摘　　要：在探讨城市轨道交通车站出入口布局规划总体原则和研究范围的基础上,基于GIS(地理信息系统)平台建立了车站出入口布局研究范围内GIS数据库,提出了车站备选出入口选取原则和车站出入口布局备选方案生成方法。以社会总成本最小为优化目标,利用遗传算法原理实现了车站出入口布局最优方案的求解,并通过案例研究说明了本方法的可行性。On the basis of discussing the general principle and research scope of entrances and exits layout planning of urban rail transit station,the GIS database of station entrances and exits layout planning is established on the GIS platform,and the selection principle of alternative station entrances and exits and the generation method for the alternative schemes are put forward.With the optimization objective of minimizing the total social cost,the genetic algorithm principle is used to work out the optimal layout scheme of station entrances and exits,and the feasibility of the layout planning method is verified with case study.
