摘　　要：我国高速公路联网收费数据覆盖范围广、质量较高,具有很高的利用价值。本研究借助部级高速公路运输量动态监测系统,以构建收费站和高速公路路段信息采集、整理及更新机制为基础,使用ArcGIS和TransCAD等软件搭建了高速公路流量分配路网模型,并基于TransCAD的交通流分配功能,利用全有全无分配原理实现了高速公路流量分配,将高速公路联网收费数据在高速公路路网上铺展开来,为分析路网运行情况、区域经济发展情况等相关研究及进一步的数据挖掘提供了技术支撑。Because of wide coverage and high accuracy, highway network charging data have great value in use. With the help of China Highway Traffic Dynamic Monitoring System, based on establishing an information collection and updating mechanism of toll stations and highways, the study builds highway network model by ArcGIS and TransCAD, and creates the technique of highway traffic assignment using all or nothing method in TransCAD. By assigning the network charging data to highway network, the study provides technical support for researches like network operation situation analysis, regional economic development analysis and further data mining.
