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…
Generalized collision-free velocity model for pedestrian dynamics
Qiancheng Xu, Mohcine Chraibi, Antoine Tordeux +1
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…
