Review of Urban Rail Transit Ticket Clearing Methods

［Objective］With the rapid development of urban rail transit, many cities have formed rail transit line networks with multiple operating entities, and have integrated around public transportation payment methods such as "one-card" and virtual QR codes to form a larger urban transportation network. As the core of connecting all kinds of transportation networks, the ticket clearing for urban rail transit line network is especially important. It is necessary to provide a more reasonable clearing method for the construction and design of ticket clearing systems for relevant cities in China. ［Method］Through an introduction to urban rail transit ticket clearing schemes in both domestic and foreign cities, the ticket clearing methods for multi-line travel in major Chinese cities are analyzed and compared, and the applicable ticket clearing method is selected through analyzing the advantages and disadvantages of the clearing models and algorithms. ［Result & Conclusion］The one-ticket transfer model commonly used in China relies only on OD (origin and destination) for checking records, making it difficult to fairly and reasonably distribute the fare to multiple operating entities that may be involved. A more scientific and reasonable clearing scheme needs to further strengthen big data research on the AFC (automatic fare collection) system, and more importantly, relying on existing technologies and computing models is required to strengthen the real-time analysis and overtime prediction accuracy of passengers′ path selection behavior, so as to enable the clearing mechanism accurately make adaptive dynamic adjustments according to actual operating conditions.
