Urban access for every adolescent.

HANGOUT puts 14–18 year-olds at the centre of sustainable mobility planning — mapping their needs, breaking down barriers, and co-creating tools with them across four European cities.

About HANGOUT

Adolescents are the missing piece
in the 15-minute city.

The 15-minute city concept promotes proximity, accessibility and decarbonisation — but it largely overlooks the specific mobility needs and aspirations of adolescents aged 14–18 transitioning into adulthood.

HANGOUT addresses this gap head-on. Through comparative research across four European cities, Urban Living Labs in Lisbon and Holbæk, and open-source digital tools, the project puts young people at the centre of planning processes.

Our core research question: How can adolescent-inclusive urban mobility systems support sustainable transitions and strengthen young people's engagement in shaping their cities?

S1

Stage 1 — Diagnostic & Strategy

Background research, adolescent mobility data collection, governance mapping and benchmarking of policies and urban systems across four cities.

M1 – M16
S2

Stage 2 — Co-Creation & Tools

Urban Living Labs in Lisbon and Holbæk, participatory workshops with adolescents, and development of the HANGOUT Atlas and Policy Toolkit.

M13 – M34

Throughout — Dissemination

Engagement with the DUT Knowledge Hub, policy briefs, peer-reviewed publications, and open data to support cities across Europe and beyond.

M1 – M36
Specific Objectives

Four goals. One mission.

SO1

Understand mobility patterns & needs

Collect and analyse data on adolescents' lived accessibility experiences across four European cities, beyond school commutes.

SO2

Unlock barriers to sustainable choices

Identify and address structural, institutional, and spatial barriers limiting adolescents' access to sustainable mobility options.

SO3

Co-design through Urban Living Labs

Actively engage adolescents through ULLs in Lisbon and Holbæk, with Adolescent Councils driving co-creation of solutions.

SO4

Build replicable, scalable tools

Deliver the open-source HANGOUT Atlas and Policy Toolkit for adolescent-inclusive urban planning, tested across multiple cities.
