In order to explore the relationship between the urban road capacity and the type of cross-sectional layout, the traffic carrying capacity of each grade road in Rulehu district was studied.In order to fully reflect the interaction between the urban road network and the surrounding land use, traffic demand, on the basis of the known width of the proposed road red line,to design the cross-section layout of the road area.Using the traditional four-stage prediction method to carry out the simulation and prediction of residents travel, the predicted OD is allocated to the design of road network to test the operation of road network.According to the road network load degree and travel time index, the layout of the road cross-section is optimized, which is carried out repeatedly in turn, and finally to find the optimal layout of the road cross-section in the specific traffic conditions.The optimal layout type of cross-section of the road in Rulehu area provides a reference for urban road construction in the future, which is conducive to the rational operation of urban transport system.
