Paysages et choix d'itinéraires pédestres en milieu urbain. Une nouvelle approche par les bifurcations

subject

description

Walking has long been neglected in urban mobility research. In the context of a sustainable mobility, it is now included into numerous works including various approaches. The well-known models of flows affectation are often used to study the behaviour of pedestrians and to identify their preferences. However, the factors that are usually chosen to describe the urban environment are usually limited or inappropriate to the pedestrian movement. In addition, these models assume that the choices made by pedestrians are predetermined at the start of each trip, without any possible decision intervening along these trips. In this paper, we propose to test the role of urban landscape by using a new route choice analysis method. An algorithm is used to find the “junctions”, i.e. the crossroads from which pedestrians chose a route longer than the shortest path. A set of junctions allows us to apply a discrete choice model in order to evaluate the influence of urban landscapes.
