摘要
为了合理确定小城市道路网级配,以城市道路资源的供给量最小为目标函数,从小城市的道路等级、功能及其横断面形式入手,以道路总里程、交通供需匹配关系、道路容量及道路面积需求等作为约束条件,建立了小城市道路网的合理道路级配模型,运用道路级配模型对上虞市道路网进行了分析。分析结果表明:主干路、次干路与支路最优道路级配计算值为1.00∶1.56∶2.56,实现了小城市道路资源的优化配置,说明小城市道路网的合理道路级配模型是合理的。
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. 8 tabs, 13 refs.
