摘要
地理信息系统为公路交通规划提供了基本数据库,也是进行公路交通网络分析的有力工具及交通规划分析结果表达的优良平台。文章探讨了地理信息条件下适合于公路网络拓扑结构的计算机表达方式,并在此基础上分析了最短路径基本算法在公路交通规划中的适用性,勾勒出在地理信息系统支撑下求解公路交通规划中最短路径问题的框架。
The geographic information system provides basic database for road traffic planning.It is a powerful tool for highway transportation network analysis and excellent platform for transportation planning analysis results expressed.The article discusses the computer expressions suitable for the highway network topology under the conditions of geographic information,and analyzed the applicability of the shortest path algorithm in road traffic planning,sketched out the framework for solving the shortest path problem of road traffic planning in the geographic information system support.
