GIS技术在县域公路网规划中的应用

Application of GIS in County Highway Network Planning

GIS技术在县域公路网中的应用将会使数据资料的获取和管理更加系统、高效、准确,从而带来数据搜集、管理方法的革命性变化,同时GIS特有的对空间数据的存储、管理和分析功能也将实现公路网规划过程的可视化操作,给县域公路网规划带来极大的方便和好处。文中介绍了GIS在交通方面的应用现状及建立基于GIS的县域公路网规划信息系统的必要性,提出了基于GIS的县域公路网规划信息系统功能分析的方法,并对基于GIS的实现系统进行了介绍。

With the development of county economics,rapidity,convenience,comfort and diversification are necessary in highway operations,besides accessibility and feasibility on the basis of urban-rural integration.The satisfaction of traffic supply to demand is needed to be considered as well as real traffic and basic data in county highway network planning.The application of GIS can make data collection and management more systematic,efficient and accurate.Meanwhile,the specific storage,management and analysis function of GIS spatial data can realize visual operations in the process of highway network planning.The application status of GIS in transportation field was presented firstly.And then the necessity of information system was analyzed in highway network planning based on GIS with analysis method of the system function being proposed.Finally,the GIS-based implementation was illustrated.
