The Optimal Mix – Rethinking the Future of Mobility

UNIL, HEC Lausanne – Bilingual English & French

How can we design a mobility system that is sustainable, efficient, and fair?
In this interactive workshop, participants will take on this challenge through The Optimal Mobility Mix, a serious game exploring the complex trade-offs that shape our transport choices and urban futures.
Working in teams, players will design their own “mobility mix” — a combination of transport modes (public transit, cycling, walking, driving, etc.) that must balance several often conflicting goals: economic efficiency, emissions reduction, social inclusion, public health, and quality of urban life.
The game invites discussion, negotiation, and creativity as participants strive to find their version of an “optimal” solution. Engaging, collaborative, and thought-provoking, The Optimal Mobility Mix opens space for reflection and dialogue around the challenges of climate action and sustainable urban transition.
At the end of the session, each group will share its proposed mix and the reasoning behind it — highlighting how our mobility choices mirror our collective values and visions of the future.
