In case of emergency, such as an earthquake or a fire, we will manage to evacuate as soon as possible. However, in serious situation, the jam of people in a hall or a theater may cause panic and become obstruction to refuge. To prevent this situation, it is necessary to know the behavior of people in a hall. In this paper, a simulation was carried out by introducing Cellular Automata (CA). CA is a class of emergent computation techniques of Complex Systems in which local neighbour rules between each cell emerge the whole phenomena of the system to be considered. In contrast with conventional approaches to the crowd flow simulation, the interaction between each person is represented by the local rule based on the individual behavior of people. Each person constituting a flow of pedestrians in a hall does not do the action that was each decided. It looks at the situation of their circumference and judge where next they should go and act. In other words, each human interaction constitutes the motion in a hall, and the relation that the flow of people in a hall becomes the environment for each human. In this paper, several flow-patterns were simulated, considering the number, the size and the location of exits. And this simulation was performed in consideration of each person's character, speed and the viewing field. This relation is in agreement with the feature of the complexity system. As a result the man flow could be forecasted before the disaster. Finally it is suggested that a hall should be designed considering the flow of people in emergency introducing such a simulation technique as CA.
