Using the City of Corvallis, Oregon, a small to medium sized American city, as a test-bed, this paper examines the City’s urban growth in relation to urban accessibility. This relationship is explored in an anatomic spatial-temporal fashion, taking account of: the number and size of developed land use parcels over time; urban accessibility from residential to non-residential land use areas; and the statistical relationships between urban form and urban accessibility. This investigation of land use is structured around use-classification and examined within a range of dimensional and demographic measurements over 5-year time periods from 1853 to 2014; concurrently, urban accessibility is measured by the least-cost path distance as calculated through the OD cost matrix analysis in GIS. The results indicate that the city grew spatially at different rates and its urban accessibility experienced both ups and downs over time. The city’s population growth corresponded closely with urban growth and its decreasing population density negatively impacted on the city’s urban accessibility to commerce, industry, and office for most time periods. Significantly, while the urban density increased steadily after 1950s concurrent with an increase in urban sprawl, in contrast to previous studies on the metropolitan condition, the urban density had no evident impact on urban accessibility in Corvallis. Instead, increasing the land-use mix was a more effective and feasible approach to reduce urban travel path distance and enhance accessibility than increasing population density or urban development density. Accordingly, this research provides evidence-based policy recommendations for planning sustainable urban mobility and urban form in small to medium-sized cities.

Urban accessibility represents one of the great challenges of the contemporary city, which is required to adopt sustainable development models in line with the UN Agenda 2030 objectives, recently confirmed by the health emergency. Urban accessibility and walkability are topics closely related to those aiming at a livable, healthy and inclusive city, based on a system of high-quality public spaces and on a network of services and infrastructures. However, these principles collide with the fragmentation of many urban contexts, built following vehicular accessibility needs. Within this framework, the city of Cagliari represents an interesting case study as it is affected by the disposal of public properties which appear as “enclaves” in the historic urban fabric. This research aims to evaluate if and in which terms the abandoned assets can facilitate the development of the 15-minutes city, as a city reducing the need to move over a certain time and space and therefore granting a more equal access to urban services to a wide range of citizens. This is done by proposing indexes defined as porosity, crossing and attractiveness, which constitute a combined index to improve the pedestrian accessibility in the “central places” of the contemporary city, where the walkability can also become a possible “free choice” for a new healthy lifestyle. These indexes were calculated for the most significant large disused public buildings in the historic center to guide future scenarios towards a 15 minutes city.

The concepts of accessibility and urban walkability are the cornerstones of urban policies for the contemporary city, called upon to adopt sustainable development models in line with the objectives of the 2030 Agenda and the ambitious objectives of the 'European Green Deal'. These concepts are closely linked to the paradigm of a sustainable city (livable, healthy and inclusive), founded on a system of quality public spaces and on a network of services and infrastructures, both tangible and intangible, capable of strengthening or building new relationships: social, economic and environmental. It is therefore necessary to recognize potential opportunities for connection and permeability in consolidated urban environments, very often fragmented and characterized by enclaves. Within this framework, the city of Cagliari represents an interesting case study as it is characterized by the presence of a series of military complexes, real 'enclaves' which condition the proximity connections and, more generally, the walkability. In this sense, building on previous research and analysis of policies and projects aimed at reintroducing, even partially, this military asset into civilian life (Green Barracks Project - GBP - 2019), this study proposes and applies a methodology to improve urban accessibility in a flexible network logic, where 'walkability' can become not only a moment of possible "choice" but the basis for planning oriented to the '15 min city' model or, more generally, to the renewed, inclusive, safe, resilient and sustainable “City of proximity”.

Cities demand urgent transformations in order to become more affordable, livable, sustainable, walkable and comfortable spaces. Hence, important changes have to be made in the way cities are understood, diagnosed and planned. The current paper puts urban accessibility into the centre of the public policy and planning agenda, as a transferable approach to transform cities into better living environments. To do so, a practical example of the City of Monterrey, Mexico, is presented at two planning scales: the metropolitan and local level. Both scales of analysis measure accessibility to main destinations using walking and cycling as the main transport modes. The results demonstrate that the levels of accessibility at the metropolitan level are divergent, depending on the desired destination, as well as on the planning processes (both formal and informal) from different areas of the city. At the local level, the Distrito Tec Area is diagnosed in terms of accessibility to assess to what extent it can be considered a part of a 15 minutes city. The results show that Distrito Tec lacks the desired parameters of accessibility to all destinations for being a 15 minutes city. Nevertheless, there is a considerable increase in accessibility levels when cycling is used as the main travelling mode. The current research project serves as an initial approach to understand the accessibility challenges of the city at different planning levels, by proving useful and disaggregated data. Finally, it concludes providing general recommendations to be considered in planning processes aimed to improve accessibility and sustainability.

