The sketch of the experiment. The exit width is fixed as 0.7 m. The measurement area (2 m × 1 m) is selected to measure the time evolution of density and speed in “Time profiles of density and speed” section. To measure the movement characteristics of pedestrians, the coordinate system takes the lower-left corner as the origin point, the direction parallel to the exit as the X-axis, and the direction perpendicular to the exit as the Y-axis.
