论述列车自动驾驶 ( automatic train operation， ATO) 系统在城市轨道交通中的应用情况，说明其重要 性。为了评价不同厂家提供的 ATO 系统的综合性能， 需要建立一个对 ATO 系统评价的标准。对 ATO 系统 的运行可靠性、运行效率、旅客舒适度、能耗等进行研 究，并建立性能评价模型。利用北京地铁亦庄线 ATO 系统的实际运行数据，对该评价模型进行验证。结果 表明，该模型是行之有效的，可为建立 ATO 系统评价 标准提供参考。

In recent years，ATO ( Automatic Train Operation) system becomes more important because of its ever-increasing demand in urban rail transit systems． It is necessary to standardize the methods to evaluate ATO’s performance． In this article authors propose a method to comprehensively evaluate ATO’s performance， considering the reliability， efficiency，passengers’comfort and energy consumption and other factors． The method has been applied to assess the Beijing Yizhuang ATO system based on the actual data． Results indicated that the method is valid and effective．
