Formes urbaines et durabilité du système de transports. Une application par les coûts de la mobilité urbaine des ménages au sein de l'agglomération Lyonnaise

Abstract : The aim of this thesis is to highlight and analyze the factors related to the spatial organization of the population and the economic activities which may produce a more sustainable mobility. By considering that the transport system is not sustainable, we measure mobility costs thanks to three indicators which represent the sustainability of household mobility: the annual costs of household urban mobility, the annual effort rate devoted by households to their transportation expenditures and the annual CO2 emissions. The link between urban form and mobility is not straightforward. Actually, it is a complex reciprocal link to be defined. The literature shows that three dimensions of local environment finally influence household mobility: density, diversity and accessibility. The method consists on confronting the factors alleged to explain the indicators of the sustainability of household mobility and on determining which part is explained by urban form. On the enlarged perimeter of the household travel survey of Lyon (2006), our approach based on household mobility costs enables, moreover, an approach to financial inequalities and introducing the notion of household vulnerability facing their transportation costs. In order to determine the share of mobility costs explained by urban form, we build some explanatory models, at the household level, by integrating urban form and socio-economic household variables. Especially the analysis focuses on the influence of secondary urban poles on the household vulnerability and mobility costs. Some explanatory models by household types show also that the effects of urban form are differentiated according to household categories. It is also interesting to measure the savings generated by marginal changes of urban form. To do that, we build some econometric models in a more aggregated level which allows computing elasticity coefficients. Thus, we can estimate, in economic terms, the expected savings that are triggered by urban form changes.
