The ESPACE laboratory of the CNRS and Avignon University is involved in the POIESIS project – Pour une Objectivation Innovante et une Évaluation Systémique des Services Express Régionaux Métropolitains (For an Innovative Objectification and a Systemic Evaluation of Metropolitan Regional Express Transport Services), led by SNCF. The project aims to develop a methodology and tools for anticipation, spatial optimization, and support of SERMs (Metropolitan Regional Express Services) in French regions. This project is based on an individual-centered spatial analysis approach (geomatics) using AgentBased Modeling to model mobility and its evolution. The postdoctoral researcher will intervene in the second phase of the project, during the generalization of the territorial diagnostic tool and the exploration of scenarios in different geographical contexts.

Mission

The recruited researcher will provide a comparison of several major types of mobility modeling, with the aim of improving their respective efficiency and usage: four-step models, multi-agent systems and a mobility model developed in the PhD thesis of Louisette Garcin. This comparison will be carried out from theoretical (emergence, economics, gravity, spatial interactions, graphs, urban form), methodological (robustness, error propagation, discrete choice, rationality), and operational (forecasting capacity, decision support, agility

Planned activities

• Literature review on four-step models and multi-agent systems in land passenger transport

• Application of mobility models from the different approaches on two study sites

• Comprehending of the Louisette Garcin’s mobility model

• Definition of key indicators for comparison

• Sensitivity analysis of methods and indicators, including uncertainty assessment

• Development of automated scripts (model execution and comparison)

• Production and recommendation of a global methodology for comparing spatial modeling of SERMs at the metropolitan scale

• Integration of AI-based learning capabilities to refine all types of models studied

• Consideration of environmental aspects in the comparative evaluation (positive impact and modal switch from personal cars)

• Publication of two cosigned papers with the team in international peer-reviewed journals

• Participation in three conferences in the field to disseminate the results
