This study clarifies the transition of subway stations and exits by literature survey and defines the PVA: Physical and Visual Accessibility. Then through the cluster analysis using the data based on field survey, it evaluates PVA of exits placed with urban development projects. The results show that station space and PVA become altered along with various restrictions of station construction. In terms of exits placed with urban development projects, these have various types and these PVA are unstable because government evaluates not exit's quality like PVA but existence.
