Analyse de la représentation en grille du territoire pour l'étude de l'évolution du chemin de fer

Abstract : Interactions between transportation and territory are an important topic in scientific literature. The economic impact of a new infrastructure remains the most common subject of investigation (Kasraian et al., 2016). We focus here on the role of an existing demographic distribution in the design of transportation networks. The use of transportation network algorithms is a relevant approach in this context. However, these methods require as input a grid-like representation of the territory. They also make implicite hypothesis on mobility. In this paper, we discuss the construction of this grid and the effect of the choices made in order to define it. We first show that a grid based on triangulation achieves a good balance between precision and sparsity. Then we underline that the scale chosen when constructing the grid may have a significant impact on modelling results.
