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…
Comprehensive Review and New Analysis Software for Single-file Pedestrian Experiments
Rudina Subaih, Antoine Tordeux, Mohcine Chraibi
This paper offers a comprehensive examination of single-file experiments within the field of pedestrian dynamics, providing a review from both theoretical and analytical perspectiv…
