In recent years, agent-based simulation has become an important tool to study complex systems. However, the models produced are rarely used for decision-making support because stakeholders are o en not involved in the modeling and simulation processes. Indeed, while several tools dedicated to participatory modeling and simulation exist, these are limited to the design of simple KISS models, thus reducing their potential impact. In this article, we present the new participatory tools integrated within the GAMA modeling and simulation platform. These tools, which take advantage of the GAMA platform with respect to the definition of rich KIDS models, allow the modelers to build models graphically and develop distributed serious games easily. Several application examples illustrate their use and potential.

The quantity of data and processes used in modeling projects has been dramatically increasing in recent years due to the progress in computation capability and to the popularity of new approaches such as open data. Modelers face an increasing difficulty in analyzing and modeling complex systems that consist of many heterogeneous entities. Adapting existing models is relevant to avoid dealing with the complexity of writing and studying a new model from scratch. ODD (Overview, Design concepts, Details) protocol has emerged as a solution to document Agent-Based Models (ABMs). It appears to be a convenient solution to address significant problems such as comprehension, replication, and dissemination. However, it lacks a standard that formalizes the use of data in empirical models. This paper tackles this issue by proposing a set of rules that outline the use of empirical data inside an ABM. We call this new protocol ODD+ D (ODD+Decision + Data). ODD+ D integrates a mapping diagram called DAMap (Data to Agent Mapping). This mapping model formalizes how data are processed and mapped to agent-based models. In this paper, we focus on the architecture of ODD+ D, and we illustrate it with a residential mobility model in Marrakesh.

In this work we address the issue of sustainable cities by focusing on one of their very central components: daily mobility. Indeed, if cities can be interpreted as spatial organizations allowing social interactions, the number of daily movements needed to reach this goal is continuously increasing. Therefore, improving urban accessibility merely results in increasing traffic and its negative externalities (congestion, accidents, pollution, noise, etc.), while eventually reducing the quality of life of people in the city. This is why several urban-transport policies are implemented in order to reduce individual mobility impacts while maintaining equitable access to the city. This challenge is however non-trivial and therefore we propose to investigate this issue from the complex systems point of view. The real spatial-temporal urban accessibility of citizens cannot be approximated just by focusing on space and implies taking into account the space-time activity patterns of individuals, in a more dynamic way. Thus, given the importance of local interactions in such a perspective, an agent based approach seems to be a relevant solution. This kind of individual based and “interactionist” approach allows us to explore the possible impact of individual behaviors on the overall dynamics of the city but also the possible impact of global measures on individual behaviors. In this paper, we give an overview of the Miro Project and then focus on the GaMiroD model design from real data analysis to model exploration tuned by transportation-oriented scenarios. Among them, we start with the the impact of a LEZ (Low Emission Zone) in the city center.

La plateforme LittoSIM modélise à partir des données réelles le risque de submersion auquel une île de la côte atlantique française est soumise et propose à quatre équipes de joueurs d’aménager le territoire, en gérant l’urbanisation et les aménagements de défense du littoral, puis de confronter leur gestion du territoire à des épisodes de submersion marine. Le jeu de rôles, épaulé d’un modèle multi-agents, facilite l’appréhension du risque par les élus et les agents communaux et est conçu pour permettre le suivi des actions et leur réorientation dans la plateforme. Cet article soulève la question du réalisme dans une simulation participative : comment a-t-il été mis en œuvre, dans quel but, avec quels effets ? Le dispositif spatial du jeu met tout d’abord en scène une reproduction de la gestion du territoire et joue sur les échelles spatiales et temporelles et sur les échanges interpersonnels. Par ailleurs, la scénarisation, grâce à des leviers incitatifs invitant les joueurs à modifier leurs pratiques professionnelles quotidiennes, produit un décalage et de ce fait une sensibilisation aux enjeux. Enfin, cette démarche participative, dont la dimension réaliste est revendiquée, interroge le chercheur sur sa posture d’accompagnement.

À travers un dispositif de jeu et de simulation mobilisé lors d’ateliers participatifs, cet article étudie les conditions de réception sociale du recul stratégique face à la submersion marine, par des gestionnaires du risque (élus et agents) de Camargue et Normandie. Après avoir défini la notion de réception sociale, l’article décrit le processus de réception via les actions de jeu des participants. La variété des formes de compréhension que les gestionnaires ont du recul stratégique et la dimension temporelle sont mises en avant. D’autres facteurs de réception sont ensuite mis en exergue (contexte politique, représentations sociales, perception des échelles de gestion), à partir cette fois-ci de l’analyse des discours territorialement ancrés qu’ont les participants durant les ateliers. À travers les parallèles opérés entre jeu et réalité, l’étude met en évidence les facteurs qui déterminent la réception sociale des politiques publiques de gestion des risques côtiers sur chaque territoire étudié.
