Mobility as a Service (MaaS) is conceived as the way people can move through customised mobility packages combining public and private services and offering a viable alternative to fragmented mobility and car ownership. The IMOVE project aims to accelerate the deployment and unlock the scalability of MaaS schemes in Europe, ultimately paving the way for a roaming service for MaaS users across different countries. Although a few MaaS initiatives have been piloted in Europe, most of them didn’t reach a significant scale and stable business operation. Overall, there is still a lack of a solid MaaS experience replicable at the EU level. IMOVE addresses the main challenges of MaaS development by investigating together innovative business and technology enablers and validating the designed solutions in four European Living Labs in Berlin, Gothenburg, Greater Manchester and Turin. A fifth European site, involved during project development through an open call launched at the European level, will help further assessing the transferability of developed IMOVE MaaS enablers and solutions.
