From: Mechanical response of dense pedestrian crowds to the crossing of intruders
Pedestrian densities (in ped/m2) in the frame of the moving cylindrical intruder, in moderately dense (left, \(\bar{\rho }\approx 2.5\) ped/m²), fairly dense (middle, \(\bar{\rho }\approx 3.5\) ped/m²), and very dense (right, \(\bar{\rho }\approx 6\) ped/m²) crowds. The participants were either facing the intruder (France, top row) or randomly oriented (France, bottom row). Panel (a) is an average over 7 crossings, which we abbreviate into ‘x7’; (b) x9; (c) x7; (d) x5; (e) x9; (f) x5.
