From: Characteristic time in highly motivated movements of children and adults through bottlenecks

Velocity profiles during the congested state for highly motivated students’ bottleneck experiment (b = 1.05 m)8. Color for the speed value, white arrows for the speed directions, and grey lines for speed contours. Note that the bottleneck length (1.9 m) is omitted to better compare with the velocity map of children’s experiments, as we focus on the velocity inside the artificial room.
