Geoprospective modelling of a crossborder system. The case of the high speed railway project (LGV PACA) in the French, Italian and Monaco region

Abstract : This research concerns the impact of LGV-PACA project, a high speed railway infrastructure which is going to serve the Provence Alpes-Côte d'Azur Region on the horizon 2020. Using a geoprospective approach, this study focuses on the impacts of this project on the evolution of the French-Italian and Monegasc cross-border territory. The geoprospective approach relies on spatial modeling based on a constrained cellular automata MOLAND system (developed by the Joint Research Centre of the European Commission). The use of MOLAND allowed the modeling/simulation/prediction of transportation and land-use, which facilitated the understanding of possible land-use evolution of spaces surrounding the borders. Three chapters are presented in the thesis. In the first chapter we show a methodological framework on potential and existing interdependence between the territorial system and the transportation subsystem. In the second chapter, we approach the question of modeling and spatial simulation while insisting on the difficulties of parameter settings in dynamic and spatially explicit models, and in particular which are in a constrained cellular automata. In the third and last chapter of this thesis, we present the hidden/not well-known/trappy difficulties of a geoprospective approach. From various geoprospective scenarios, this thesis provides several elements of knowledge about the future of a cross-border space which will host high speed trains. It brings concrete answers to questions related to urban growth and accessibility of territories so far isolated from the large European communication corridors. The results of this research are more than ever of interest because, within the framework of knowledge and decision making support of this territory, it focuses on an aspect ignored in studies undertaken by the project owner RFF (Réseau Ferré de France) so far: the simultaneous consideration of transportation infrastructure and land-use for understanding the dynamic of a territory in becoming. Including also land-use characteristics in geoprospective modeling with cellular automata helps the geographer to ask the right questions. RF recently launched new studies on opportunities of providing PACA Region with a high speed railway infrastructure. By making available the estimation of national impacts of this infrastructure on the cross-border territory, carried out simulations that are useful support in decision-making.
