ABSTRACT
Building on an existing model of the demand for mobility at the urban level, our main contribution consists of refining the spatial description of things within this model, to better describe the mobility of a district. Spatial refinement within the district has a twofold effect on the spatial distribution modelling stage: on internal trips within the district, and other trips exchanged with the rest of the territory. Despite the limitations mentioned above, spatial refinement addresses two issues in district-scale transportation modelling. Firstly, specification of the conditions for pedestrian access between the micro-zone centroid and the transport networks is refined for micro-zones. Secondly, the distinction of modal trip conditions for micro-zones is given in relation to the complementary zone at the other trip end. The spatial refinement of the CD district makes it possible to identify the flows exchanged between the buildings within the district and to allocate them on a local network described more finely than the initial network.
