在客货混跑的单线铁路区段存在着会车等多种影响列车旅行速度的因素,通过分析不同速度列车间在行车过程中相互影响关系,并基于概率论研究这些作业对不同种类列车旅行速度的影响状况,提出在不同速度列车共同运行状态下的列车旅行速度计算方法,该方法可以计算在不同种类列车会车作业对列车旅行速度的影响(仅讨论会车),所得结果能够代表单线铁路列车运行特点,可以作为无统计信息情况下(如铁路设计、改造等)的旅行速度方面的数据参考。
There are many factors that affect the speed of train travel, such as meeting cars, in the single-track railroad running on both passenger and freight. By analyzing the interaction between different speed trains in the driving process and based on the probability theory, this paper studies the effects of these operations on different types of train travel The paper puts forward the calculation method of train travel speed under the condition of common running of trains with different speeds. This method can calculate the influence of train operation on the train travel speed by different types of trains (only discuss the train), and the result can represent the single line The characteristics of the railway train operation can be used as the data reference for the travel speed without statistical information (such as railway design, renovation, etc.).
