| Abstract: | The GIS-based major road infrastructure safety management system was analyzed.The requirements of the system for the spatial information database were proposed.The structure and data model of the spatial information database were designed,and the information of spatial features was coded.The spatial information database was created with ESRI Geodatabase.As a result,the search speed and calculation accuracy of the system as well as the compatibility between the similar databases were improved. |
