  • In order to determine the appropriate road grade in small city, the supply minimum of urban road resources was taken as objective function, the rank, function and cross section of urban road were considered, total road length, traffic supply-demand matching relationship, road capacity and road area supply were taken as constraints, a reasonable road grade model of road network in small city was put forward, and road network in Shangyu City 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 in the city is 1.00∶1.56∶2.56, which indicates the optimization of road network in the city, and the model is rational.
