The evacuation and smoke movement interactive simulation model has been developed to handle the evacuation of large populations of individuals with mixed abilities. The advantages of the model are: 1) to handle evacuation of individual evacuees considering variety of behavioral parameters, 2) to handle total evacuation in a multi-story building via the stairs, 3) to consider interactions between egress behavior and spread of smoke in a building. The system is a deterministic simulation program implemented by the agent-based computer language, Repast. The evacuation model consists of three sub-models; space model, human model and smoke model. Some case studies were conducted to verify validity of the model. It was confirmed that the calculated flow rate or density of a crowd almost agreed with the previously measured ones and the evacuation behavior under the smoke movement can be represented by the model.
