Simulation of Dynamic Flow of Pedestrain in a Railway StationA simulator for the dynamical flow of pedestrain in a railway station which is really exists in Nagoya, Japan. Comparing the real data and the data form the simulator for the dynamic flow of pedestrain, it has been confirmend that the difference between them is small and then the simulator can mostly emerge the real dynamic pedestrain flow.The simulator may be used for evaluating the methods controlling the flow of pedestrain in the station and then contribute to improving the quality of services for the pedestrain in the station and making evacuation plan in an emergency arises.Simulation of Dynamic Flow of Pedestrain Man Emergency AriseWe have constructed a simulator in which you can freely install obstacles, evacuaton sign bords, exits gates, evacuation guides. Evacuation simulations have been performed in a various kinds of situation, and we make it sure that intuitively reasonable evacuation flows are emerged. We have also installed effects of smoke into the simulator and successfully restage the evacuation flow of pedestrian in smoke.Using the model and algorithm of the simulator, it is possible to restage evacuation flow of pedestrian in multistoried buildings and examine evacuation plans.Chaos and Fractal Properties fo Elementary Cellular AutomataIt has been shown that the elementary cellular automata rule 40 and 168 in Wolfram class I have chaotic properties and a diverse values of Lyapunov exponent. From these results, Wolfram's classification is suggested to be insufficinet and there are possibly very simple cellular automata in the class I for complex dynamical phenomena
