From Crowd Dynamics to Crowd Safety: A Video-Based Analysis
Anders Johansson, Dirk Helbing, Habib Z. Al-Abideen +1
The study of crowd dynamics is interesting because of the various self-organization phenomena resulting from the interactions of many pedestrians, which may improve or obstruct the…
Specification of the social force pedestrian model by evolutionary adjustment to video tracking data
Anders Johansson, Dirk Helbing, Pradyumn Shukla
Based on suitable video recordings of interactive pedestrian motion and improved tracking software, we apply an evolutionary optimization algorithm to determine optimal parameter s…
