The idea of MaaS (Mobility as a Service) has been a topic of interest for some time, both in Finland and abroad. MaaS has broad effects in the development of society and service businesses. MDI carried out an effectiveness study of MaaS. The work focused on gathering, filtering and simplifying information. The work had three phases: 1) trends, 2) roles and 3) road map. The most important task was to reinforce decision-makers’ understanding of the possibilities of MaaS, creating a favourable ecosystem and linking MaaS into other development themes. The work was finalised in August 2015.
