When is a bottleneck a bottleneck?
Andreas Schadschneider, Johannes Schmidt, Vladislav Popkov
Bottlenecks, i.e. local reductions of capacity, are one of the most relevant scenarios of traffic systems. The asymmetric simple exclusion process (ASEP) with a defect is a minimal…
A force-based model to reproduce stop-and-go waves in pedestrian dynamics
Mohcine Chraibi, Antoine Tordeux, Andreas Schadschneider
Stop-and-go waves in single-file movement are a phenomenon that is ob- served empirically in pedestrian dynamics. It manifests itself by the co-existence of two phases: moving and…
Jamming transitions in force-based models for pedestrian dynamics
Mohcine Chraibi, Takahiro Ezaki, Antoine Tordeux +3
Force-based models describe pedestrian dynamics in analogy to classical mechanics by a system of second order ordinary differential equations. By investigating the linear stability…
Fibonacci family of dynamical universality classes
Vladislav Popkov, Andreas Schadschneider, Johannes Schmidt +1
Universality is a well-established central concept of equilibrium physics. However, in systems far away from equilibrium a deeper understanding of its underlying principles is stil…
Defect-induced phase transition in the asymmetric simple exclusion process
Johannes Schmidt, Vladislav Popkov, Andreas Schadschneider
We reconsider the long-standing question of the critical defect hopping rate in the one-dimensional totally asymmetric exclusion process (TASEP) with a slow bond (defect). Fo…
