This paper describes a modeling of pedestrians flow in a concouse of the station using Cellular Automata (CA). CA was developed by John von Neuman and Stanislaw Ulam in 1940s, and considered as a class of computer modeling techniques of Complex Systems, in which the local neighbor interactions of components of the system emerge the whole phenomenon. Introducing the local interactions of pedestrians one another and between a pedestrian and equipment of the station, the positions of pedestrians to proceed at the next time step were estimated and flow simulation was conducted. The simulator was composed of a Map Editor, a simulator, and data definition files produced in relation to the Map Editor. A design engineer can draw a map of concourse by Map Editor on a personal computer, and conduct a simulation under various boundary conditions. The results may be used for not only a prediction of the total amount of pedestrians through a concouse but also considering a counterplan for unexpected trouble of traffic planning or disasters.
