Validation of evacuation dynamics in bottleneck with various exit angles

As society and culture develop more and more, confined spaces which contain dense people are increasing rapidly. There are many cases about crushed to deaths. Several researches have studied pedestrian flow but experimental data are not enough. This paper focuses on comparison between experiment and simulation. Simulation is based on discrete element method with psychological effect and the experiment was conducted using mice with electric stimulus device. Agents of experiment are mice instead of human because of possibility of real casualties. Averaged velocity and total escape time are observed and results of simulation and experiment are qualitatively similar in practice. (C) 2014 The Authors Published by Elsevier B.V.
