By summarizing the common methods of safety assessment , the author presents the typical process of mass transit system risk analysis , and discusses the contents of risk analysis 摘要简要归纳了安全评估的常用方法；总结出了轨道交通系统风险分析的一般过程，并讨论了风险分析的内容。
The outset of urban railways traces back to more than one hundred years ago , however , until the 1970 ’ s it began to attract the attention of people thus expanded in a large scale 城市轨道交通的诞生和发展已有一百多年的历史,但重视和大规模修建城市轨道交通系统则是在20世纪70年代以后。
The urban rail transit systems of berlin and cologne in germany are introduced , and some experience in the planning , design and operation of urban rail transit system is summarized 摘要在介绍德国柏林市、科隆市城市轨道交通系统基础上，总结在城市轨道交通系统规划设计与运营中值得我国借鉴的经验。
Century is a peak period for urban railway development in big cities in china , and now there are more than thirty cities in this team . it is obvious that a golden time for urban railway construction has come 进入21世纪,我国大城市的轨道交通正逐渐进入一个建设高峰时期,目前全国已有30多个城市计划修建城市轨道交通系统,可以说,我国目前城市轨道交通建设逐步呈现出火热状态。
The fuzzy analytical hierarchy process ( fahp ) method is applied to carry out qualitative and quantitative analysis for those functional factors in emergency rescue process and an evaluation model is built based on the theory of system engineering 从系统工程理论的角度，采用模糊层次分析法对影响应急救援过程的多个功能要素做定性和定量分析，建立评价指标体系，应用轨道交通系统实例进行综合评价。
The software not only displays an operating map of the railcar system but also simulates its physical and logical features including system layout , driving control , data communication , management , services and failure handling , etc 所完成的软件不仅要显示轨道交通系统的运行图，而且要尽量逼真地模拟其物理状态和逻辑状态，从系统布局、行驶控制、数据通信、运营服务、故障处理等多方面来体现一个真实系统的实际状况。
The author analyses the typical rail transport system abroad compared with the present chinese rail transport planning , discusses its fundamental function , system design and the problems such as the priorities of its construction and the passenger traffic forecast 结合我国轨道交通规划的实际，分析国外典型城市的轨道交通系统，探讨了轨道系统的功能定位、网络设计，和轨道项目的建设排序及轨道客流预测分析方面的问题。
Based on analysis of the transportation conditions of new york , tokyo , london and paris , this paper clarifies the transportation demanding characteristics in modem international metropolitan , the adaption of rail transit system as well as the city transportation structure 摘要通过对纽约、东京、伦敦、巴黎四个国际大都市进行对比分析，阐述现代国际大都市圈交通需求的特点、轨道交通系统的适应性以及轨道交通对于城市交通结构所产生的影响。
Base on the concept of system ' s reliability , this paper makes a series of reliability index for urban mass transit ( umt ) safety , clearly defines these indexes , such as operational reliability , operational maintainability , and operational availability , discusses the calculation method of them 摘要基于系统可靠性概念，构建了城市轨道交通系统的可靠性指标体系，提出了运营可靠度、运营恢复度及运营利用率等指标的定义，给出了相应的计算方法。
To ameliorate the public traffic problems , the perfect urban rail transport systems have been developed in many developed countries except the traditional road traffic , which have formed a solid urban rapid rail traffic network including ground , underground and over - ground 改善大城市的公共交通问题，除传统的地面轨道交通外，许多工业发达国家都大力发展较为完善的城市轨道交通系统，形成一个由地面、地下和空中组合而成的立体式公共交通网。
