The Security Management Information System of Subgrade and Pavement Based on Grid GIS

There are lots of factors produce an effect on subgrade and pavement, these influence may directly relate to the security of transportation. According to the influencing factors for the security of subgrade and pavement, the author suggests that we should build a security management information system based on Grid GIS. The paper introduces the characteristics and structure of the Grid GIS at first; Then mainly describes the security management framework of subgrade and pavement based on Grid GIS; Finally discusses the implementation and application of this security management information system. It has profound significance to build highway subgrade and pavement information system security management system based on Grid GIS.
