1158 | 303 | The 15-Minute City: Analysing Accessibility to Essential Daily Destinations by Active Mobility in Seville | Miklós Radics (1)(2), Panayotis Christidis (1), Borja Alonso Oreña (2), Luigi dell’Olio (2)

The concept of the 15-minute city in essence covers the idea of connected, mixed-used, functionally dense cities where most daily needs can be reached with a short travel not taking longer than 15 minutes. Proximity of essential daily destinations and inclusive sustainable transport options allow people to travel less to meet their daily needs with a reduced environmental impact. In this framework both the number and the length of the trips are reduced. The 15-minute city is a responsive urban planning concept to various contemporary urban challenges and as such it is a potent solution for urban sustainability transition. _x000D_
We propose a reproducible and scalable methodology to analyse accessibility to essential destinations using open data and open-source software. We calculate accessibility metrics for different destination categories by active mobility. Based on these metrics we can evaluate the applicability and feasibility of the 15-minute city concept in the study area of the City of Seville. This approach lets us understand the differences in the performance of active mobility and how the urban fabric influences accessibility across the functional urban area. Besides that, census level socio-demographic data is used to analyse the related transport equity aspects. _x000D_
Using the results of the analysis we can identify areas where interventions are necessary for better infrastructure provision for active mobility or for densification of services. The efficient operation of various services is linked to an optimal service area and population. Accordingly, dense areas often outperform urban peripheries in terms of the quantity or diversity of accessible destinations. However, the relationship between accessibility and income variables are less evident, especially when wealthy, car-dependent neighbourhoods are considered. Based on our results, we also propose policy relevant recommendations to facilitate the implementation of the 15-minute city concept._x000D_
