Research On The System Of Highway Hazard Management Based On GIS

In the long-time work of highway natural disaster prevention and treatment, highway management departments had accumulated abundant practical experience. At the same time, they had also collected and arranged plenty of highway disaster information. It was quite a big and onerous project to manage and analyze the information. This paper combined with one subject of western communications science and technological project named subgrade disaster prevention techniques extension and application demonstration .We had fully inducted and summarized the existing research results at home and abroad, and absorbed successful experiences of highway disaster prevention from various regions. Based on investigation, analysis and study, we had calculated out all kinds of highway disaster data in research area. We had also developed highway disaster management system based on ArcGIS. In this way, we could offer technology reference to develop highway disaster prevention all over the country.This paper had studied natural environment conditions and highway major disasters in the backing project area, and stated lots of data about highway disaster main types, characteristics, formation conditions, controlling factors, prevention and drainage measures. In order to store, treat, display and use these disaster information, we had used geographic information system(GIS) to establish highway disaster management system. The management work efficiency of highway disaster had improved significantly.Under the background of backing project highway disaster data, we had utilized Visual Studio 2005(VS2005) and VB programming language, combined with ArcEngine, to develop GIS secondarily. We had constructed the platform of highway disaster management system based on GIS, and completed the overall design of platform. It had achieved the functions of highway disaster management system of data management, display, query, multimedia demonstration and data output. The system has favorable, simple-operation user interface, extensibility and open nature. Highway disaster information can be stored centralizedly, managed uniformly, queried fast and obtained conveniently. It provides information sharing among reconnaissance and design institutes, all levels government management department, evaluation experts, and highway maintenance management department. In addition, it offers technical support for deeply study of scientific research projects.
