Density profiles during the congested stage in this study. Top row: r1, r2, r3, r4; middle row: r5, r6, r7, r8; bottom row: r9, r10, r11, r12. Color for the density value and white lines for density contours. Noted that in r9, the high-density region locates far from the exit, which is different from other experimental runs. Based on the experimental videos, the phenomenon is due to several children start playing in the region and fail to pass the exit quickly in this experimental run.
