T-PATH-UP15 (DUT partnership) is a multi-regional research project that works together with young people to co-create transformative mobility strategies in urban, suburban, and peri-urban areas. The project responds to interconnected contemporary challenges, including climate change, vulnerable transport infrastructure, youth exclusion, and socio-spatial inequalities.

The main aim of the project is to reclaim and strengthen the concept of the 15-minute city, which has often been oversimplified, politically instrumentalised, or drawn into ideological debates. T-PATH-UP15 grounds the 15-minute city in everyday realities and lived experiences, with a particular focus on the needs and perspectives of young people.

The project places the 15-minute city within a System of Provision (SoP) framework, understanding mobility as closely linked to other systems that support daily life, such as housing, education, work, leisure, and access to services. It explores how these systems interact through infrastructure (e.g. transport networks, green spaces, schools, housing), institutions (governance, regulation, finance), user practices (travel behaviour and everyday activities), and political and economic processes, which together shape youth mobility patterns.
