Macroscopic pedestrian flow simulation using Smoothed Particle Hydrodynamics (SPH)
Transportation Research Part C: Emerging Technologies, 2020 Macroscopic pedestrian models are theoretically simpler than microscopic models, and they can potentially be solved faster while producing reasonable predictions of crowd dynamics. Therefore, they can be very useful for applications such as large-scale simulation, real-time state estimation and crowd management. However, the numerical methods presently
