Framework of Spatial Decision Support System for Large-Scale Public Building Evacuation

Buildings or constructions are the basis of modern human life. While unexpected and sudden emergencies happen in large-scale public buildings bring great lost of wealth and casualties. How to control such extreme events and make efficient evacuation is quite a problem for emergency planners and decision makers. In this paper, a spatial approach based on exploratory spatial data analysis (ESDA) technology is described to build a Spatial Decision Support System (SDSS) for large-scale public building evacuation. Method and application of ESDA for building environment spatial risk appraisal is the core algorithmic model for environment analysis module and the basis of evacuation routing optimization. Framework structure of SDSS for large-scale public building evacuation is explicated. SDSS could not only bring emergency routing scheme for evacuees, but also provide reliable environment risk related spatial information for emergency management decision making.
