Handicap de situation et accessibilité piétonne : reconcevoir l'espace urbain

Nowadays, public spaces have to be planned to allow a full accessibility for people with disabilities. The measures proposed to improve pedestrian mobility need to consider the surrounding space from the users’ point of view. However, urban space cannot be purged of any obstacles, since a favourable areas for some users can simultaneously be unfavourable to others. Therefore, disability is addressed as the result of a situation where the balance between urban planning and the user’s demands, according to his own physical characteristics, are inexistent or not efficient. A socio-spatial answer to the expectation of a “handicap of situation” approach seems to pass by the location and the identification of the nature of spaces at the scale of a neighbourhood, but also by adapted routes to users at the scale of a segment. To achieve this, a pedestrian-oriented data collection and analysis, an urban audit, is provided to complete a geographical information system and to configure potential moving restrictions in respect of various users.
