摘　　要：针对中小城市公交线网的特点,提出了基于路线优选的公交线网优化方法。根据中小城市公交的实际情况,以线网单位效益最大为目标,并选择约束条件建立了中小城市公交线网优化模型。在进行线网优化时,将优化过程分解为公交站点合并、公交起讫站点的选择与配对、候选公交线路集的生成、线路优选几个步骤,降低了模型求解的难度。并针对各个步骤分别利用匈牙利算法、Yen算法和穷举法设计了相应的计算程序,使优化方法具备实际应用的可操作性。This paper presents an optimization method based on optimum route selection for small and medium-sized urban transit network.Firstly,according to the actual situation of transit system in small and medium-sized cities,by taking maximum unit benefit as the objective function and selecting some constrains,the paper establishes a transit network optimization model for small and medium-sized cities.During the optimization process,the transit network optimization is decomposed into four steps including merger of bus stops,line origin and destination stops selection and distribution,generation of candidate set of bus lines,and optimum route selection,which make it easier to find solution.For each step,computer program is designed to make the optimization method operable in practical application.
