A call for abstracts for the joint workshop of NECTAR Cluster 4 (Urban Mobility Transitions) and Cluster 6 (Accessibility) which will be held at the University of Porto, Porto, Portugal, 14–15 September 2026.
Achieving sustainable urban mobility is a central challenge for contemporary cities, closely linked to climate action, social inclusion and urban quality of life. However, mobility systems can only become truly sustainable if everyday activities are organised at short distances. Physical proximity is not merely one option among many forms of sustainable mobility; it is a foundational condition that enables walking and cycling, reduces reliance on motorised modes, frees up public space and supports more inclusive urban environments accessible to people of all ages and abilities.
This workshop focuses on how empowerment-oriented approaches can help overcome car-dependent lock-ins and support sustainable mobility grounded in proximity.
In this workshop, we aim to bring together researchers, planners, practitioners and industry
representatives on the theme of empowering transitions to the x-min city. The workshop is back-to-back with the consortium meeting of the UNLOCK15 project (https://unlock15.eu/), focussed on empowering citizens and local authorities to unlock barriers.
Topics of interest include (but not limited to):
- New narratives and compelling stories inspire change in urban mobility.
- Evidence of new mobility cultures among young generations.
- The role of proximity-centred accessibility conditions in sustainable transitions.
- Modal shift and behaviour, promoting sustainable transport modes.
- Equity, fairness, and social issues, addressing urban inequalities.
- Multilevel governance and stakeholder collaboration.
- Governance structures supporting transformative capacity.
- Citizen involvement in mobility projects.
- Innovative solutions and experimentation in mobility.
- Stakeholder engagement.
If you are interested to participate in this workshop, please send an abstract of your presentation (about 500 words) including author names and affiliations and keywords, to (see details in pdf) before June 15, 2026. The notification of abstract acceptance will be distributed June 30, 2026.
