| 摘 要： | 针对单向双车道高速公路隧道与互通立交出口间距只能满足识别视距的情况，分析了车辆驶出隧道出口的换道过程，结果表明，在极端困难情况下，隧道出口的明适应时间能够缩短到1s?预期驶出高速的车辆必须在隧道前的路段完成变道，确保驶出车辆在车道外侧上行驶，才可以保证运营期交通行车安全。

| Abstract: | Analysis was conducted of the process of changing lanes through the exit of the tunnel when the distance between the one-way two-lane expressway tunnel and the interchange exit can only meet the requirements of the identification line of sight. Results show that the following conditions must be met in extremely difficult situations:(1)the light adaptation time at the exit of the tunnel can be shortened to 1 s; (2) vehicles that are expected to drive out of the expressway must change lanes before entering the tunnel to ensure that the vehicles drive on the curb lane to ensure traffic safety during the operation period. |
