    Spatial Proximity and Accessibility Patterns of X-Minute Cities
    (Elsevier Ltd, 2026) Östh, John; Türk, Umut; Kourtit, Karima; Nijkamp, Peter
    The 15-minute city concept has gained prominence in urban planning as a framework linking proximity, mobility, and quality of life at the intra-urban scale. An open question is whether this concept remains meaningful when applied to spatially connected urban regions or national urban systems. To address this issue, the new X-minute city concept allows proximity thresholds to vary with spatial context, mobility conditions, and service distribution. This paper develops an operational framework with the aim to examine and highlight spatial accessibility patterns from an X-minute city perspective, using the relatively urbanized area of the Netherlands as a national-scale case study. Accessibility is analyzed at the building level using OpenStreetMap data and a combination of object-based k-nearest-neighbor measures, distance-decay functions, inequality metrics, Average Nearest Neighbor analysis, and quantile regression. Concepts from central place theory are employed as an interpretive lens to understand service clustering and accessibility patterns, rather than as a formal model to be tested. The results show pronounced spatial disparities in accessibility between urban and rural areas, as well as substantial variation within cities. Major urban centers such as Amsterdam, Rotterdam, and Utrecht exhibit high accessibility levels due to dense service provision, while peripheral and rural areas face systematically lower accessibility. Next accessibility outcomes also differ sharply across population groups. Elderly residents and groups reliant on walking experience the highest levels of inequality, with accessibility distributions remaining highly uneven at short-distance thresholds. Cycling expands the range of effective activity spaces and reduces inequality, but does not offset structural disadvantages in areas with sparse service provision. The findings point to the limits of uniform proximity targets and reveal the need for context-sensitive accessibility planning that explicitly accounts for service distribution, mobility constraints, and population heterogeneity within national urban systems.

    Spatial Competition, Spatial Agglomeration and Survival of Small Businesses in Milan During COVID-19
    (Societa Editrice Il Mulino, 2023) Türk, Umut; Östh, John
    This study examines the location choice of small firms in Milan across three periods: pre-COVID, early COVID, and late COVID, testing the applicability of traditional spatial economic theories. With the recent COVID-19 pandemic restricting human mobility, there has been a significant acceleration of tele-activities such as remote work and e-commerce, which may have impacted consumer behavior and service supply. Using data extracted from open map services, we find that small businesses have become more residential but moved farther from the city center during the pandemic, with single-owned and multi-branch firms exhibiting different responses. © 2023 Elsevier B.V., All rights reserved.

    Is City Love a Success Factor for Neighbourhood Resilience? Results From a Microcosmic Analysis of Rotterdam
    (Springer Science and Business Media Deutschland GmbH, 2022) Kourtit, Karima; Nijkamp, Peter; Türk, Umut; Wahlström, Marie H. Hårsman
    This study examines and tests the concept of ‘city love’ in the context of social resilience for urban neighbourhoods. It introduces the notion of ‘city body’ and ‘city soul’ so as to create an operational framework for measuring the citizens’ appreciation and attachment for the local neighbourhood. Particular attention is given to the social bonds in urban community networks and language groups. A quantitative statistical analysis is carried out to test the relationships and determinants of city (or neighbourhood) love, based on extensive statistical, survey and social media data on the city of Rotterdam. © 2025 Elsevier B.V., All rights reserved.

    City Love and Place Quality Assessment of Liveable and Loveable Neighbourhoods in Rotterdam
    (Elsevier Sci Ltd, 2022-08) Kourtit, Karima; Nijkamp, Peter; Tuerk, Umut; Wahlstrom, Mia; Türk, Umut
    After the worldwide interest in global sustainability and climate change challenges, an increasing concern is voiced on local quality of life and neighbourhood liveability. In recent urban studies, human well-being, satisfaction and happiness studies are gaining much popularity in a local context (the 'microcosmic city'). The present study seeks to identify the determinants of the residents' appreciation for their daily environment, called here 'city love'. The latter concept captures both tangible or material aspects of city life ('body') and immaterial and emotional dimensions of local quality of life ('soul'). The present paper seeks to develop and test a new quantitative 'city love' concept, inspired by the soul and body conceptualisation of urban attractiveness for residents and visitors - based on a novel 'feelgood' index (FGI) and a 'human habitat' index (HHI) -, with a view to map out the citizens' contentment or appreciation (called neighbourhood love index - NLI) at a district or neighbourhood scale in the city of Rotterdam. Our study utilises data from a quantitative survey among thousands of residents located in 63 neighbourhoods in this city. In addition, the Rotterdam dataset contains not only survey data, but also register data on these neighbourhoods, e.g., real-estate values, crime statistics, and socio-demographics, while geographical information from OpenStreetMap (OSM) is added as a complement. In addition to a multivariate analysis of the rich data set, the paper employs also a quantile regression analysis extended with fixed effects. The results show that the coefficients of the feelgood index (FGI) and the human habitat index (HHI) decrease slightly as we move up the distribution of the neighbourhood love index (NLI). This means that physical and functional aspects of neighbourhoods, e.g., access to such amenities as public transportation, sport facilities, and also streets with diverse attractions or bikeable and walkable road networks, become more important for the lower end of the distribution of the neighbourhood love index (NLI). Our neighbourhood-specific analyses show that the Rotterdam districts and neighbourhoods differ substantially in many physical and social-emotional respects, which calls for place-based policies and sub-local well-being initiatives.
