Research on Screening and Identification Method of Commuter Flow in Metro Card Data

摘要

Commuter flow is an important part of metro passenger flow; accurately identifying commuter flow, finding the current distribution characteristics and changing rules of passenger flow are of great significance to rail transit planning, daily driving organization, and operation management. In order to effectively identify commuter flow, this paper proposes a method for screening and identifying metro card data based on the screening set. Metro card data includes IC card, mobile payment, and other types of data; this paper analyzes all types of card data, summarizes the characteristics of commuter flow, and proposes a simple and reliable screening rule to screen and identify commuter flow data. Finally, this paper conducts an example study of commuter flow based on the card data of Hangzhou Metro Line 2, and the results show that the proposed method meets the actual requirements.
