摘要
为高效地管理城市道路交通信息以及可视化地分析道路交通资源,开发了基于地理信息系统(G IS)的城市道路管理系统.该系统以G IS为平台,用点、线、面等空间对象表示道路交通管理信息的空间位置,用空间对象的属性表表示道路交通管理信息的特征.同时在G IS平台上开发了人机交互界面,实现了道路交通管理数据的加工、编辑、查询、显示及打印.最后基于道路网和道路交通管理信息开发了道路交通资源分析系统,并在实际应用中取得了良好的效果.
Based on geographical information system （GIS）, a system is developed to manage urban road traffic information with high efficiency and analyze road traffic resources visually. In the system road traffic control information is represented by graphic objects such as points, lines or regions in GIS, while the specifications of them are stored in the attribute table of the objects. Moreover, GU interfaces are developed to process, edit, query, display and print the information. Finally a road traffic resources analysis system based on road network and traffic control information associated with them is developed, and it gains the better efficiency in practice.
