Game-Theoretic and Inhibition-Based models for crowd motion

Abstract

We propose a new microscopic crowd motion model based on Game-Theoretic principles, from which we derive an Inhibition-Based model for evacuation situations. Each individual is supposed to have a desired velocity that they adapt to the behavior of neighbors that influence them. Possible adapted velocities are defined as instantaneous Nash equilibria: each individual does their best with respect to a personal objective (desired velocity), considering the behavior of the neighbors that influence them (to avoid overlapping). We address theoretical and modeling issues in various situations, in particular when each individual is influenced by all their neighbors, and in the case where the influence relations are structured in a hierarchical way. The second particular case is used to define the Inhibition-Based model.
