“…Apart from the issues mentioned above, evacuation speed and counterflow studies were also given much attention [13,14]. A study where the actual experiment was conducted with pedestrian counter flow was presented by Isobe et al [15], who clarified the characteristic properties of pedestrian channel flow and showed the simulation model representing the counter flow. Cłapa et al [16,17] showed that the people density confirmed the dependency between the flow density of evacuating people and the speed of moving people.…”

To untangle the arching effect of a crowd as much as possible in emergency evacuations, we employ a theoretical model of equilibrium partition of crowd batch. Based on the shortest time arrangement of evacuation, the crowd is divided into appropriate batches according to the occupied time of evacuation channel in order to determine the occupant number of every evacuation passageway. The number of each batch crowd is calculated under the condition that the time of entering the evacuation passageway is equal to the time of crossing over the evacuation passageway. Subsequently, the shortest processing time (SPT) rule establishes the evacuation order of each batch. Taking a canteen of China Three Gorges University as a background, we obtain the waiting time from the first person to the last one entering the evacuation channel in every batch by simulation. This research utilizes data from simulations to observe an untangling process against the arching effect based on the SPT rule. More specifically, evacuation time only lasts for 180.1 s in order and is 1.6 s longer than that in disorder, but the arching effect disappears. Policy recommendations are offered to improve the evacuation scheme in disaster operations.

“…In order to investigate the essence of pedestrian flow in a controllable way, some pedestrian flow experiments were conducted in recent years (Daamen & Hoogendoorn, 2003;Isobe et al, 2004;Helbing et al, 2005;Kretz et al, 2006;Moussaid et al, 2009;Zhang et al, 2011Zhang et al, , 2012Li & Dong, 2012;Lian et al, 2015). Many of them are recorded by cameras, and the video data can be good resource for the study of pedestrians' behaviors.…”

“…On the one hand details of pedestrian evacuation have been cast into mathematical formulations yielding various representations of pedestrian interactions [7][8][9][10][11][12][13]. On the other hand theoretical developments have been conducted to model emergency evacuation and situations [14][15][16][17][18][19][20][21][22][23][24][25][26][27] using sophisticated simulation methodologies.…”

This paper considers a method for the definition of pedestrian escape routes by means of the simulation of pedestrian outflow. Feasible solutions are generated and compared in terms of evacuation time. In the proposed method an aggregate model for the estimation of evacuation time of a building is adopted. Such a method can be easily implemented and can be used to give a first evaluation of evacuation procedures without performing evacuation drills and can be used to give a fast response in identifying critical points on the network. To check the capabilities of the models used within the proposed approach, results obtained from simulations are compared with data recorded from an experiment on a test site conducted in a primary school located in an Italian town; an application consisting of designing escape routes for a school is also presented.
