互通式立交间距约束型出口安全对策分析

Analysis on safety response of interdependent interchange with spacing restricts

从隧道出口驾驶员的"明适应"、驾驶员对立交出口位置的识别等方面进行了研究,提出了基于"明适应"的隧道与互通式立交出口需要的最小间距值,并结合变换车道需求,根据交通标志设置及交通条件确定两个立交之间的最小间距值,并对间距约束型的立交出口问题提出安全对策。

This paper studys on the driver's"bright adaptation"of the tunnel exit and the driver's identification of the exit position of the interchange,and proposes the minimum distance between the tunnel and the interchange exit based on the"Ming"adaptation.Combined the change lane demand,according to the traffic sign setting and the intersection conditions,the minimum distance between the two interchange is determined.The safety response is put forward for the exit problem of spacing constrained interchange.
