针对复杂的多路交叉口交通组织重构研究

打开文本图片集

摘 要：多路交叉口是指多条道路汇交于同一交叉口，是城市路网的重要节点，也是改善交通状况的重要手段，但由于多路交叉存在的特殊性，交通环境复杂以及交通流向不明确，存在一定弊端。文章结合象山县石浦镇渔港北路改造工程，浅析复杂的多路交叉口交通组织重构的设计方案，对城市多路交叉口交通组织重构提供有益的借鉴。

Research on Traffic Organization Reconstruction for Complex Multi-leg Intersections

Wang Liuna，Shi Xinlei

Abstract：A multi-leg intersection refers to a road junction where multiple roads converge at the same point. As an important node of the urban road network， it also serves as a crucial means for improving traffic conditions. However， the inherent particularity of multi-leg intersections leads to a complex traffic environment and ambiguous traffic flow directions， resulting in certain drawbacks. Combining with the reconstruction project of Yugang North Road in Shipu Town， Xiangshan County， this paper briefly analyzes the design scheme of traffic organization reconstruction for complex multi-leg intersections， providing beneficial reference for the traffic organization reconstruction of urban multi-leg intersections.

Key words：Multi-leg Intersection， Intersection Reconstruction， Roundabout Intersection

1 绪论

随着城市发展速度的加快，原有老城区道路存在交通流组成复杂，房屋密度大，交叉口多且无信号灯控制等问题，多路交叉普遍且交通混乱的情况已无法适应当前城市交通安全有效的发展方向。（剩余3048字）
