Bioterrorism simulation and risk assessment in 3D micro-spatial environments
Anthrax Letters after the 9/11 incident marked the bioterrorism has become a real threat. With the development of modern molecular biology, the manufacture of biological weapons does not need a lot of money or modern laboratories, and bioterrorism also do not need special training also. How to respond to bioterrorism in the crowded area of city, model the potential attacks, carry out efficient risk assessment, and develop a rapid and effective evacuation plan have become challenges in urban management. Using the basic theory of Virtual Geographic Environments and and human oriented GIS, combined with pathogen diffusion model and crowd simulation modeling techniques, this article aims to explore the methods of bioterrorism simulation and risk assessment in 3D micro-spatial environments. Multi-level grid based spatial data model, multi-hierarchy path finding algorithm, and the methods of combining cellular automata and multi-agent system are put forward. Taking the Olympic Park station of Beijing Metro Line 8 as a typical study area, a simulation and visualization system is implemented, and experiments are conducted in three scenarios. In the experiments, the exposed population in polluted areas, the optimization evacuation plan, the key monitoring area, the number of infected people and so on can be obtained at every computation step for supporting rapid and efficient emergency decisions in different simulation scenarios.
