基于轨迹相似性的轨交乘客特征评价方法
Evaluation Method of Rail Transit Passenger Characteristics Based on Trajectory Similarity
摘要
Abstract
In urban rail transit,the operator collects and analyzes the trajectory data of passengers,obtains and classifies the travel patterns of individuals or groups,optimizes the resource allocation according to the travel characteristics of passengers,and improves passenger satisfaction.To obtain the characteristics of rail transit passengers,this study considers passenger travel trajectories in subway networks,depicts travel trajectories with highly overlapping stations as similar,and designs a trajectory similarity evaluation algorithm.Based on this evaluation,a method for evaluating passenger characteristics is proposed and the similarity matrix of passenger travel trajectories during a period is obtained.The similarity matrix is further optimized to obtain the travel pattern matrix for passengers.In this study,experiments are conducted using real-world data from the Automatic Fare Collection(AFC)system in Shanghai.The results demonstrate that the proposed method is applicable to both individual passengers and groups.Among the 10 000 randomly selected passengers,4 386 meet the travel frequency standards and regularity requirements.Additionally,the travels of regular passengers account for 67.85％of all travels.关键词
