Effect of physical distancing on the speed–density relation in pedestrian dynamics

Mostrar todas las versiones(2)

"We report experimental results of the speed-density relation emerging in pedestrian dynamics when individuals keep a prescribed safety distance among them. To this end, we characterize the movement of a group of people roaming inside an enclosure varying different experimental parameters: (i)...
