Formes urbaines, mobilité et ségrégation. Une comparaison Lille, Lyon et Marseille (France)

Urban forms, mobility and segregation. A Lille, Lyon, Marseille (France) comparison. - This paper presents the main results of a research program that looked at the impact of specific polycentric urban forms on commuting patterns and intra-urban segregation. Our results point out three different models. Lyon presents a took-over monocentrism, with visibly and diffuse inequalities. Marseille is characterized by a consuming duocentrism and socially doubly unequal. In Lille we highlight a thrifty polycentrism, but socially excluding. Further research works will test the relevance of these models on other European cities with one million inhabitants.
