Behavioral crowds: Modeling and Monte Carlo simulations toward validation

A mesoscopic model of behavioral crowds is developed within the framework of the kinetic theory for active particles. An analytic long-time equilibrium solution is obtained which gives a fundamental density-velocity diagram consistent with the empirical evidence. Numerical simulations based on a Monte Carlo particle method show that the proposed model has the capability to qualitatively depict emerging behaviors and to provide a realistic description of the crowd dynamics in complex evacuation scenarios.
