Since Cellular Automata (CA) have been proposed by von Neumann in the late 1940s, CA have been applied in a variety of scientific researches on complex system, including traffic models and biological fields. It is an idealization of a physical system in which space and time are all discrete. In this study, we have simulated evacuation dynamics by Real-coded Cellular Automata (RCA), which we proposed as a new approach for pedestrian flow. The evacuee's motion is determined by the floor field model in case of the evacuation from a large room with one exit. Examples of the floor field are shown in Fig. 2. Two cases are considered; with and without an obstacle in the room. To compare results in both cases, we discuss the evacuation route and the total evacuation time. In addition, the traffic flow of cars in a parking area is simulated.
