摘　　要：针对传统车辆OD矩阵获取成本高、过程繁杂的弊端,以高清智能卡口系统的车牌识别数据为研究基础,提出了基于Excel VBA的车辆OD矩阵获取方法,以常州市武进区的车牌数据为例展开研究,把每个卡口点位作为一个调查点,划分交通小区。利用Excel VBA对卡口记录的车牌信息进行数据挖掘获取各交通小区之间的车辆OD矩阵,导入TransCAD软件模拟现状交通运行,结果表明模拟的现状交通特征与现实中社会交通特征和人们的交通出行感受基本相符,此OD矩阵获取方法具有可行性。Concerning to the shortcomings of the traditional vehicle OD matrix such as high cost and complex process,with the license plate identification data of high-definition smart bayonet system as research basis,a method for obtaining vehicle OD matrix is propsed based on Excel VBA.Take the license plate data in Wujin District of Changzhou City as study object,each point bayonet is regarded as a survey point and traffic zones are divided.In order to obtain vehicle OD matrix between each traffic zone,Excel VBA is used to record bayonet of license plate information in order to investigate the OD matrix,and import these data to TransCAD software to simulate the current traffic running.The results show that the current traffic simulation running is basically consistent with the social traffic characteristics and the real feeling of people in travel,which proves that the OD matrix obtaining method is practicable.
