Based on the transition to climate-neutral cities, the goal is to jointly take noticeable and remarkable steps towards a transformation of the mobility system in the cities in northern Sweden. We do this: - Together: a joint effort to establish a transition arena for mobility - Notable: We test actual solution that is noticed - Remarkable: The project is attracting attention - "something out of the ordinary" - System Transition: Together, our solutions encompass a systems perspective that includes technology, regulations, actors, collaborations, behaviour and visions. We encourage and spar each other to develop and implement innovations and strategies as well as to build knowledge, in an effort to increase diversity in travel habits. We integrate new transport modes and services and adapt new and existing urban environments. Together we create a long-term change in how people in northern Sweden travel and transport and drive sustainable development of cities in the north.
