Impensée mais structurante, refoulée mais exhibée : la mobilité urbaine des marchandises

Abstract : Still widely unexplored thirty years ago, urban freight transport is now undergoing an indisputable scientific development under the tutelage of national and international institutions. This subject now emerges as a substantial issue since consumers’ behaviours and supply chain management evolutions strongly impact cities’ sustainability. However, it seems that urban planners hardly take this new topic into account on a local level. Although it is an essential function of the urban system, freight transport remains widely unregarded by public decision makers, when it is not considered as a negative consequence of urban activity.This thesis focuses on the integration of a subject envisioned as poorly structuring for urban planners, studied here at the local authorities’ level. In the 1990s the necessity emerged for urban freight transport to be conceptualised in a way that differed from interurban freight transport. We now also consider that this subject needs to be specifically adapted to suit urban planners’ issues and we discuss the conceptual bases necessary to shift from a technical and statistical approach of transport to a view of urban freight mobility encompassing the dynamics of the “urban freight” system. Relying on the examples of nine French conurbations, we then confront urban planning policies to the specificities of urban freight mobility and describe the resulting conflicts and inconsistencies. We then develop the case of Lyons to illustrate the complex territorial dynamics and interactions underlying urban freight mobility and provide an analysis of how the actors’ awareness of this topic has evolved and to what extent it can be raised. Finally, in order to study the effects the (in)actions of city planners on urban environment we detail the process of integration of freight mobility through two urban development operations in Lyons, the “Lyon Confluence” project and the Garibaldi street project.Despite the existence of measuring and action tools, we show that urban freight mobility is still an illegitimate subject, at odds with mainstream urban planning. In this context, freight specialists in local authorities are largely kept away from the planning process, but are exposed and used as an alibi to demonstrate the capacity of public authorities to work on a complex subject.
