Abstract: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.
