一种缓解环路交通拥堵的工程改造措施

An Engineering Reconstruction Measure for Alleviating Traffic Congestion of Ring Road

摘要:

以北京市三环快速路分钟寺桥区以及双井桥区进出口疏堵改造工程为例，研究了将环路进出口由“先入后出”改造为“先出后入”对缓解道路拥堵产生的作用，通过工程改造前后的交通运行情况分析，得出进出口方式调整后减少了机动车在主路的交织，解决了节点拥堵问题，为快速路进出口形式的设计提供了重要参考。

Abstract:

Taking the entrance and exit blockage reconstruction project of Fenzhongsiqiao Area and Shuangjingqiao Area in Ring III Expressway of Beijing as an example, the effect of reconstructing the entrance and exit of ring road from"first in and then out" to "first out and then in" to alleviate the road congestion is studied. By analyzing the traffic operation before and after the project reconstruction, it is concluded that after the adjustment of entrance and exit mode, the interweaving of motored vehicles on the main road is reduced, and the problem of node congestion is solved, which provides an important reference for the design of expressway entrance and exit forms.
