“…Following this approach, the use of FD as a way to study the capacity of collective systems was widely adopted and it started to be used in pedestrian dynamics. Nowadays, the FD is one of the most important macroscopic observables used in this field [6][7][8][9][10][11] allowing to establish comparisons between different experiments and validating numerical models. Furthermore, the FD has been applied in different scenarios and geometries, such as waiting rooms, stairs, sidewalks, or corridors with uni and bidirectional pedestrian flow [12].…”

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) global density, (ii) prescribed walking speed, and (iii) suggested safety distance. Then, by means of the Voronoi diagram we are able to compute the local density associated to each pedestrian, which is afterward correlated with its corresponding velocity at each time. In this way, we discover a strong dependence of the speed–density relation on the experimental conditions, especially with the (prescribed) free speed. We also observe that when pedestrians walk slowly, the speed–density relation depends on the global macroscopic density of the system, and not only on the local one. Finally, we demonstrate that for the same experiment, each pedestrian follows a distinct behavior, thus giving rise to multiple speed–density curves.
