摘　　要：城市道路平交口连接隧道出口的位置是交通安全的重要风险点,为了确定城市道路平交口与隧道出口的合理间距,对驾驶员视觉适应距离、车辆制动距离、车辆变道距离和红灯期最大排队长度4个影响因素进行了分析,提出了不同设计速度下城市道路平交口与隧道出口的合理间距参考值,可为同类工程设计提供一定参考。The position of the exit of the tunnel connecting the urban road intersection is an important risk point for traffic safety.In order to determine the reasonable distance between the urban road intersection and tunnel exit,four influencing factors were analyzed,including driver visual adaptation distance,vehicle braking distance,distance for vehicle changing lane and the maximum queue length during the red light period.Uunder different design speeds,the reasonable distance reference value was proposed to provide some reference for similar engineering design.
