Abstract
In order to determine the appropriate road network density and road grade,the maximum of road capacity and the minimum of road construction fund were taken into consideration to built an objective function.The road width was considered,traffic supply-demand balance relationship,road area control,spaces of different road classes and function of road were taken as constraints,a reasonable road network density model of urban high density developed regions was put forward,and road network in Zhenru Sub-centers of Shanghai was analyzed by using the model.Computation result shows that an optimal solution of road grade for main trunk road,secondary trunk road and branch road is 1:1.9:5.3,which indicates the optimization of road network in high density developed regions,and the model is rational.
