Co-Creating Accessibility-Centred Mobility Strategies in Low-Density Suburban Contexts: Evidence from Coimbra, Portugal José Gomes, João Monteiro, Anabela Ribeiro, Marta García Urban Science, 2026 Promoting and increasing sustainable mobility has become more of a focus in transport and mobility policies and plans. However, challenges remain in its implementation in low-density urban areas, which are usually highly dependent on private motorised transport. This study investigates how local actors and citizens in a low-density suburban area perceive the main mobility challenges and opportunities, contributing empirical evidence on how collaborative planning operationalises accessibility-oriented mobility models in low-density suburban territories, an under-researched context in sustainable mobility. It also examines how co-creation processes contribute to identifying barriers and priorities and to what extent proximity-based concepts such as the 15-Minute City, Transit-Oriented Development (TOD), and Mobility as a Service (MaaS) can be reinterpreted for low-density suburban realities. The methodological approach involved three focus groups with local actors and citizens to identify barriers, priorities, and strategies through collective discussion and co-creation. This process resulted in an agreement on eight (8) co-created strategies, revealing convergence towards promoting active modes and public transport and emphasising that accessibility depends on territorial redesign, digital integration, and inclusive governance. The findings contribute to the empirical evidence that participatory and context-sensitive approaches can enable sustainable mobility transitions in suburban areas by efficiently meeting people’s needs and aspirations.
Walking to Public Transport: Rethinking Catchment Areas Considering Topography and Surrogate Buffers Filipe Pais, Nuno Sousa, João Monteiro, João Coutinho-Rodrigues, Eduardo Natividade-Jesus ISPRS International Journal of Geo Information, 2025 Service, or catchment areas of public transport stops are traditionally assessed using Euclidean or network distances, often neglecting other relevant factors such as topography. This study proposes a refined approach that integrates network-based accessibility with terrain variations and the effect they have on walking time and on the physical effort required for pedestrian movement. Using geographic information systems-based analysis that include walking time and walking energy cost models, the impact of topography on accessibility to public transport is evaluated in a case study of the hilly city of Coimbra, Portugal. Results show that, as compared to their flat counterparts, network distance-based service areas that consider hilliness, exhibit a decrease in accessibility of circa 10% in terms of area covered and population affected. These findings highlight the need for more realistic accessibility assessments to support more realistic and equitable public transport planning. Because extensive network datasets are not always available to decision-makers, this article also introduces the concept of surrogate buffers as a practical alternative for obtaining catchment areas, summarized by the “0.7/0.6R rule”.
Do people adapt to where they live? A comparative analysis of perceived physical urban pleasantness using a quantitative model João Monteiro, Patrícia da Silva Santos, Nuno Sousa, Eduardo Natividade-Jesus, João Coutinho-Rodrigues, et al. Urbe, 2025 This article examines the question of whether people perceive their own urban environment more favourably than people from other urban environments, i.e., whether residents, in a sense, adapt to where they live. To analyse this question, a quantitative statistical model that uses geometric and land use elements was applied to a case study of Belo Horizonte, Brazil, to estimate the perception of physical pleasantness of the urban environment using two calibrations: a global one and one obtained from a survey carried out in Belo Horizonte. The article then contrasts findings specific to Belo Horizonte with global perceptions, highlighting that local residents tend to evaluate their city's geometry and land use more positively than a worldwide audience. This difference suggests that familiarity and acclimatisation to the urban environment can significantly influence residents’ perceptions of their physical living environment.
Challenges Ahead for Sustainable Cities: An Urban Form and Transport System Review João Monteiro, Nuno Sousa, João Coutinho-Rodrigues, Eduardo Natividade-Jesus Energies, 2024 This article reviews the critical issues surrounding the development of sustainable urban environments, focusing on the impact of transport and urban form on energy consumption and greenhouse gas emissions. The aim is to provide an overview of the state-of-the-art on the subject and to unravel what directions the literature suggests for sustainable urban planning. Current research and practices are synthesized, highlighting the interdependence of urban design and transportation systems in achieving sustainability goals. Important dimensions and practices of city planning and transport policies are explored, including urban form, urban sprawl, mixed land use, densification and infill, and urban public spaces, and how these directly influence transport dynamics, including modal choices and energy consumption. Innovative approaches in urban planning, such as transit-oriented development, and technological advancements, such as electric mobility, are also examined and their potential roles in sustainable urban transport. The conclusion underscores the urgency of adopting holistic and adaptable strategies to foster sustainable urban environments, calling for concerted efforts from policymakers, urban planners, and communities. Awareness of the conclusions can help municipal decision-makers in planning their cities for a sustainable future. Finally, the authors analyze important directions for future research and practical applications towards developing cities that are environmentally sound, socially equitable, and economically viable.
