摘　　要：利用高速公路全样本量数据进行统计和数据挖掘,深入分析交通流特性可用于解决实际交通问题.基于大数据平台建立交通流数据库,统计处理高速联网数据,利用交通分配软件搭建流量路网分配模型,研究乘用车出行的区域分布及路段流量分布特征,对比了节假日与工作日的流量特性差异,并对出行距离进行了分布函数拟合,探究了辽宁省高速公路乘用车出行的交通特性,有助于高速公路的规划管理,为区域交通流的研究提供了借鉴方法.By employing expressway network toll data for statistics and data mining,the analysis of traffic flow characteristics can be used to solve practical traffic problems.The traffic flow database was established based on SQL platform in order to statistically process highway network toll data.The traffic network distribution model combining traffic flow and high-speed road network was built by Trans-CAD to study the regional distribution and road traffic distribution characteristics of passenger vehicles travel.The difference of traffic characteristics between holidays and working days was compared,and the travel distance was fitted by the lognormal distribution.The traffic characteristics of passenger vehicles travel on the expressway in Liaoning Province were analyzed.which is helpful to the planning and management of expressway and provides a reference method for the study of regional traffic flow.
