摘　　要：本文提出一个两阶段的城市公交枢纽布局优化方法,该方法首先从备选点易达度、公交线路聚集程度和公交线路的分布范围评价其魅力度,进而确定备选枢纽点集.基于备选枢纽点集,综合考虑乘客和运营者双方利益,提出一个以枢纽辐射域最大、枢纽间相似度最小和土地成本最少的多目标枢纽布局优化模型,并设计多目标遗传算法进行求解.最后,以大连市主城区的公交系统为例,对本文提出的模型和算法进行检验.通过实例分析发现,本文提出的备选枢纽筛选模型得到的备选点几乎涵盖了大连市主城区的主要集散点,表明以魅力度评价备选枢纽点的方法是可行的,可以有效地为枢纽布局优化提供较合适的搜索空间.同时,从枢纽布局优化结果看,本文提出的多目标优化模型可以兼顾枢纽的数量、位置和土地成本,优化结果也符合大连市的实际情况.In this paper, a two-stage method of transit hub location optimization is proposed. Firstly, alternative hub locations are determined by evaluating the attractiveness of each alternative location. The attractiveness of alternative location can be obtained by three aspects： the accessibility, the aggregation of transit lines and the layout of transit lines. Based on the alternative hub location set, considering the benefit of passenger and operator, a multi-objective model is presented to design transit hub location in a city. Then, a multi-objective genetic algorithm is also developed to solve the model. Finally, the data of Dalian city is used to validate the two-stage method for transit hub location optimization. The results show that the chosen alternative locations are almost cover main land use of Dalian city by using the attractiveness- based model. This indicates that the attractiveness-based model is a feasible and efficient way to determine alternative hub locations. Furthermore, the solution of the transit hub location optimization accords with the actual conditions of Dalian city. This indicates that the proposed multi-objective model and algorithm can consider the quantity, location and cost of transit hubs.
