[Abstract]:Geographic Information system (GIS) has been widely used in road traffic management. Road maintenance, as an important part of road management, uses spatial information collection technology and geographic information service technology to collect road maintenance information. The realization of road maintenance spatial information visualization, data statistical analysis and network analysis services, for improving the road maintenance response level and service capacity has an important significance and role. In this paper, the visualization model of road maintenance geographic information and the application of road maintenance geographic information system are studied and tested. The main contents are as follows: starting from the management and visualization of road maintenance information, the road data model is analyzed separately. The visualization of road information, the content of road maintenance information management, the application of road maintenance geographic information system and the research status at home and abroad are analyzed and studied. The analysis shows that the visualization model, method and application of road maintenance spatial information are important research contents in this field. The establishment of road maintenance representation spatial data model is the basis of maintenance data management and visualization. This paper analyzes the content and data characteristics of road maintenance data, the node-arc model and linear model of road network and the characteristics of cartographic representation technology, and combines the requirements of road network and road maintenance information expression. A road maintenance information representation model based on linear reference and a visual representation model of point, linear and plane road maintenance elements are established. Data management and visualization of road maintenance facilities is an important content of road maintenance GIS application. The road maintenance information data are divided into road traffic network data and road maintenance data, and the corresponding data content and data construction method are discussed respectively. Based on this, the method flow of road maintenance facility visual expression based on cartographic expression is designed, and the process of drawing point, line and surface road elements is discussed in detail. Based on the road maintenance representation model, facility data management and visualization method, the application test of road maintenance visualization GIS is carried out on ArcGIS platform. Road data were extracted from high-resolution aerial photography, and the application experiments of road maintenance visualization, road traffic network analysis, basic statistics of road maintenance data and analysis of road maintenance path events were carried out respectively. Finally, the paper summarizes the work and experimental results, points out the shortcomings and the aspects that need to be improved in the future.
