基于虚拟编组的均衡间隔列车运行图编制研究

论述虚拟编组技术对运输组织方式的影响，并对传统列车运行图编制进行研究，提出基于虚拟编组技术的均衡间隔列车运行图编制方法。明确虚拟编组技术下均衡间隔大小交路列车运行图编制的步骤，从服务水平和企业运营成本两方面确定列车运行图的评价指标，并采用层次分析法对不同方案进行评价。以北京地铁19号线为例，分析基于虚拟编组的等间隔列车运行图编制方法，结果表明此方法可提高服务水平、降低运营成本。

Using Virtual Coupling Technology to Develop Train Timetable with Equilibrium Interval

This study summarizes the influence of virtual coupling on organization of train operation and reviews the study of conventional methods of developing train running diagrams. Then, it proposes the development of the train timetable with equilibrium interval by using virtual coupling technology, and expounds specific steps of preparing such timetable. The evaluation indices are set up for assessing the train timetable in terms of service levels and operations costs. The analytic hierarchy process (AHP) is adopted to evaluate different train running schemes. Line 19 of Beijing Metro is taken as a case to test the efficiency of the timetable based on virtual coupling technology in service level improvement and costs reduction.
