Modeling crowd dynamics from a complex system viewpoint

N Bellomo, B Piccoli, A Tosin - Mathematical models and methods …, 2012 - World Scientific
This paper aims at indicating research perspectives on the mathematical modeling of crowd
dynamics, pointing on the one hand to insights into the complexity features of pedestrian …

Time-evolving measures and macroscopic modeling of pedestrian flow

B Piccoli, A Tosin - Archive for Rational Mechanics and Analysis, 2011 - Springer
This paper introduces a new model of pedestrian flow, formulated within a measure-
theoretic framework. It consists of a macroscopic representation of the system via a family of …

Pedestrian flows in bounded domains with obstacles

B Piccoli, A Tosin - Continuum Mechanics and Thermodynamics, 2009 - Springer
In this paper, we systematically apply the mathematical structures by time-evolving
measures developed in a previous work to the macroscopic modeling of pedestrian flows …

A discrete contact model for crowd motion

B Maury, J Venel - ESAIM: Mathematical Modelling and Numerical …, 2011 - cambridge.org
The aim of this paper is to develop a crowd motion model designed to handle highly packed
situations. The model we propose rests on two principles: we first define a spontaneous …

Transport equation with nonlocal velocity in Wasserstein spaces: convergence of numerical schemes

B Piccoli, F Rossi - Acta applicandae mathematicae, 2013 - Springer
Motivated by pedestrian modelling, we study evolution of measures in the Wasserstein
space. In particular, we consider the Cauchy problem for a transport equation, where the …

On the discretization of truncated integro-differential sweeping process and optimal control

A Bouach, T Haddad, L Thibault - Journal of Optimization Theory and …, 2022 - Springer
We consider the Volterra integro-differential equation with a time-dependent prox-regular
constraint that changes in an absolutely continuous way in time (a Volterra absolutely …

A mathematical framework for a crowd motion model

B Maury, J Venel - Comptes Rendus Mathematique, 2008 - Elsevier
In a previous paper, we proposed a model for crowd motion, together with a numerical
algorithm, especially designed to handle highly packed situations. This model rests on two …

Collision-free speed model for pedestrian dynamics

A Tordeux, M Chraibi, A Seyfried - Traffic and Granular Flow'15, 2016 - Springer
We propose in this paper a minimal speed-based pedestrian model for which particle
dynamics are intrinsically collision-free. The speed model is an optimal velocity function …

An overview of the modeling of crowd dynamics

E Cristiani, B Piccoli, A Tosin, E Cristiani… - Multiscale modeling of …, 2014 - Springer
In this chapter we review some of the most important models at microscopic, macroscopic,
and mesoscopic scale, which, in our opinion, represent milestones in their respective fields …

Well-posedness of history/state-dependent implicit sweeping processes

S Zeng, E Vilches - Journal of Optimization Theory and Applications, 2020 - Springer
This paper is devoted to the study of a new class of implicit state-dependent sweeping
processes with history-dependent operators. Based on the methods of convex analysis, we …
