Abstract: Construction of urban regional traffic network is the base of regional transportation planning,the regional traffic network has a wide range of data,its storage,display,and management process is very complicated.The GIS-T contribute to establish clear,visualized structure of layer for traffic network which has strong maneuverability.The construction method of regional traffic network based on GIS-T is discussed,which based on the regional case of Changsha Yanghuyuan,it realizes the visualization of regional network editing and processing of attribute data by integrating vectorial graph and database,visual inputting,modifying network-data and optimization of project are realized on the basis of TransCAD simulation platform.The information of network can be updated in time,the accurate and complete testdata can be offered for the planning and design of regional transportation network by means of GIS-T.

Key words: Geographic Information System for Transportation(GIS-T), regional traffic network, network representation and construction

摘要: 构建城市区域交通网络是进行区域交通规划的基础,区域交通线网数据种类繁多,其存储、显示、管理过程复杂。运用GIS-T技术辅助建立的交通网络层次清晰,直观性强且易于操作。结合长沙洋湖垸区域案例探讨了基于GIS-T的交通网络系统的构建方法,通过矢量图形和数据库相结合实现了区域网络编辑和属性数据处理的可视化,在TransCAD仿真平台上实现了网络数据的可视化输入、编辑及方案优化。借助GIS-T可以及时更新区域交通网络信息,为区域交通网络运输系统的规划、设计提供准确、完备的测试数据。
