摘　　要：旨在提出一套科学性、操作性、实用性强的城市轨道交通车站分布优化方法。基于一个模拟实际情况的案例,利用计算机编程和数值计算平台MATLAB,编写实现获取城轨车站分布最优方案的程序,验证基于遗传算法的城轨车站分布优化方法的可行性;分析在实际操作中较不合理的评价指标取值,并进行改进。在实际应用中,这套程序可适用于各种给定备选点和必设点而从备选点中选择合理车站位置的情况。This paper aims to put forward a scientific,operational and practical optimization method of station distribution of urban mass transit(UMT).Based on a case that simulates the actual situation,the programming and numeric computing platform named MATLAB is used to write a program for obtaining the optimal scheme of station distribution of UMT,which verifies the feasibility of the optimization method of station distribution of UMT based on genetic algorithm.The unreasonable evaluation index values in actual operation are analyzed and improved.In practical applications,this program can be used to select reasonable station locations from given alternative stations and required stations.
