In this work, using the theory of first-order macroscopic crowd models, we introduce a compartmental advection-diffusion type model, describing the spatio-temporal dynamics of a population in different human behaviors (alert, panic and control behaviors) during a catastrophic event. For this model, we prove the local existence, uniqueness and regularity of a solution, as well as the positivity and boundedness of this solution that allows the global existence. Then, in order to study the spatio-temporal behavioral dynamics of a population during a disaster event, we present several numerical simulations for different scenarios of evacuation.

“…Silgado-Correa et al [53] proposed a mathematical model for predicting accidental gas dispersion and the proposed ). Moreover, the cellular automaton (CA)-based model used in this study can also be replaced by more advanced evacuation models with the consideration of more pedestrian behaviors and emergency communications, such as multiagent-based modeling [35] and social force models [37].…”

“…Firstly, Social Force models are capable of simulating stepping over, crawling and climbing over motions. For example, a study (Liu et al, 2022) developed a Social Force model to simulate the evacuation in a complex environment based on observed data. Pushing-away and stepping-over behaviours occurring in the interaction between pedestrians and movable objects were modelled (e.g., chairs, boxes placed on the ground).…”

Abstract. Pedestrian motions and behaviours in evacuations are compactly interrelated indoor environments. According to how pedestrians interact with indoor environments in three-dimensional (3D) space, 3D indoor-pedestrian interaction is defined as five sorts of specific pedestrian motions, i.e., stepping over, crawling, bent-over walking, jumping over and climbing over. However, the occurrence and prevalence of the interaction in actual evacuations have not been identified, and the degree of effectiveness and practicality of the evacuation simulation models regarding the interaction is yet to be evaluated. Understanding the interaction and simulating it realistically bring apparent benefits to support informed policymaking, building safety optimization and emergency relief efforts. Therefore, this article aims to review the 3D indoor-pedestrian interaction in actual evacuations, assess the capabilities and performance of the evacuation simulation models for the interaction, and identify their limitations and challenges for future work. We first demonstrate that the fundamental relationships between the decision-making process of a pedestrian, object distance and object size/shape in 3D space are unclear yet, and the scarcity of experimental investigation for local routes choices and each motion is vast. Subsequently, the comparisons between Social Force models, Cellular Automata models and Agent-based models suggest that these microscopic models can yield the 3D indoor-pedestrian interaction, but the height dimension of 3D space is not explicitly considered during the evacuation modelling. This article is expected to advance the understanding of pedestrian evacuations in 3D space, ultimately improving pedestrian safety in indoor environments.
