International audienceThe understanding of pedestrian mobility behaviors often relies on aggregated analyses. These analyses correlate spatial entities with the mobility streams that cross them. These types of approach are in particular developed to assess the impact of built morphology on pedestrian behavior. To go a bit further, we propose an unaggregated analysis, based on discrete choice models, and targeted on each pedestrian behavior. Thus, we check several morphometric indices with some route choices obtained during a survey in Strasbourg city. The result gives us confidence and shows that the method we present should be broadly distributed to exhibit the impact of built morphology on pedestrian mobility.La compréhension des comporte...
