“…In the existing studies, the cell size is 0.4 [4] or 0.5 m [18] which is similar to the cell size used in the corridor simulation. In our new model, the cell size is drawn based on the stair structure and human body size.…”

Building evacuation in case of emergencies has long been recognized as a crucial issue, especially for the stair evacuation because evacuees may spend most of the evacuation time in stairs. To predict the evacuation time in stairs, simulations are commonly used, but known simulations ignore the stair structure and the fact that people may change their speeds during evacuation. As a result, how to introduce a reasonable mechanism on how evacuees change their speeds and improve the stair evacuation simulation are important. In this paper, a new Cellular Automata (CA) model where a new grid map is introduced based on the stair structure, and then the interaction among evacuees can be simulated better than the existing CA simulations. To make a reasonable mechanism of changing speed, the social forces will be introduced to the new CA model based on the advantages of social force models. However, social force model is a continuous model and CA model is a discrete model, and there is a gap to use social forces directly into a discrete model. To bridge the gap, the system time interval is shortened, and then evacuees have variable speeds by updating their positions during several intervals. To validate this simulation, an experiment was held in a high-rise building. In the fire drill, harmless smoke was released to make the drill similar to real events. The simulation results are similar to the fire drill data by comparing evacuation time.

Przegląd modeli uwzględniających efekt zarażania emocjonalnego w procesie ewakuacjiABSTRACT Purpose: A number of programs are available on the market to estimate individual parameters of the evacuation process. Starting from the estimated time of evacuation from the building, to the distribution of the use of individual evacuation routes, to the impact of the spreading of fire on evacuees. The most commonly used programs for modeling the evacuation process include Simulex, FDS + Evac, and Vissim. Currently, evacuation modeling software does not take into account psychological interactions between evacuees. What is of special importance in the evacuation process is emotional contagion. The phenomenon of emotional contagion has been the subject of extensive research recently. This article presents the current progress on the development of an accurate model that takes into account the effect of emotional contagion. Problems hindering the development of an appropriate model are also presented. The development prospects for such tools are also discussed using the example of the available models, such as ESCAPE, ASCRIBE and Durupinar. Introduction: The design of modern buildings requires the participants of the investment process to implement a number of solutions to ensure the safety of their future users. All types of modelling tools are used for this purpose, including those for evacuation modelling. Progress in the design of escape routes has contributed to the design of buildings that are much safer than they used to be in the past. Proper building design requires an analysis of a number of fire scenarios. The development of evacuation models is indispensable for proper safety assurance in designed and constructed buildings. Methodology: This article reviews the available literature on the existing models taking into account the effect of emotional contagion. It analyses and compares existing models and discusses limitations that prevent their use for evacuation safety analysis. Conclusions: Current evacuation modelling software does not take into account emotional contagion, an important phenomenon that occurs between evacuees. This phenomenon is common in every-day life but is particularly important during events involving crowds of people. It is necessary to further develop existing models to allow a more accurate reflection of reality, also in the context of emotional contagion. What may be helpful in this respect is research in the field of the psychology of emotion. ; Artykuł udostępniany na licencji CC BY-SA 4.0 (https://creativecommons.org/licenses/by-sa/4.0/).

“…These models often have high efficiency and have been adopted in many commercial softwares. Many researchers work are based on CA models [16][17][18][19]. Schadschneider et al [20] and Nowak et al [21] calibrated the floor field model in single-file and counterflow Supposing that a pedestrian is in cell o and that the exit is in oa direction, he/she will have three moving direction: oa, ob and oc, besides, oa direction is his/her first choice.…”
