Aligning transit provision with urban morphology
Transit accessibility in cities is shaped not only by service provision but also by the extent to which transit networks align with the structural hierarchy of streets. This paper develops a reproducible, data-efficient framework that integrates angular segment analysis from Space Syntax, proximity-based transit catchments, and population-weighted exposure measures to assess how well transit stops correspond to high-integration corridors. Two ind…
Enhancing monitoring in protected areas
Crowdsourced data, such as that from mobile fitness apps (MFAs), has the potential to transform tourism research. This opportunity is particularly valuable as tourism to protected areas (PAs) increases, making it more difficult to manage their environmental impacts. However, such data sources come with challenges. Therefore, their representativeness should be carefully evaluated, particularly as their use continues to grow. We use the Paiva Walkw…
Assessing equity in the accessibility to urban greenspaces
Urban greenspaces are essential for the liveability of cities, due to their multi-functionality and the benefits they provide to the residents as ecosystem services. Their potential as nature-based solutions also provides an important opportunity to tackle and mitigate socio-economic and spatial inequalities, at various scales. Therefore, location and quality of greenspaces must be planned considering equity in the access by resident population, …
Using GPS tracking data from mobile fitness apps to understand user behaviour in protected areas
Protected areas are important environmental conservation sites, but their sustainability depends on effective management to mitigate the negative impacts of nature-based tourism. Data from Mobile fitness apps (MFAs) provide researchers and stakeholders with detailed spatiotemporal information regarding visitor movements, thereby facilitating a comprehensive understanding of visitor behaviour, the implementation of effective monitoring strategies,…
Recreational use of protected areas
Managing the rising number of visitors to protected areas (PAs) without compromising their environmental goals is a critical challenge that requires a complete understanding of how and when visitors use these spaces. Georeferenced data from fitness-tracking apps can provide detailed information about the visitor’s spatiotemporal behaviour inside PAs, but its potential is still underexplored. This study uses georeferenced data, from Wikiloc, to an…
Exploring the Spatial Relationship between Street Crime Events and the Distribution of Urban Greenspace
In post-pandemic, climate-changing societies, the presence of urban greenspace assumes paramount functions, at the same time that socio-economic crises and shocks augment vulnerabilities and insecurities. The recent literature on environmental criminology argues that the geography of crime is not random, and that the presence of greenery, due to its impact on well-being and the environment, can have positive associations with feeling safe; althou…
Urban Crime Prevention
Crime Prediction and Monitoring in Porto, Portugal, Using Machine Learning, Spatial and Text Analytics
Crimes are a common societal concern impacting quality of life and economic growth. Despite the global decrease in crime statistics, specific types of crime and feelings of insecurity, have often increased, leading safety and security agencies with the need to apply novel approaches and advanced systems to better predict and prevent occurrences. The use of geospatial technologies, combined with data mining and machine learning techniques allows f…
Mapping health vulnerabilities
Vulnerability processes and effects, albeit of great importance to cohesion and territorial policies, are nonetheless still underexplored and narrowly operationalized in scientific research. In particular, most assessments rely on economic indicators and a limited territorial scale, which do not have the same analytic potential of a broader view at a national level with regional/municipal similarities, specificities, and inter-connections. This g…
Community crime prevention in Portugal
Following the philosophy of other international programs as proximity policing or situational crime prevention, the Local Safety Contracts (CLS) have been an innovative strategy in Portugal, as they allow the sharing of accountabilities between the central and the local administration, in association with the police and the community. Nonetheless, little has been written in Portugal about such strategies, and nothing at all for the international …
Vacant Shops in a Crisis Period – A Morphological Analysis in Portuguese Medium-Sized Cities
Vacant shops are an important problem affecting urban areas today, particularly in the wake of the economic crisis. Most strategies to analyse and deal with this issue are related to economic and financial variables. However, the amount of research associating store geography and performance with urban morphology has increased over the past decade. Thus, this research tests the hypothesis that specific morphological features characterize vacant r…
Re‐Thinking Territorial Cohesion in the European Planning Context
The socio‐economic dimensions of cohesion have long been considered an integral part of Europeanization. However, recently a third dimension has been added to the Europe 2020 cohesion policy debate: territorial cohesion. Consequently this term is as yet undeveloped, resulting in a lack of consensus on how to define and interpret it. Such ambiguity represents a theoretical and empirical challenge to regional actors needing to respond to European U…
Dimensions of shrinkage
All over Europe, it is a known fact that cities are shrinking. One of the main causes is population decline, but the consequent reduction of urban area is neither immediate nor easy to foresee spatially. Questions arise such as where do cities start to ‘shrink’ first? What are the most fragile areas that face the risk of becoming derelict? What are the most vulnerable social groups? And how does this affect real estate values across the city? Exi…
