Modelling of crowd dynamics considering emergency signs and emotions

Emergency signs play an important role in evacuation guidance, and some works show that the behavior of the crowd in the process of evacuation is easily affected by emotion and personality. However, existing crowd simulation methods rarely involve the interaction between emotion and emergency signs. Thus, a crowd evacuation simulation method considering emotion and emergency signs is proposed to simulate the crowd evacuation behavior under the guidance with signs, and it is verified by simulation experiments through Unity3D. The method provides a novel research perspective for guided crowd evacuation simulation, and it can make simulation results more real to the actual scenes.
