Land Use Diversity and Daily Mobility: the Case of Bordeaux (by Guillaume Pouyanne) - ABSTRACT: The question of the urban form/daily mobility interaction has recently returned to the agenda. The aim of the Compact City model is to increase densities in order to reduce automobile use. However, the density/mobility interaction is called into question by the polycentric city: on the one hand, suburban employment centres produce original kinds of travel, such as cross-commuting or multi-purpose travelling; on the other, the co-location of jobs and housing is made easier. The idea is that land use mix brings the origins and the destinations of journeys closer together. The paper draws a distinction between two types of diversity: functional (i.e. the jobs/housing balance) and economic (i.e. the sectoral distribution of jobs). Both of these types may have an impact on daily mobility. The paper applies this distinction to the case of the metropolitan area of Bordeaux.
