When legs and bodies synchronize: Two-level collective dynamics in dense crowds

Thomas Chatagnon, Mohcine Chraibi, Julien Pettré +2

Ultra-dense crowds, in which physical contact between people cannot be avoided, pose major safety concerns. Nevertheless, the underlying dynamics driving their collective behaviour…

Modelling vehicle and pedestrian collective dynamics: Challenges and advances

Antoine Tordeux, Cécile Appert-Rolland, Alexandre Nicolas +2

In our urbanised societies, the management and regulation of traffic and pedestrian flows is of considerable interest for public safety, economic development, and the conservation…

Noise-induced transition to stop-and-go waves in single-file traffic rationalized by an analogy with Kapitza's inverted pendulum

Oscar Dufour, Jakob Cordes, Alexandre Nicolas +3

Stop-and-go waves in vehicular traffic are commonly explained as a linear collective instability induced by e.g. response delays. We explore an alternative mechanism that more fait…

Modelling car-following dynamics with stochastic input-state-output port-Hamiltonian systems

Julia Ackermann, Matthias Ehrhardt, Thomas Kruse +1

In this contribution, we introduce a general class of car-following models with an input-state-output port-Hamiltonian structure. We derive stability conditions and long-term behav…
