Centralité et forme urbaine. La dimension morphologique de l’accès à la ville et ses potentialités dans la perspective d’une alternative à la mobilité automobile

Abstract : This thesis focus on the relation between the notion of centrality and urban form, both from a general point of view and for alternatives to automotive mobility in urban areas.Following a chronological order, a first part questions this relation from a theoretical angle by comparing selected works on the notions of center and centrality on the one hand, and on urban forms on the other. Leading to criteria for identifying centers, it also leads to consider centrality as referring to a gradual reality relating to urban space as a whole.Using these criteria and this definition, a second part provides morphological analysis of different spaces within the metropolitan areas of Washington, Paris and Shanghai. Highlighting a determining role of walking, these analysis allow a classification of identified centers according to how their morphological characteristics contribute to condition relations between urban amenities, both inside these places and in relation to their environment. But they also lead to the identification of a reticular expression of centrality, which is not inclined to be characterized by the only notion of center, and appears to be a potentially effective for alternatives to automotive mobility.
