基于IC卡数据挖掘获取公交OD矩阵的方法

以广州市羊城通IC卡以及广州市公交系统信息为例子,探讨了实现基于IC卡信息获取公交客流出行特征的方法。在IC卡数据挖掘和统计基础上,对线路站点OD矩阵、区域OD矩阵进行了推算。相比传统的人工统计法。该方法易于实现,能运用到实际中且运算效率高,适用于海量数据的客流出行特征统计分析。

A Way to Get Bus Regional OD Matrix Based on Mining IC Card Information

Many scholars tried to obtain passengers＇ travel characteristics through the public transit IC cards.However,almost all of them met difficulties in dealing with the massive data and combing the public transit IC cards with the GPS system.Taking the IC cards used in public traffic information system of Guangzhou for example,a method of obtaining travel characteristics of bus passengers based on IC cards is discussed in this paper.On the basis of mining technology and gathering statistical data from public transit IC cards,bus lines OD matrix and regional OD matrix are obtained.Compared with the traditional artificial statistics,this method is easy to implement and can be applied to statistical analysis of passenger travel characteristics with high efficiency from huge amounts of data.
