番禺西环路与禺山西路交叉口改造方案研究

Study on Reconstruction Scheme of Intersection of Xihuan Road and West Yushan Road in Panyu District

针对广州市番禺西环路与禺山西路交叉口改造问题,结合区域发展、功能定位、现状条件等多种因素,对交叉口改造的制约性因素进行了分析。采用“四阶段”法,依据交通观测所得的现状路网流量等数据建立预测模型,对交通流量进行了预测。在此基础上通过多个设计方案的分析对比,选定了分离式立交改造方案。经过多轮专家论证,认为分离式立交方案符合交叉口实际情况,具备可实施性,同时为远期交通流量进一步增大预留了改造条件。

Aiming at the problems in the intersection reconstruction of Xihuan Road and West Yushan Road in Panyu District of Guangzhou City,combined with the regional development,functional positioning,current conditions and other factors,the conditionality factors of intersection reconstruction are analyzed.The"4-stage"method is used.The prediction model is established according to the data of current road network flow obtained by the traffic observation to predict the traffic flow.On the basis,the reconstruction scheme of separated interchange is selected by the analysis and comparison of many design schemes.After several rounds of expert argumentation,it is considered that the separated interchange scheme meets the actual situation of intersection,is implementable and also reserves the reconstruction conditions for the further increment of long-term traffic flow.
