摘要
动车组是高速铁路的稀缺资源,以最少的动车组输送尽可能多的旅客是铁路运营的一个重要目标。在阐述动车组运用研究现状的基础上,对高速铁路直达和换乘2种列车开行模式进行分析,进而提出基于列车接续网络的动车组交路计划优化模型,并运用该模型,以京沪高速铁路为例分析高速铁路列车开行模式对动车组运用的影响,即采用换乘策略能在一定程度上减少所需动车组数量,但达到一定换乘比例后,所需动车组数量和动车组利用率优化效果不明显。
EMU is a scarce resource of high-speed railway, delivering as many passengers as possible by using least EMU is an important object of railway operation. Based on expounding study status of EMU utilization, this paper analyzes two train operation modes of high-speed railway through including transportation and transfer transportation, and then, puts forward the optimization model of EMU routing scheme based on train connecting network. By using the model with Beijing-Shanghai high-speed railway as an example, the paper analyzes the influence of high- speed railway train operation mode on EMU utilization, which shows applying transfer strategy could reduce the number of required EMU to a certain extent, but the optimization effect of the required number and utilization ratio of EMU are not obvious after achieving a certain transfer proportion.
