交通拥堵区域平面交又口渠化设计方法研究

摘要

In order to improve the capacity of the plane intersection in the traffic congestion areas, this paper studies the intersection broadening method in the light of entrance lane broadening, exit ramp broadening, corresponding relation of entrance lane and exit ramp and turning ramp design, etc., proposes the optimal design method for the traffic island at the intersection and analyzes the traffic at the intersection of East Shunjiang Road and Fengshan Road in Shangyu as a case in point. The result indicates that the method can be used in the intersection channeling.%为提高交通拥堵区域平面交叉口的通行能力，本文从进口道展宽、出口道展宽、进出口道对应关系和掉头车道的设置等方面对交叉口的展宽处理方法进行了研究，并提出了交叉口交通岛的优化设计方法，并以上虞市舜江东路一凤山路交叉口为例进行了案例分析，结果显示，本文所提出的方法在交叉口的渠化设计中能得到良好的应用。
