Comparison of two models for human evacuating simulation in large building spaces

This paper presents the simulated results of human evacuation in a large space building. Two different models, Cellular Automata (CA) model and social force (SF) model are adopted. The simulated evacuation time and main characteristics of human evacuation are simulated and these results by the two models are compared. To check the practicability of the models for actual complicated cases, the simulating time is also compared. The results denote that both the two models can simulate the “arch” and “faster-is-slower” effect for human evacuation. It also could be found that the CA model is easily analyzed and possess fewer CPU time, while the SF model is much easier to be expanded to consider more complicated human behavior models.
