Abstract: As the increasing building space and geometric complexity in modern building, the population is increasing greatly, which brings concerns about safety evacuation. The agent-based modeling and simulation (ABMS) is one of the most significant advanced techniques for evacuation analysis. This study focuses on the fire evacuation simulation in the Block Z of Hong Kong Polytechnic University by modeling using an evacuation program FDS+Evac, which is developed based on ABMS. For an appropriate application of the software in evacuation simulation, theoretical backgrounds of modeling techniques and literature reviews have been studied. Field study of the research building was conducted and basic geographic data was captured. Besides, the properties and behavior rules of agents during evacuation were analyzed and used in the computer simulation. In the simulation progress, different scenarios were established and the results show the density of population, the number of evacuees and the number of available exits, as well as the interaction of fire may all affect the evacuation performance. For Block Z of Hong Kong Polytechnic University, eight exits are enough for emergency evacuation in the whole building. The efficiency of evacuation can be improved by increase the width of doors and corridors or reduce the density of population at the places which block may occurred. Therefore, the agent modeling is a useful way to simulate emergency evacuation. It can be performed to evaluate evacuation safety during emergency, which is not only significant for design stage but for late proposals.
