Crowd Simulation Model Integrating "Physiology-Psychology-Physics" Factors

Crowd simulation is a daunting task due to the lack of a comprehensive analysis of crowd movement. In this paper, we present a novel unified model for crowd simulation involving human physiological, psychological, and physical factors. We reveal the inherent relationship between these factors ignored by previous methods: in terms of physiology, we present a method for the computation of human physical strength based on doing work in physics; in terms of psychology, inspired by the James-Lange theory in biological psychology, the relationship between physical strength and emotion is delineated and the traditional SIR (SusceptibleInfectious-Recovered) model is improved; in terms of physics, we propose a method combing the physical strength and emotion together to determine individual movement, considering the fact that physical strength and human emotion always work together to affect individual movement. Physiological, psychological, and physical factors are integrated into the comprehensive model, and the relationship among every part is determined. The proposed model has been verified by simulation experiments. The simulation results show that the proposed method can simulate group behavior that conforms to real-world scenarios. It can reliably predict the physical strength and emotion of a crowd in an emergency.
