摘要: 为了实现安全、低碳、节能的隧道照明条件,分析了驾驶人对隧道入口段照明的驾驶视觉需求特性及照明条件对驾驶人安全舒适性驾驶瞳孔面积变化率的影响;通过对山区高速公路24名典型车型驾驶人进行实车试验数据采集和分析,采用瞳孔面积变化率作为评价隧道入口段照明条件安全舒适性的指标,建立了驾驶人在隧道入口段瞳孔面积变化率、亮度折减系数及运行速度的逻辑回归模型;以瞳孔面积变化率20%作为表征驾驶人驾驶紧张程度和驾驶安全舒适性的阈值,并将其代入逻辑回归模型进行计算。结果表明:限速60 km·h-1的隧道入口段驾驶安全舒适性照明亮度折减系数为0.028,比现行规范值要求高;研究方法和结论对高速公路隧道入口段照明设计和运行管理等理论、方法和实践具有参考价值。

Abstract: In order to achieve energy saving and low carbon tunnel lighting conditions with safety considered, the driver visual request characteristics and the influence of tunnel entrance section lighting on changing rate of driver's pupil were analyzed. By experiment designing, typical vehicles were chosen for real vehicle testing with a random sample of 24 drivers on tunnel entrance section of the mountainous expressway and tested data were collected and analyzed. The changing rate of pupil was selected as the evaluation index to evaluate the driving safety and comfort of tunnel entrance section lighting. The logistic regression model of changing rate of driver's pupil, luminance reduction coefficient and vehicle operation speed was established. The changing rate of pupil which could be used to describe driving tension degree and changing rate of pupil (20%) for safety and comfort threshold the safety and comfort threshold were put in the logistic regression model for verification. The results show that the safety and comfort luminance reduction coefficient of tunnel entrance section with a speed limit of 60 km·h-1 is 0.028 which is higher than current standard specification. The research method and conclusions can provide theory, method and practice value for the expressway tunnel lighting design and operation management at the tunnel entrance section.

Key words: traffic engineering, tunnel threshold zone lighting, driving safety and comfort evaluation method, luminance reduction coefficient, changing rate of pupil
