为进一步增加行车密度、提高客车速度,探讨在繁忙自动闭塞双线区段,不同信号显示制度对列车追踪间隔的影响,分析缩小列车追踪间隔的条件、措施和效果是具有现实意义的。为此,本文拟通过不同牵引类型、不同列车重量、不同坡度诸条件下,自动闭塞采用三显示及四显示列车追踪间隔的计算,分析自动闭塞信号显示制度对列车追踪间隔的影响。 In order to further increase the driving density, increase the speed of passenger cars, and explore the influence of different signal display systems on the tracing intervals of trains in the busy and automatically blocked double-line sections, it is of practical significance to analyze the conditions, measures and effects of reducing train tracing intervals. Therefore, this paper intends to calculate the tracking interval of the three and four display trains by different types of trains, different train weights and different slopes, and analyzes the influence of the automatic blocking signal display system on the train tracking interval.