Abstract Due to the increased tendency to use private transport in urban areas of Manizales and Villamaría municipalities, it is intended to include alternative modes of transport that are more time-efficient and environmentally sustainable to improve the inhabitants’ quality of life. This article aims to analyse the inclusion impact of a sustainable public transport system, such as a new cableway line in the city connecting the Central Business District (CBD) with Ciudadela del Norte district, measuring overall average accessibility for the current and future scenario. This establishes the average travel time and the savings in terms of time shown as a percentage that these modes of transport would create in the population displacement and also which inhabitants are the most likely to benefit.

As urban populations grow worldwide, it becomes increasingly important to critically analyse accessibility – the ease with which residents can reach key places or opportunities. The combination of ‘big data’ and advances in computational techniques such as machine learning (ML) could be a boon for urban accessibility studies, yet their application remains limited in this field. In this study, we aim to more robustly relate socio-economic factors to healthcare accessibility across a city experiencing rapid population growth, using a novel combination of clustering methods. We applied a powerful ML clustering tool, the self-organising map (SOM), in conjunction with principal component analysis (PCA), to examine how income shifts over time (2016–2022) could affect accessibility equity to healthcare for senior populations (65+ years) in the City of Surrey, Canada. We characterised accessibility levels to hospitals and walk-in clinics using door-to-door travel times, and combined this with high-resolution census data. Higher income clusters are projected to become more prevalent across the city over the study period, in some cases incurring into previously low income areas. However, low income clusters have on average much better accessibility to healthcare facilities than high income clusters, and their accessibility levels are projected to increase between 2016 and 2022. By attributing temporal differences through cross-term analysis, we show that population growth will be the biggest accessibility challenge in neighbourhoods with existing access to healthcare, whereas income change (both positive and negative) will be most challenging in poorly connected neighbourhoods. A dual accessibility problem may therefore arise in Surrey. First, large senior populations will reside in areas with access to numerous, and close-by, clinics, putting pressure on existing facilities for specialised services. Second, lower-income seniors will increasingly reside in areas poorly connected to healthcare services; since these populations are likely to be highly reliant on public transportation, accessibility equity may suffer. To our knowledge, this study is the first to apply a combination of PCA and SOM techniques in the context of urban accessibility, and it demonstrates the value of this clustering approach for drawing planning policy recommendations from large multivariate datasets.

Resumen Los procesos de movilidad urbana en las ciudades latinoamericanas se enfrentan a un territorio fragmentado, desigual, no inclusivo, que altera y fragmenta las condiciones espacio-temporales sobre las cuales se construye la espacialidad urbana de la vida cotidiana, y por ende afecta sus desplazamientos. Es por lo que se hace necesario estudiar las prácticas sociales de viajes y la relación directa con el capital de motilidad que ostenta un individuo y que le permite ejercer su habitus ambulante. En la zona periférica de Tahuantinsuyo en la ciudad de Lima (Perú), se aplicó un método etnográfico, de tipo micro-etnografía-particularista, combinando observación no participante y entrevistas semi-estructuradas, lo que permitió la recolección de datos cuantitativos y cualitativos para caracterizar la condición de accesibilidad, competencias, agencia y apropiación con el fin de determinar el capital de motilidad. Como resultado se determinó que este capital es alterado en función no solo a la posición socio-económica y la competencia con otros agentes, sino también, en relación a su grado de accesibilidad a su hábitat, sus capacidades físicas, habilidades o competencias, encontrando diversas y coincidentes prácticas sociales de viajes que alteran dicho capital.

That is why it is necessary to study the social travel practices and the direct relationship with the capital of motility that an individual has and that allows him to exercise his traveling habitus. In the peripheral area of ​​Tahuantinsuyo in the city of Lima (Peru), an ethnographic method was applied, of the micro-ethnography-particularist type, combining non-participant observation and semi-structured interviews, which allowed the collection of quantitative and qualitative data for characterize the condition of accessibility, competencies, agency and appropriation in order to determine the motility capital. As a result, it was determined that this capital is altered based not only on the socio-economic position and competition with other agents, but also, in relation to their degree of accessibility to their habitat, their physical abilities, skills or competencies, finding various and matching social travel practices that alter said capital.

The problem of urban accessibility for persons with mobility restrictions has been for some years a subject of discussion both within academic communities and communities of physically restricted transit users. Some have argued the issue lies within the spaces created by those whose experience of the city is dependent on transit rather than automobile use, or who use wheelchairs rather than walk. This paper attempts to advance what has been a largely experiential literature into a more sustained argument that develops a program to describe the altered spaces created by different transit modalities for users with different abilities. With a review of the literature it begins with the author's own experience and the means by which it led to a new transit initiative focused upon surface analytics in transit analysis rather than a more traditional mode of consideration.
