高速铁路城际动车组列车运行图缓冲时间研究

Study on Buffer Time of High-speed Intercity EMU Train Diagram

针对影响高速铁路城际动车组运输效率的列车运行图缓冲时间合理分布问题,以高速铁路城际动车组列车运行图缓冲时间确定因素为主要研究内容,采用对铁路运输组织基本原理的分析方法,得出具有周期性特征的高速铁路城际动车组列车运行图适宜采用具有全日列车运行时段缓冲时间呈总体均匀分布,部分时段呈局部集中分布的结论。

Aiming at the problem of reasonable distribution of buffer time of train diagram affecting the transportation efficiency of high-speed intercity EMU,this paper takes the factors determining buffer time of train dia⁃gram of high-speed intercity EMU as the main research content,and adopts the analysis method of the ba⁃sic principle of railway transportation organization.It is concluded that the high-speed intercity EMU dia⁃gram with periodic characteristics is suitable to adopt the buffer time of the whole day train operation peri⁃od uniformly distributed,and some time periods locally concentrated distributed.
