基于高铁余票数据的客流分析模型研究

针对高铁余票的时间性和相对性两个特点,提出在特定时间点上利用相邻高铁站点间余票量不受其他高铁站点购票影响的特点,建立了高铁站点的上下净客流量分析模型。重点阐述了模型实现的5个关键技术:余票抓取规则、大数据量处理、异步访问控制、系统容错机制以及数据读取分析。最后,以常州市的几个高铁站为例做具体说明。

A Passenger Flow Analysis Model Based on the Remaining Ticket Information of High-speed Rail

The high-speed rail remaining tickets holds these two features: time and relativity.In a specific time point, the amount of remaining tickets between two adjacent high-speed rail stations will not effected by buying behavior of other stations.Then, a net passenger flow analysis model is proposed based on the information of the high-speed rail remaining tickets.This paper elaborates five key issues for the model implementation.These five issues cover the rule for capturing the remaining tickets, the large data processing, the asynchronous access control, the system fault tolerance mechanism, and the data reading analysis.Finally, it takes some high-speed railway stations in Changzhou city as an example to illustrate the model implementation.
