城市交叉口治堵设计方案分析

以海口市龙昆南路-城西路交叉口为例,结合海口市实际交通发展情况,对该交叉口进行交通现状分析.提出了硬化安全岛、增设进口道、左转中置、优化相位配时等交通治堵设计方案,并借助交通仿真软件Synchro,对设计方案的合理性和可行性进行了论证.

Analysis on Design Scheme of Congestion Control at Urban Intersection

Taking the intersection of Longkun South and Chengxi Road in Haikou as an example, combined with the actual traffic development of Haikou City, the traffic status of the intersection is analyzed. The traffic congestion control design schemes such as hardening the refuge island, adding the entrance lane, turning left center and optimizing the phase timing are put forward. The rationality and feasibility of the design scheme are demonstrated with the help of the traffic simulation software Synchro.
