摘　　要：针对优化规划城市公交线路网络布局问题,提出了一种以公交线路可达性为原则并基于蚁群算法的城市公交路线网络布局优化模型。首先将公交线路分为快线、普线和支线,分别建立目标函数模型及约束条件,然后引入蚁群算法对目标函数进行优求解,最后利用实例对以上方案进行验证。结果表明,构建的模型具有一定程度上的优化能力,可实现不同层面线路的优化。本研究的创新点在于从不同角度对公交线路进行优化,以此提高了线路的可达性,更好地提升了公交企业的服务水平。Aiming at the problem of optimizing the layout of urban public transportation network,this paper proposes an optimization model of urban public transportation network layout based on the principle of public transportation accessibility and ant colony algorithm.Firstly,the bus line is divided into express line,general line and branch line,and the objective function model and constraints are established respectively.Then the ant colony algorithm is introduced to optimize the objective function.Finally,the above schemes are verified by examples.The results show that the model constructed in this paper has the optimization ability to a certain extent,and can realize the optimization of lines at different levels.The innovation of this study is to optimize the bus routes from different aspects,so as to improve the accessibility of the routes and the service level of the bus enterprises.
