An Agent-Based Evacuation Model to Support Fire Safety Design Based on an Integrated 3D GIS and BIM Platform

摘要

In this paper, a basic Agent-based evacuation model is constructed firstly. On the basis of the integration of evacuation simulation model and CFD (Computational Fluid Dynamics) fire simulation model, a simulation model for occupant evacuation in fire environment, is proposed. Then, a powerful platform which can be adopted to incorporate BIM into 3D GIS is presented and the simulation scenario of occupant evacuation in fire environment can be implemented effectively on it. The research demonstrated that it is possible to transfer (high level of geometric and semantic) information acquired from IFC-based BIM models into the 3D GIS environment. The results also demonstrated that the 3DGIS-BIMs integration platform provide a sufficient multi-level and amount of geospatial and indoor information for the seamless data fusion and management tasks to support the fire response management processes considering both indoor and outdoor situations.
