The initiative „Urban Mobility Labs“ (UML), promoted by the Austrian Ministry of Transport, Innovation and Technology, was initiated to support the setup of innovative and experimental environments for research, testing, implementation and transfer of mobility solutions. This should happen by incorporating the scientific community, citizens and stakeholders in politics and administration as well as other groups. The emerging structural frame shall enhance the efficiency and effectivity of the innovation process. This paper gives insights and in-depth analysis of the approaches and experiences gained in the eight UML exploratory projects. These projects were analysed, systematized and enriched with further considerations. Furthermore, knowledge growth about user-centred innovation environments was documented during the exploratory phase.
