From: Mechanical response of dense pedestrian crowds to the crossing of intruders
Crossing of a fairly dense crowd (\(\bar{\rho }\approx 3.5\,{\mathrm{ped}/{\rm{m}}}^{{\rm{2}}}\)) by a cylindrical intruder. (a) Snapshot of an experiment (France), after automatic detection and tracking of the participants’ hats. (b) Trajectories of the intruder (thick red line) and of the participants over a time window of around 5 seconds.
