基于GIS的区域交通通达性模型的研究与开发

The Implementation of Traffic Understanding Model Based on Raster Data

介绍了基于栅格数据的区域通达性模型的设计和实现思路,提出了以GIS为基础平台,以地图为载体,整合各种资源,建立区域通达度模型的方法,讨论了基于栅格数据的最佳路径分析方法,综合考虑各种影响因素,通过计算最小累加费用值确定最佳路径。

This paper introduces how to design and implement a traffic understanding model based on raster data.It also puts forward the method to build a GIS-based traffic understanding model integrating all kinds of resources and using maps as a basic way of showing the data.It also discusses the algorithm of optimum route analysis based on raster data model,which considers different influences factors,confirms the optimum route through calculating that adds up expenses value minimumly.
