| Abstract: | The crowd evacuation of pairs of pedestrians (i.e. pairs consisting of a parent and a child) is numerically investigated. Here, it is assumed that all pedestrians have their own partners, and move randomly inside the bounded domain of the right-hand room as an initial state. All pedestrians start their evacuations after they contact their partners. The evacuations are completed by the transfer of all the pairs from the right-hand room to the left-hand room through an exit. A frozen swarm tends to appear in the right-hand room as the total number of pedestrians increases. The frozen swarm moves without changing its form, unless it is dissolved by a strong collision with a pair of pedestrians that comes back from the left-hand room by accident. Finally, the evacuation speed also depends on the area of the Escape Zone, whereas an obstacle placed in front of an exit also changes the speed of the evacuation in accordance with the type of motion of the children. |
