The idea of MaaS (Mobility as a Service) has been a bubbly topic for over a year in Finland and abroad. MaaS has wide effects in development of society and service businesses. MDI carried out a broad 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 essential task was to reinforce the decision-makers’ understanding of possibilities of MaaS, creating a favourable ecosystem and linking MaaS into other development themes. The work was due in August 2015.
