“…Moreover, the peak density locates in the middle of the exit, which is closer to the bottleneck entrance compared to the previous study 4 . Focusing on the high motivated adults in the 1.05 m width bottleneck experiment in 8 , the density in the front of the exit region is arch-like distribution and the peak density reaches 6 ped/m 2 and locates 0.5 m away from the exit entrance. However, compared to the low motivated adults 4,11 , both in 1.0 m width and 1.1 m width bottleneck experiment (bottleneck length is 4.0 m), the distribution of density is teardrop-shaped like and the peak density locates 1.0 m away in front of the bottleneck entrance.…”

“…Bottleneck as a common geometry in many pedestrian infrastructures often restricts the pedestrian flow 4-10 and the arch-like distribution of pedestrians around an exit are observed both in adults and children groups when they are in a rush 4,8,10 . It is reported that the peak density region locates in the front of the bottleneck and the distance to the entrance is related to the type of pedestrians (running pre-school children: 0.3 m, walking adults: 1.0 m) 4, 11 .…”

“…Walking speeds of pre-school children are smaller than that of pupils 12 and adults 13 , while preschool children tend to run 12 and they move faster than adults at the same density 14 in evacuation drills. Focusing on the movement of adults, the higher the speed is, the more likely the movement direction pointing to the exit is based on the previous empirical study 8 . Considering previous velocity characteristics, both pedestrian type (adults or children) and movement motivation (walking or running) show an impact on the velocity of pedestrians.…”

Current codes for fire protection of buildings are mainly based on the movement of adults and neglect the movement characteristic of pre-school children. Having a profound comprehension of the difference between children and adults passing bottlenecks is of great help to improve the safety levels of preschool children. This paper presents an experimental study on the bottleneck flow of pre-school children in a room. The movement characteristics of children’s and adults’ bottleneck flow are investigated with two macroscopic properties: density and speed profiles as well as microscopic characteristic time: motion activation time, relaxation time, exit travel time and headway time. Arch-like density distributions are observed both for highly motivated children and adults, while the distance between the peak density region and the exit location is shorter for children and longer for adults. Children’s movement is less flexible manifested as longer motion activation time and longer relaxation time compared to that of adults. The findings from this study could enhance the understanding of crowd dynamics among the children population and provide supports for the scientific building design for children’s facilities.

“…Moreover, as people tend to gather around the exit and form high-density regions in previous bottleneck experiments 4,8,12,23 , to quantify the magnitude of clogging events, time headway, the time interval of two consecutive pedestrians passing through exits, are investigated. Previous studies propose that higher competition leads to longer time headway both for children and for adults 4,24 .…”

This paper presents an experimental study on the bottleneck flow of pre-school children in a room. The movement characteristics of children’s and adults’ bottleneck flow are investigated with two macroscopic properties: density and speed profiles as well as microscopic characteristic time: motion activation time, relaxation time, exit travel time and time gap. Arch-like density distributions are observed both for highly motivated children and adults, while the distance between the peak density region and the exit location is shorter for children and longer for adults. Children’s movement is less flexible manifested as longer motion activation time and longer relaxation time compared to that of adults.
