Developing a wheelchair accessibility audit framework for urban redevelopment: a case study of Seoul’s Cheongjin district

This study develops and validates a systematic audit framework for evaluating wheelchair accessibility in Seoul’s urban redevelopment areas. Using a sequential mixed-method approach combining systematic literature review (PRISMA) and Focus Group Interviews with wheelchair users, the research establishes a comprehensive evaluation framework encompassing three domains: sidewalks, open space, and building access, integrating quantitative standards and qualitative criteria adapted to Seoul’s urban context. Applied to the Cheongjin district, a recently redeveloped area in Seoul’s historic centre, the evaluation reveals general compliance with basic physical accessibility requirements but identifies significant barriers to independent mobility. Major issues include heavy manual doors alongside revolving doors, conversion of rest areas into smoking zones, and inadequate alternative route information. These findings highlight a significant disparity between Seoul’s accessibility standards and actual usability outcomes, emphasizing the need for audit frameworks that bridge regulatory requirements and practical user experience to guide future urban redevelopment projects.
