摘　　要：利用电子收费数据进行统计和数据挖掘,可对其所呈现出的交通特性进行深度分析并有效应用.基于我国西部某高速公路的电子收费数据,利用数据管理平台,构建交通主题数据仓库,统计高速公路交通流量的时变、日变、周变规律,以及分车型、节假日及工作日流量变化规律;并对电子收费用户的出行特征进行分析,计算了各路段交通流量,统计各收费站OD交通发生吸引量及收费站间的交通分布量,也分析了车辆的行程速度及分布规律,从而了解了该高速公路的交通流特性,为高速公路电子收费数据的统计分析提供了借鉴方法.Based on an Electronic Charge data of an expressway in west China,traffic data warehouse was built by use of SQL Server which is a platform for data management.The laws of traffic flow on hour variation,daily variation,week variation,vehicle types,holiday and working day were analyzed.The traffic trip rule of the Electronic Charge users is found,and the traffic volumes of every road section,traffic generation,traffic attraction and distribution of toll stations are calculated.The travel speed and its distribution law were summarized.It is helpful to understand the traffic flow character of the expressway.The analysis method can also be referential to mine Electronic Charge data of similar expressways in China.
