GesCoCrise, un jeu de rôle pour apprendre à gérer la crise en collectif: Cas de la fermeture du tunnel du Chambon.

This role play allows students and / or managers, engineers or risk prevention specialists to understand the collective management of a crisis linked to a natural risk, involving heterogeneous actors. More exactly, by playing an actor involved in the situation, it makes it possible to represent the needs and expectations of the other, even misunderstandings. The management of communication and information between experts and lay people (victims of the situation) appears essential as a means of collectively managing the situation. This role play allows to training the future preventers in risk governance and resilience in case of natural disasters that may generate other risks (domino effect, cascading) such as economic risks, on transport or social infrastructure.
