A web-based spatial decision support system for effective monitoring and routing problem

This paper presents an integrated framework of Geographic Information System (GIS) and a Relational Database Management System (RDBMS) equipped with interactive communication capabilities. The model integrates the design of the database and the management of implementation of the monitoring system which includes the operations of query and analysis using the web and desktop applications. This study aims to apply techniques of analysis of the road network in a GIS to collect geographic data on the monitoring station and the roads. The information on road infrastructure is not only useful for locating monitoring stations, but it is also important to guide a station to follow the shortest path to achieve the objectives of management and routing. Optimal routes based on the minimum cost are identified using Dijkstra´s algorithm. The results show that it is possible to use an effective method of GIS to integrate multiple data sets and learn advanced information. The need for such a framework and requirements for the orientation of monitoring stations in the event of a road accident are studied and the architecture of this framework is discussed. The proposed system should be a tool comprehensible, well structured, efficient and scalable which facilitates the location of road accidents and the orientation of the monitoring stations in response to these accidents. Simulated test cases have been carried out for network of Mohammedia City in Morocco.
