车站内行人动态流动仿真日本名古屋火车站内行人动态流动仿真装置。通过仿真器与真实行人动态流数据的对比，证实了两者之间的差异很小，仿真器能较好地模拟出真实的行人动态流。该仿真器可用于评价车站内行人流量控制方法，从而有助于提高车站内行人服务质量，在紧急情况下制定疏散计划。行人紧急通道动态流动模拟我们构建了一个模拟器，可以自由设置障碍物、疏散指示牌、出口大门、疏散指南。对各种情况下的疏散进行了模拟，确保得出直观合理的疏散流程。我们还在模拟器中安装了烟雾效果，并成功地再现了烟雾中行人的疏散流程。利用仿真器的模型和算法，可以对多层建筑中行人的疏散流程进行模拟，并对疏散方案进行检验。初等元胞自动机的混沌和分形性质证明了Wolfram类I中的初等元胞自动机规则40和规则168具有混沌性质和不同的Lyapunov指数值。从这些结果来看，Wolfram的分类是不充分的，对于复杂的动力现象，在I类中可能存在非常简单的元胞自动机

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
