中文摘要：

分析了城市轨道交通车站空间结构和设施设备特点,将其划分为车站-楼层-区域-设备的逻辑层次结构;利用面向对象（object oriented）建模技术,提出了一套简洁而灵活的方法：通过3种几何线型类和4种设施设备基元类,以组合的方式构建车站所有设施设备模型,进而构建整个车站的空间结构模型.此方法不但能够利用现有AutoCAD工程图精确而快捷地建立客流仿真地图,并且能够以矢量图形的方式实时显示仿真过程.

英文摘要：

According to the characteristics of the spatial structure and devices inside,a UTM Station can be divided into a hieratical structure of station-floors-areas-devices,for the sake of simulation.Based on object oriented technique,a concise and flexible modeling approach for UTM Stations is developed.All models of facilities and devices in UTM station are built by combining four geometric figure models and three facility component models,and then the simulation maps of large-scale stations are generated from AutoCAD drawings easily and accurately.Besides,vctor-based animation is displayed in real time during simulation.
