“…A series of controlled experiments were conducted to explore the commonality behavior of evacuees in evacuation procedures: exit and route choice behavior, stepping and conflict/collision avoidance behavior of pedestrians in different circumstances, including limited visibility conditions, decision-making behavior of social groups in evacuations, fundamental factors (speed, step, pace, etc.) of different human crowds (male/female, young/elder/child, unidirectional/bidirectional/multi-directional) [119][120][121][122][123][124][125][126][127][128].…”

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.

“…16 It is assumed that crews can obtain passenger distribution information at any time without delay. 44 The movement of crews satisfied the basic SFM, and leader with mass m l should adjust current speed v l ( t ) to the desired speed v l 0 ( t ) in the reaction time τ , also his/her moving direction e l c ( t ) should be changed to the optimal exit. Crews who act as leaders can guide the passengers around them to change to other more suitable paths for evacuation by sound or other signals once they are leaders until passenger evacuation finishes.…”

The emergency scenarios of passenger ships are reproduced unrealistically by evacuation drills due to cost and safety limitations, and model simulation is an effective alternative method. To study the evacuation efficiency of an inclined ship, a deck of a Ro-Ro ship with 1065 passengers was modeled on a simulation platform developed based on a social force model (SFM). A series of inclined scenarios were produced by adding the walking speed attenuation factor to the individual parameters. Furthermore, the influence of crew’s guidance was considered in this model, and the effects on evacuation were also analyzed for the entire deck. The simulation results show that the larger the inclination angle is, the more evacuation time that is needed. When the largest inclination angle was 20°, the evacuation time increased by 32.6%. In addition, the participation of crew’s guidance in all of these scenarios significantly accelerated the evacuation efficiency, and this benefit was achieved by the evaluation of the exit flow and congestion level by crew. However, organizing orderly evacuations as soon as possible when the inclination angle is less than 15° and making maximum efforts to ensure evacuation success are still recommended. The findings provide useful insights into a large group of Ro-Ro passenger vessels under inclined emergency evacuation.

“…Accidents such as the Piper Alpha and Deepwater Horizon tragedies have been stimulating fire and evacuation research on offshore platforms. Once the fire occurs, it is often difficult for evacuees to evacuate from the extremely dangerous environment [1] , and it is evident that most of the casualties occur during evacuation [2] . Therefore, it is important to study how to evacuate effectively and reduce the casualties during the evacuation on offshore platforms.…”