Do We Live Where It Is Pleasant? Correlates of Perceived Pleasantness with Socioeconomic Variables João Monteiro, Ana Clara Carrilho, Nuno Sousa, Leise Kelli de Oliveira, Eduardo Natividade-Jesus, et al. Land, 2023 Living in urban areas is the wish of many people. However, with population growth in those areas, quality of life has become a concerning element for achieving sustainable cities. Because quality of life is influenced by the built environment, the state of the latter is a fundamental issue for public policies. This research expands on previous research on the perceived pleasantness of built environments by presenting a large-scale case study of the urban layout pleasantness in the central area of Belo Horizonte, Brazil, a typical global south city, and correlating pleasantness scores with socioeconomic factors to understand whether people do in fact live where the urban layout is more pleasant and how pleasantness and socioeconomic factors relate and contribute to one’s choice of living location. A comparison with the city of Coimbra, Portugal, representative of the global north, was also carried out. The findings showed that pleasantness tended to correlate negatively with urban density and positively with income. Possible explanations for these results and their generality are advanced.
Planning cities for pandemics: Review of urban and transport planning lessons from COVID-19 João Monteiro, Nuno Sousa, Filipe Pais, J. Coutinho-Rodrigues, Eduardo Natividade-Jesus Proceedings of the Institution of Civil Engineers Municipal Engineer, 2023 For the past years, the world has been facing one of the worst pandemics of modern times. The COVID-19 outbreak joined a long list of infectious diseases that turned pandemic, and it will most likely leave scars and change how we live, plan, and manage the urban space and its infrastructures. Many fields of science were called into action to mitigate the impacts of this pandemic, including spatial and transport planning. Given the large number of articles recently published in these research areas, it is time to carry out an overview of the knowledge produced, synthesising, systematising, and critically analysing it. This article aims to review how the urban layout, accessibility and mobility influence the spread of a virus in an urban environment and what solutions exist or have been proposed to create a more effective and less intrusive response to pandemics. This review is split into two avenues of research: spatial planning and transport planning, including the direct and indirect impact on the environment and sustainability.
The impact of geometric and land use elements on the perceived pleasantness of urban layouts Nuno Sousa, João Monteiro, Eduardo Natividade-Jesus, João Coutinho-Rodrigues Environment and Planning B Urban Analytics and City Science, 2023 This article presents a model to estimate the impact of geometric and land use elements on citizens’ perception of urban layout pleasantness. An ordinal regression cumulative link mixed model with those elements as regressors is proposed and calibrated using data from an online survey. Results show that landscape building height and density of green areas are the factors that most impact the perception of pleasantness. Based on the model, a methodology to derive pleasantness mean scores for a city is also proposed and applied to a case study. The methodology allows for benchmarking the pleasantness of different cities or comparing neighborhoods within a city. It can be used both as an urban evaluation tool and a decision-aid for city expansion programs.
Filling in the Spaces: Compactifying Cities towards Accessibility and Active Transport João Monteiro, Marvin Para, Nuno Sousa, Eduardo Natividade-Jesus, C. Ostorero, et al. ISPRS International Journal of Geo Information, 2023 Compactification of cities, i.e., the opposite of urban sprawl, has been increasingly presented in the literature as a possible solution to reduce the carbon footprint and promote the sustainability of current urban environments. Compact environments have higher concentrations of interaction opportunities, smaller distances to them, and the potential for increased active mode shares, leading to less transport-related energy consumption and associated emissions. This article presents a GIS-based quantitative methodology to estimate on how much can be gained in that respect if vacant spaces within a city were urbanized, according to the municipal master plan, using four indicators: accessibility, active modal share, transport energy consumption, and a 15-minute city analysis. The methodology is applied to a case study, in which the city of Coimbra, Portugal, and a compact version of itself are compared. Results show the compact layout improves all indicators, with averages per inhabitant improving by 20% to 92%, depending on the scenario assumed for cycling, and is more equitable.
The Potential Impact of Cycling on Urban Transport Energy and Modal Share: A GIS-Based Methodology João Monteiro, Nuno Sousa, Eduardo Natividade-Jesus, João Coutinho-Rodrigues ISPRS International Journal of Geo Information, 2023 This article presents a methodology to estimate the maximum potential impact of a well-built and conserved cycling infrastructure, measured as modal share for accessibility trips, as well as the associated transport energy that can be saved in those trips. The methodology uses Geographic Information Systems (GIS) to estimate active trip probabilities, from which the output variables can be obtained. It was applied to a case study of a mid-sized city in Southern Europe, and results show that an adequate cycling infrastructure can achieve cycling mode share in that city on par with the world’s most cycling-friendly cities. Concerning transport energy, a full-cycling scenario is estimated to reduce fossil energy intensity by approximately 20%, mainly by inducing a mode change for residents on the closest outskirts. It is also argued that cycling investment in commuting routes will have the most impact on reducing fossil transport energy.
