The invention belongs to the technical field of urban traffic planning, and particularly relates to an OD-clustering-based urban rail transit passenger flow corridor identification method and application thereof, the OD-clustering-based urban rail transit passenger flow corridor identification method carries out OD point clustering processing based on prepared and preprocessed data, and proposes unique clustering variables for OD clustering; according to the method, an O point distance, a D point distance and a path overlap ratio are considered, a reasonable proportion is set, influence factors of passenger travel behaviors are reflected more intuitively, an OD amount is used as a weight of a clustering sample point in a clustering process, the accuracy and reliability of OD clustering are ensured, two clustering center points, namely an O point and a D point, are selected in a clustering center point selection stage, and the accuracy and reliability of the OD clustering are ensured. According to the method, the passenger flow volume is distributed to different paths between two clustering center points of the point O and the point D, so that the urban rail transit passenger flow corridor can be quickly and accurately identified, and a decision basis is provided for planning layout of rail transit lines and cross-line operation of rail transit trains.
本发明属于城市交通规划技术领域,尤其为一种基于OD聚类的城市轨道交通客流廊道识别方法及其应用,该基于OD聚类的城市轨道交通客流廊道的识别方法基于准备与预处理的数据进行OD点聚类处理,并提出针对OD聚类独特的聚类变量,将O点距离、D点距离和路径重合度都考虑在内并设置合理比重,更直观地反映了乘客出行行为的影响因素,在聚类过程中将OD量作为聚类样本点的权重,确保OD聚类的准确性和可靠性,该方法在聚类中心点选取阶段,选出O点和D点两个聚类中心点,通过将客流量分配到O点和D点两个聚类中心点之间的不同路径上,实现快速准确地识别城市轨道交通客流廊道,为轨道交通线路的规划布局和轨道交通列车跨线运行提供决策依据。
