摘  要:山区高速公路隧道出口至互通净距短,易导致驾驶员分流操作时间短,安全风险较高。研究在四处隧道出口毗邻互通出口路段开展了实车试验,获取了驾驶员在正常驾驶条件下的分流时间,并进一步分析了分布特征以及该特殊路段对驾驶行为的影响。结果表明,随着隧道出口至互通的净距减小,车辆分流时间减少,分流过程更加急促。分流起点处,位于左侧车道的车辆分流时间明显少于右侧车道,行车风险更大。The short clear distance from the exit of the expressway tunnel in the mountainous area to the interchange can easily lead to the short diversion operation time for drivers and higher safety risks.The real vehicle tests on the sections of tunnel exits adjacent to interchange exits are carried out through the research,the diversion time for drivers under normal driving conditions is obtained,and the distribution characteristics and the impact of this special section on the driving behavior are further analyzed.The results show that,as the clear distance from the tunnel exit to the interchange decreases,the vehicle diversion time decreases and the diversion process becomes more rapid.At the starting point of the diversion,the vehicle diversion time on the left lane is obviously less than that on the right lane,resulting in greater driving risks.

关 键 词:隧道出口毗邻互通路段 驾驶行为 分流时间 车道位置 差异性
