A polyline-based spatial GIS database has been developed to demonstrate how physical barriers and transitions could be modeled in micro scale in GIS environment in order to evaluate physical accessibility. The results of the study could provide an accessibility based decision support environment by visualizing and presenting how physical obstacles in urban space prevent physically disabled users from access and circulation and how the elimination or removal of these physical obstacles and creation of transitions will create a difference in access and circulation for the users in a comparable manner especially in micro scale.</p><p>This study is thought to make a significant contribution to increase accessibility levels of physically disabled users (users using wheelchair, bicycle, baby's car, market car etc.) in the outdoor urban areas in terms of demonstrating their accessibility and circulation capabilities.</p><p>The first primitive experimental model related with this research was carried out with the participants of the accessibility measurement and modeling session at the 3rd National Disability Workshop which is held in Selcuk University, Mimar Muzaffer Campus dated 2-3 May 2018.</p>}, journal={ICONARP International Journal of Architecture and Planning}, author={Ertuğay, Kıvanç}, year={2018}, month={Aug.}, pages={81–104} }
