Crowd evacuation simulation for bioterrorism in micro-spatial environments based on virtual geographic environments

► An evacuation model for bioterrorism in 3D micro-spatial environments based on VGE. ► An agent-based individual model and a pathogen diffusion model used to model individual behavior and bioterrorism. ► A bioterrorism-oriented simulation prototype system that can be used to simulate different evacuation scenarios. ► The crowd evacuation simulation model can provide the real subway station with an efficient emergency decision making.
