IIn the safety design of marine systems, it has to justly give a matter over human life in the case of outbreak of a marine accident such as fires and collisions. It may be difficult to establish a safe evacuation system by the cause of uncertain behavior of evacuee that is terrified under the stimulus by accident, should be considered in the redundancy system for safe evacuation. Accordingly, the safe evacuation system with the intention of securing evacuation routes and reducing escape time, is desirably designed by grasping the personnel behaviors can be predicted by using the proposed walking model with individual capacity of visible length and avoidance process for obstacles. Further, the mathematical model of psychological intelligence process in an emergency is contrived herein, in which the evacuation movement is simulated in the consideration of the decrease of walking speed and the occurrence of self-isolation in psychological action according to the magnitudes of accident stimulus. By applying these models to common space in a dinning cruise ship, taking account of the human factors with psychological action is rather valued in the safe evacuation system and the validity of the proposed models can be confirmed.
