Analyse des interactions entre étalement urbain, offre et demande en transport

Urban sprawl is a phenomenon that is becoming more and more widespread, transforming the urban landscape and the mobility habits of residents over the years. Reflections on sustainable development and daily mobility are closely linked to understanding the challenges that this phenomenon generates. Anticipating mobility needs enables informed decisions to be made for the development of transport networks and infrastructures. This anticipation would benefit from understanding the interactions between urban sprawl, transport supply and demand. This subject is all the more critical when we observe the speed of propagation of urban sprawl for the Canadian areas, which is growing much faster in the suburbs than in the urban city center (D. Gordon et al. 2018). This research sheds light on the interactions between three major spheres: urban sprawl, transport supply and transport demand. The notion of urban sprawl may seem intuitive, but it is a phenomenon whose definitions and measures vary. To characterize it objectively requires a synthesis of definitions and calculation measures. The general methodology adopted consists of the separate analysis of the three spheres first and then a cross-analysis of the results obtained to clarify the combined impacts and effects of the changes observed.
