掉头车道设置在交叉口最右侧车道的应用—以黄山路-新大路交叉口为例

为了降低掉头车辆与其他车辆之间的冲突,保证交叉口整体通行能力和服务水平,在对常用掉头模式分析的基础上,提出将掉头车道与右转车道合并设置在最右侧的方法,并结合现场实际情况及交通运行特征,以黄山路-新大路交叉口作为案例进行应用分析。结果显示,掉头车道最右侧设置可以降低掉头车辆与其他车辆之间的冲突,在保证右转车辆正常通行的前提下,提高了掉头车辆的通行效率,对于保证道路通行畅通、行车安全有序起到了重要的推动作用。

Application of U-turn Lane Placement in the Far-Right Lane at Intersections: A Case Study of the Huangshan Road - Xinda Road Intersection

In order to reduce the conflict between U-turning vehicles and other vehicles and ensure the overall traffic capacity and service level of the intersection, a method of merging U-turn lane and right-turn lane in the far right was proposed based on the analysis of common U-turn patterns, then the Huangshan Road - Xinda Road intersection was taken as a case for application analysis combined with the actual situation of the site and the characteristics of traffic operation. The results show that the U-turn lane which set at the right turn lanes can reduce the conflicts between U-turn vehicles and other vehicles, improve the traffic efficiency of U-turn vehicles on the premise of ensuring the normal passage of right-turn vehicles, and play an important role in promoting the smooth passage of the road and the safe and orderly driving.
