与行驶速度呈负线性相关。

Abstract: In order to determine reasonable lighting parameter of crosswalk of urban road and ensure driver's recognition of crossing pedestrian, experimental research on driver distance recognition at night was conducted. The impacts of the number, the state (static or moving) and the cloth color of crossing pedestrians on the driver recognizing distance were analyzed. The relationship between driver recognizing distance and average luminance at different driving speed was also studied. Then a model was established to relate the driver recognizing distance, the average luminance and the driving speed. A calculation method of the average luminance value of crosswalk of urban road at night was presented based on safe discriminating conditions between driver recognizing distance and response-braking distance. A case study using this method was carried out. Results show that it is more difficult for drivers to recognize crossing pedestrian at night when single pedestrian is static and the cloth color is dark. There exist a positive logarithm relation between driver recognizing distance and average luminance, and a negative linear relation between driver recognizing distance and driving speed.

Key words: engineering of communications and transportations, driver, crossing pedestrian, recognition distance, average luminance
