Pedestrian Dynamics
Pedestrian Dynamics Research
This group aims to analyse and model pedestrian behaviour under various conditions. With the knowledge of pedestrian flow and its interaction to obstacles, public infrastructure may be improved from the view of efficiency as well as security. The research is provided mainly on microscopic approach on small scale systems, e.g. several joined rooms or one train unit, but it focuses on microscopic accuracy, respecting the individual features of each participant.
Our analytic team uses the records of cameras or other detectors to evaluate fundamental quantities as velocity, density and flow. The relations of these variables depend on infrastructure and participant’s preferences, but general phenomena may be observed. Focusing of some specific feature, egress experiments are organized to get dedicated data. The deep analysis of cause of flow decrease may prevent many bottleneck issues.
Our modeling team designs, develops and improves pedestrian motion models based on various principles – from simple macroscopic modes enabling analytic solution over force based models introducing social forces to sophisticated agent based systems. Calibration and verification process is run on our experimental data, which makes the whole team to close cooperation.
