Evaluation of Urban Accessibility Through Geomarketing Techniques: Case Study in Valencia (Spain)

Today’s world is becoming increasingly urbanised, with populations concentrated in cities. This trend underscores the need to monitor urban growth and its potential adverse effects. The 2030 Agenda for Sustainable Development, the European Urban Agenda, various local agendas, and the “15-Minute City” concept aim to mitigate these effects, particularly climate change-related ones. This paper explored the role of accessibility to public transport, services, and green urban areas (GUAs) in achieving the goals of SDG 11: Sustainable cities and communities and examined the feasibility of establishing 15-min cities by evaluating urban indicators. The methodology applied geomarketing techniques within geographic information systems (GISs) using high spatial resolution and influence buffers rather than conventional buffers for a more accurate assessment. These results offer a comprehensive and specific view of the city’s situation, based on the case study of Valencia (Spain), and provide urban planning tools for decision-makers with accessibility evaluated as a percentage at the block level.
