基于遗传算法的地铁车站引导标识布点探析
Analysis of Position Settings for Oriented Identifies of Subway Station

鉴于地铁车站乘客引导标识的重要性及其布设的复杂性，本文提出通过标准遗传算法来解决车站引导标识布点问题，同时归纳出遗传算法的三大步骤和实施的关键点，并以郑州地铁1号线中的“五一公园”站为例，以乘客诱导量最大为目标函数，同时设置多个约束条件，并利用现场客流量图转化为算法所需要的相关数据，利用VB编程计算出布点，并对结果进行稳定性分析，最终获取引导标识较为合理的布点，进一步提高乘客的进出站效率。
The layout of passenger guide sign in subway station is important and complex. This paper proposes a genetic algorithm to solve the passenger guide sign layout problem. Wuyi Park station of Zhengzhou subway line 1 is taken as an example. The passenger guided quantity is set as the objective function and various constraints are considered. The used data are taken from the site passenger flow diagram. The experiments are conducted to find out the optimal layout and the stability of the results is also analyzed, The results that the used method is able to generate reasonable layout and the efficiency of the entry and exit is improved as well.
