Probabilistic dynamics of small groups in crowd flows

Pedestrians in crowds frequently move as part of small groups, which can constitute up to 70% of individuals in public spaces. Dyads (groups of two) are most frequent. Understanding quantitatively the dynamics of dyads walking in crowds is therefore an essential building block to...

Undesired body orientations in competitive pedestrian evacuations

We report time-resolved experimental measurements of human body orientation in extremely dense crowds during highly competitive evacuations. By comparing different scenarios, we find that as competitiveness increases and contact forces among pedestrians build up, orientational or...
