Data analysis of blocked road information based on GIS

Based on GIS technology, a spatial data analysis method for blocked road information data is presented in this paper. First, blocked road information data is introduced. Second, based on GIS technology, the blocked road information data analysis process is proposed. In which, simplify the processing of spatial data, isometric transformation based GIS platform, segment split processing, stake assignment, space matching of blocked road information data, and so on, are included. Finally, the method proposed in the paper is validated by blocked road information data of a province in eastern China from 2010 to 2013. The results show that the method is feasible and effectively, the analysis results can provide support for choosing highway network monitoring sites position, emergency material reserves and management.
