Urban accessibility has become an increasingly relevant topic in sustainable urban planning, with the 15-minute city concept as a prominent model for designing inclusive and climate-responsive cities. This study investigates the spatial distribution of accessibility conditions in four Spanish cities: Granada, Barcelona, Valencia, and Palma de Mallorca. Utilizing a highly-detailed 15-minute city map based on a grid of 100x100m and estimated walking travel times to a total of 27 everyday destinations, we aim to compare the accessibility levels across these urban areas and identify service allocation deficits._x000D_

The high spatial accuracy of the data allows for a nuanced understanding of accessibility patterns, highlighting the varying levels of service provision across the cities. In this comparative analysis, we assess the average walking time required for inhabitants to access essential services, such as healthcare, education, and retail, in each city. Furthermore, we identify specific areas where service allocation deficits are most pronounced, emphasizing the need for targeted interventions to enhance urban livability and sustainability._x000D_

In light of the findings, this study underscores the necessity to understand how international frameworks like the 15-minute city concept align with historical Mediterranean cities, which traditionally exhibit high accessibility levels. Recognizing the unique spatial and historical context of these cities is crucial for implementing the 15-minute city model effectively and ensuring its relevance in diverse urban settings. Moreover, by laying out the basic accessibility conditions, our analysis can also serve as a foundation for evaluating the impacts of future transportation policies, such as car diets or congestion pricing. This will enable urban planners and policymakers to make informed decisions on strategies that promote sustainable mobility while preserving the distinct characteristics of Mediterranean urban environments.
