“…Crowd behaviors including clogging, pushing, and trampling could lead to serious fatalities in the evacuation process. The crowd behavior models could be divided into the cellular automata model [30][31][32][33][34][35][36], social force model [37][38][39][40][41][42][43], lattice gas model [44][45][46][47][48][49][50][51], game-theoretic model [52][53][54], animal agent-based model [55][56][57][58][59][60][61][62], and computer agent-based model [63][64][65][66][67][68][69][70][71][72]. The functions of evacuation models have been analyzed and are shown in Table 2.…”

Fire safety evacuation has been used in numerous different kinds of buildings. This research conducts a scientometric review of fire safety evacuation applications and advances in the buildings to clarify the research trends of fire evacuation in the future and provide guidance for relevant research. A total of 3312 journals and conference proceedings were analyzed through different dimensions. The result proves that evacuation environments concentrate mainly on residential building, commercial building, school, and railway station. The characteristics of the evacuee have been gradually refined in recent years, including children, the elderly, patients, and vulnerable groups. The main experimental approaches of fire safety evacuation are evacuation drills, site records, and VR/AR experiments. The crowd behavior models mainly consist of six types: a cellular automata model, a social force model, a lattice gas model, a game-theoretic model, an animal agent-based model, and a computer agent-based model. The analysis results in the theoretical method are becoming gradually closer to the behavioral characteristics and movement data of the crowd during the actual evacuation with improvements of practical considerations. The study of evacuation drills, disaster rescue, emergencies, and other external environmental factors will become the forefront of future research, and subway stations, airports, high-rise building, and other personnel places will be the focus of the study of crowd evacuation.

“…Microscopic method is one of the best choices for modeling and examining crowd behavior as the behavior and mobility of the entire population of the area would be affected by the behavior of each agent. Cellular automata (CA), 20 lattice gas, 21 social force, 22 and game theory- 23 based evacuation simulation models are illustrations of microscopic models that are computationally efficient and able to support large parameter spaces for simulation. The general drawbacks are that models are not fully realistic because these models are in discrete space and most of them simulate the crowd movement via probability theory.…”

The role of crowd behavior and cooperation strategies during evacuation

Crowd dynamics have constituted a hotspot of research in recent times, particularly in areas where developmental progress has taken place in crowd evacuation for ensuring human safety. In high-density crowd events which happen frequently, panic or an emergency can lead to an increase in congestion which may cause disastrous incidents. Crowd control planning via simulation of people’s movement and behavior can promote safe departures from a space, despite threatening circumstances. Up until now, the evolution of distinctive types of crowd behavior towards cooperative flow remains unexplored. Hence, in this paper, we investigate the impact of potential crowd behavior, namely best-response, risk-seeking, risk-averse, and risk-neutral agents in achieving cooperation during evacuation and its connection with evacuation time using a game-theoretic evacuation simulation model. We analyze the crowd evacuation of a rectangular room with either a single-door or multiple exits in a continuous space. Simulation results show that mutual cooperation during evacuation can be realized when the agents’ population is dominated by risk-averse agents. The results also demonstrate that the risk-seeking agents tend toward aggressiveness by opting for a defector strategy regardless of the local crowd densities, while other crowd behavior shows cooperation under high local crowd density.

“…Simulations on crowds have gained tremendous attentions in recent years. There exist some models that are widely used to describe pedestrian behavior, for example, rule-based flocking systems [11], social forces model [12], lattice gas model [13], [14], cellular automaton model [15], and floor field model [16]. Physical property is an important factor that can not be ignored in crowd simulation.…”

Simulation on crowd evacuation has attracted plenty of attention in the past few years. Emotion plays a significant role in human decision making processes and on the behaviors during the evacuation. Moreover, grouping is a common phenomenon in crowds, and there are a lot of roles included in a group. In this paper, we present a unified framework to model the structure aspect of the groups with emotion for a crowd suffering fires and explosions in public areas. The proposed evacuation framework consists of two components: (1) an emotion model for various roles in the case of an emergency. Emotional changing is a complex process where different roles are influenced by different factors. (2) Both intra-group structure and inter-group relationship are considered to simulate the herd phenomenon in emergency. The structure and behaviors of a group are related to the emotions of different roles. A follower can decide whether to leave the group or not according to the emotion of the group leader and the one of his own, thus the members of the group may always dynamically change. Simulation results show that the developed framework can practically model the emotion changing and different group structures of evacuation crowds.
