In this paper, we investigate the calibration of a mathematical model describing different behaviors occurring during a natural, a societal, or a technological catastrophe. This model was developed in collaboration with geographers and psychologists. To collect information on the level of stress, psychologists of the LPPL laboratory of Nantes...

Abstract One of the major current challenges in the field of security and safety of populations is to advance further in the understanding and the ability to anticipate their behaviors when faced with threats or disasters. Several factors such as the hazard properties or the culture of risk can influence people behavior during a disaster. In...

The human society is increasingly impacted by many natural, technological and societal disasters that stress the vulnerability of populations. In addition, the crisis management is particularly observed by people who judge their performance. To maintain their credibility, the authorities must prove their control over the situation. Significant...

Faced with an ongoing or imminent danger, crisis managers must do their utmost to protect the exposed population and limit the extent of the disaster. More than during the pre- and post-disaster phases, time is of the essence. This temporal specificity of the disaster is essential compared to the risk. It requires a perfect coordination and a...

This chapter proposes to generalize to a geographical context an innovative SIR-based model describing human collective behaviors in situations of disasters. The novelty of this work is to adopt a complex network approach in order to model the influence of the space on the transitions among one behavior and the others. This network model will...

In a world more and more affected by natural and/or industrial disasters, it is essential to understand, analyze and control human behavior during such events. The work presented in this article is one of the results of a transdisciplinary collaboration between geographers, psychologists, mathematicians, computer scientists, operational staff...

La recherche Com2SiCa dans laquelle s'inscrit cet article vise les objectifs suivants : d'une part appréhender la diversité des comportements humains et des possibles changements d'états pouvant se produire lors d'une catastrophe majeure, soudaine, rapide, avec peu ou sans signe précurseur ; d'autre part analyser les trajectoires de déplacement...
