City Know-hows
How can cities like Brussels and Malta overcome barriers to active mobility and create healthier, more sustainable urban environments? Discover the challenges, strategies, and key insights from local stakeholders on paving the way for a transformative future of mobility. Through interviews with key stakeholders, we explore solutions like citizen involvement and organisational changes that can drive urban transformation and support sustainable, active mobility.

Target audience
Urban planners and designers; policy-makers and researchers working on active mobility and street transformations
The problem
Although active mobility interventions and street transformations have gained traction in recent years, different contexts are experiencing major barriers in their design and implementation, which ultimately hinder efforts to promote active modes of transport.
What we did and why
We conducted research in Brussels and Malta to understand the barriers to designing and implementing active mobility interventions. Through media content analysis and stakeholder interviews, we identified the challenges these cities face, ranging from socio-cultural to political and financial. We also identified strategies that can improve the acceptance and success of active mobility projects, aiming to create healthier and more sustainable communities.
Our study’s contribution
Our study provides a deeper understanding of the barriers to active mobility interventions in different contexts, including in very car-centric urban environments. The study highlights differences in socio-cultural, financial, political, and knowledge-related challenges. It shows how these factors influence each city’s transformation process and offers actionable insights. These findings can guide future mobility projects aimed at promoting sustainable, active mobility in urban areas.
Impacts for city policy and practice
We highlight the need for city policies to prioritize citizen involvement and organizational changes to overcome barriers in active mobility projects. By addressing socio-cultural, financial, political, and knowledge gaps, cities can improve the success of such interventions. Policymakers should focus on tailored solutions that enhance public acceptance and streamline project implementation, ultimately fostering more sustainable and healthier urban environments. These findings can inform future mobility strategies in similar urban contexts.

This study explores how urban playground design can either segregate or integrate children within the broader city fabric. By comparing Venice and Auckland, we illustrate how playgrounds in Venice encourage unstructured exploration, while those in Auckland limit engagement to isolated, structured zones. We propose strategies for urban design that foster inclusive and dynamic public spaces for children.

There is limited evaluation of whether green space interventions lead to more people using these spaces. This is partly due to the difficulty of collecting data on visits to green spaces. Mobile phone data may offer one solution, but are rarely made available to researchers. As such, there is less examination of whether these data are valuable. We accessed small area anonymised mobile phone GPS data for Liverpool (2021-2022). Using a case study of wildflower planting, we identified green spaces where wildflowers were planted. A synthetic control was then constructed to identify similar green spaces where planting did not take place. We then compared the number of visits post-intervention between the intervention and control green sites. Our paper also gives an empirical and methodological evaluation of the strengths and weaknesses of using mobile phone data, which can inform others on how to best use them.

Among the factors impacting functioning and quality of life in autism, aspects of the built environment have recently gained increasing attention. However, the opportunity of proposing a universal framework for cross-scalar examination of these factors remains largely unrealized.
By narrowing the focus to public transport, a key component of urban spatial structure and urban mobility, this study explores the applicability of the World Health Organization’s International Classification of Functioning, Disability, and Health (ICF) in examining the built environmental factors that influence autism.
