The paper firstly elaborates on the calculation principles of the main line system capacity analysis, including the calculation of interval train track, safety braking distance, safety protection distance, safety distance, train average travel speed and so on.

然后详细阐述了正线系统能力分析的计算原理，包括列车追踪间隔的计算，安全制动距离、安全保护距离及安全距离的计算以及列车平均旅行速度、全周转时间和运用车配车数的计算。

Analyzed the output data, and find out the key factors influencing the capacity coordination, fitting the relationship between the number of departure line, the time interval of trains arrival and the rate of train running delay.

对输出数据结果进行分析，找出影响能力协调的关键因素，将到发线数目、列车到达强度和列车运行延误率、区间&车站最终通过列车数之间的相互关系进行拟合。

With shortening of the interval of the train following, some complex phenomenon of rail traffic flow have more and more impact on traffic safety and line capacity, such as the mutually influence of trains, train following operation and delay propagation of trains.

随着列车运行间隔的不断缩短，列车间相互作用、列车追踪运行、列车运行延误以及列车延误传播等轨道交通流现象对行车安全和线路通过能力的影响不断扩大。

This paper analyzes train headway in urban rail transport system, and puts forward three factors affecting train headway including safe spacing, cutoff interval and traffic flow.

通过对城市轨道交通系统中列车间隔的分析，提出了影响列车间隔的3大因素：安全间距，车站停留时间和运行裕量。

The validity of the model is tested through the comparison between the minimum time interval between trains spaced by automatic block signals and the theory value as well as the analog value of the maximum speed of the train.

通过对列车最小追踪间隔时间与列车最大速度的理论值和模拟值的对比，验证了该模型的有效性。
