Abstract: The 2D cellular automata (CA) random model is applied to occupant evacuation considering the influence of human psychology and behavior. Thereby, we put forward some new viewpoints on the performance-based design of building exits: the exit width must be bigger than a certain critical value to ensure a dilute state of evacuation; the optimal value of the exit separation f is independent of the exit width d, but is related to the total width of the building D: f approximate to 0.3D; a symmetrical layout of the exits should be applied; Bad random factors will occur and lead to a prolonged and fluctuated evacuation time when the value of f is too small.
