隧道彩色路面和侧墙设计对驾驶行为的影响分析

Analysis of effect of colored pavement and sidewall design on driving behavior in tunnels

为探究不同隧道环境设计下驾驶绩效以及驾驶员的生、心理变化特性,采用3D Max软件搭建仿真试验场景,选取15名驾驶员开展不同隧道环境设计场景下的驾驶模拟试验,采集驾驶员的生、心理及车辆运行状态数据;选取具有代表性的车辆运行指标和驾驶员状态指标,构建驾驶行为趋势面模型,分析指标之间的相对敏感程度。研究结果表明:路面铺设彩色路面可提示驾驶员适当减速,其中,黄色系渐变彩色路面和纵向减速标线彩色路面的综合效果更佳,更利于安全行车;隧道内设置装饰侧墙可缓解隧道内驾驶员视觉信息单调的现象,考虑到隧道内行车安全和通行效率,建议采用蓝-白装饰侧墙。

In order to explore the driving performance and the physical and psychological change characteristics of drivers under different tunnel environment designs,three-dimensional Max software was used to construct a simulation experiment scene.15 drivers were selected to participate in driving simulation experiments of different tunnel environment design scenarios,and the physical and psychological data of the drivers and the vehicle operation status data were collected.The representative vehicle operation indicators and driver state indicators were selected,and the driving behavior trend surface model was constructed.The relative sensitivity between the indicators was analyzed.The results show that colored pavements can prompt the driver to decelerate appropriately.The comprehensive effects of gradient yellow pavements and colored pavements with longitudinal deceleration marking are better,which are more conducive to safe driving;the decorated sidewalls in the tunnel can alleviate the phenomenon of monotonous visual information of drivers in the tunnel.In view of the driving safety and traffic efficiency in the tunnel,it is recommended to use blue-white decorated sidewalls.
