The Integration of Analytic Hierarchy Process and Geographic Information System Methods to Analyze Accessibility in University Campuses: The Case of Osmanıye Korkut Ata University Karacaoğlan Campus, Turkey

University campuses located within cities function as small-scale urban living areas and are expected to be designed to ensure easy and equitable access for all segments of society. In this context, in the first stage of the present study, the criteria identified from the literature on campus-scale accessibility were presented to experts for weighting. The weighted criteria were scored using the AHP method by an expert group across four commonly used pedestrian axes within the campus. In the second stage, a Geographic Information System (GIS)-based composite Accessibility Suitability Index (ASI) was applied across the entire campus pedestrian network. Then, this index was combined with the renormalized AHP weights. The analyses revealed that at Osmaniye Korkut Ata University, Axis 1 fell into the “medium” category, while the other three axes were classified as “low.” Improvement proposals were developed to address the deficiencies identified in the study area. These recommendations are expected to positively influence environmental factors and boost pedestrian use on the Karacaoğlan Campus of Osmaniye Korkut Ata University.
