基于断面匹配度的苏州地铁2号线交路组织方案研究

Research on Routing Organization Scheme of Suzhou Metro Line 2 Based on Section Flow Matching Degree

交路组织是城市轨道网络化运行的重要方式,能够满足复杂的客流需求。断面客流作为运力设置的重要依据,影响轨道运营对列车运行组织方案的制定。论文以苏州轨道2号线为研究对象,综合断面匹配度和乘客等待时间构建目标函数,明确约束条件并设计了精英遗传算法,最终确定其交路组织运行方案。结果表示2号线早高峰开行以陆慕站至桑田岛站为小交路,以全程为大交路的大小交路模式更为合适。论文提出的方法能够较好地直接应用于线路交路组织方案的制定过程。

Routing organization is a key way for urban rail transit operation to meet the complex passenger demand.As an important basis for capacity setting,section passenger flow affects the formulation of train operation organization scheme by track operation.Taking Suzhou rail line 2 as the research object,this paper constructs the objective function of section matching degree,defines the constraints,designs the optimization algorithm,and finally determines its routing organization and operation scheme.The results show that it is more appropriate for line 2 to operate in the morning peak with Lumu to Sangtiandao station as the small route and the whole process as the large route.The method proposed in this paper can be directly applied to the formulation process of line routing organization scheme.
