摘要
面向地铁运营状态的动态性、不确定性及多因素动态关联性,采用路网运营仿真技术,基于路网客流分布状态变化,从网络整体角度研究地铁运营协调性的定量分析方法.将运营协调决策问题分成资源配置、服务设计、客流控制三个层次,提出利用运能需求匹配度,将系统不同层次的协调性进行关联分析的思想.从运输单元运能需求匹配度的均衡性和换乘服务效能两个方面构建网络运营协调性分析指标,给出基于分布熵的协调性指数计算方法.构建地铁路网运营中观仿真模型,给出面向协调性研究的路网仿真实验流程.最后,以北京地铁为例,进行案例研究,利用路网客流分布仿真实验数据分析两条线路的运营协调性,给出优化后的列车开行间隔.
The quantitative analysis method of metro network operation coordination is researched from the perspective of the overall network system. For the dynamic, uncertain and multi- factor dynamically associating characteristics of metro operation status, the operation coordination is analyzed based on network passenger flow distribution state, by using network operation simulation technology. The coordination analysis method based on multi-level capacity-matching-demand is studied, and the network operation coordination analytical indexes are built from two aspects of the capacity-demand balance between network transportation units and the transfer service levels, and the computing method of coordination indexes based on distribution entropy is introduced. The experimental methods and processes for analyzing the coordination based on the metro mesoscopic network simulation model are studied. Finally, a case study is conducted by taking Beijing subway as an example.
