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…
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 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…
Stability of heterogeneous linear and nonlinear car-following models
Matthias Ehrhardt, Antoine Tordeux
Stop-and-go waves in road traffic are complex collective phenomena with significant implications for traffic engineering, safety and the environment. Despite decades of research, u…
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…
Single-file pedestrian dynamics: a review of agent-following models
Jakob Cordes, Mohcine Chraibi, Antoine Tordeux +1
Single-file dynamics has been studied intensively, both experimentally and theoretically. It shows interesting collective effects, such as stop-and-go waves, which are validation c…
Social distancing and the future of pedestrian dynamics
Mohcine Chraibi, Andreas Schadschneider, Antoine Tordeux
Many countries have introduced social distancing rules during the COVID-19 pandemic in order to reduce spreading of the virus in public spaces. This has inspired research on pedest…
Time-continuous microscopic pedestrian models: an overview
Raphael Korbmacher, Alexandre Nicolas, Antoine Tordeux +1
We give an overview of time-continuous pedestrian models with a focus on data-driven modelling. Starting from pioneer, reactive force-based models we move forward to modern, active…
Predicting pedestrian trajectories at different densities: A multi-criteria empirical analysis
Raphael Korbmacher, Huu-Tu Dang, Antoine Tordeux
Predicting human trajectories is a challenging task due to the complexity of pedestrian behavior, which is influenced by external factors such as the scene's topology and interacti…
Multi-scale description of pedestrian collective dynamics with port-Hamiltonian systems
Antoine Tordeux, Claudia Totzeck
Port-Hamiltonian systems (PHS) theory is a recent but already well-established modelling approach for non-linear physical systems. Some studies have shown lately that PHS framework…
Spontaneous wave formation in stochastic self-driven particle systems
Martin Friesen, Hanno Gottschalk, Barbara Rüdiger +1
Waves and oscillations are commonly observed in the dynamics of self-driven agents such as pedestrians or vehicles. Interestingly, many factors may perturb the stability of space h…
Stop-and-go waves induced by correlated noise in pedestrian models without inertia
Antoine Tordeux, Andreas Schadschneider, Sylvain Lassarre
Stop-and-go waves are commonly observed in traffic and pedestrian flows. In most traffic models they occur through a phase transition after fine tuning of parameters when the model…
The trouble with 2nd order models or how to generate stop-and-go traffic in a 1st order model
Jakob Cordes, Andreas Schadschneider, Antoine Tordeux
Classical second order models of pedestrian dynamics, like the social-force model, suffer from various unrealistic behaviors in the dynamics, e.g. backward motion, oscillations and…
Robustness analysis of car-following models for full speed range ACC systems
Antoine Tordeux, Jean-Patrick Lebacque, Sylvain Lassarre
Adaptive cruise control systems are fundamental components of the automation of the driving. At upper control level, ACC systems are based on car-following models determining the a…

The collision-free velocity model is a microscopic pedestrian model, which despite its simplicity, reproduces fairly well several self-organization phenomena in pedestrian dynamics…
Automated Quality Assessment of Space-Continuous Models for Pedestrian Dynamics
Valentina Kurtc, Mohcine Chraibi, Antoine Tordeux
In this work we propose a methodology for assessment of pedestrian models continuous in space. With respect to the Kolmogorov-Smirnov distance between two data clouds, representing…
Investigation of Voronoi diagram based Direction Choices Using Uni- and Bi-directional Trajectory Data
Yao Xiao, Mohcine Chraibi, Yunchao Qu +2
In a crowd, individuals make different motion choices such as "moving to destination", "following another pedestrian", and "making a detour". For the sake of convenience, the three…
Noise-induced Stop-and-Go Dynamics
Antoine Tordeux, Andreas Schadschneider, Sylvain Lassarre
Stop-and-go waves are commonly observed in traffic and pedestrian flows. In traffic theory they are described by phase transitions of metastable models. The self-organization pheno…
Prediction of Pedestrian Speed with Artificial Neural Networks
Antoine Tordeux, Mohcine Chraibi, Armin Seyfried +1
Pedestrian behaviours tend to depend on the type of facility. Therefore accurate predictions of pedestrians movements in complex geometries (including corridor, bottleneck or inter…
