Systematic mapping of scientific publications on MaaS

Mobility as a Service (MaaS) is a concept aiming for the provision of a diversity of transport services to travellers via one single user interface as one integrated service. The intention is to provide flexible mobility services to individuals and families to constitute an alternative to car ownership. This paper aims to provide an overview of the MaaS research area. A systematic mapping study of scientific literature on MaaS up till and including 2020 has been conducted. 193 articles are included in the study through searches in scientific databases and a structured selection and classification process. The findings are analysed and discussed. Eight main topics were identified in the MaaS literature: User aspects, Societal aspects, MaaS functionality, MaaS integration, MaaS implementation, Business aspects, Technology aspects, and Privacy and security aspects. The main results are: (i) Coding schemes defining the structure and scope of the MaaS research area with respect to the main topics and sub-topics, approaches used and contribution types; (ii) a classification of the selected literature on MaaS according to the coding schemes; (iii) analysis and discussions of the findings; and (iv) discussions of trends and gaps in the MaaS research. The study contributes to a broader and more detailed overview of the MaaS research area than previous work and can support the discovery of relevant literature, assist positioning of research within the research area, be used as a foundation for further literature studies, and guide the direction of future work on MaaS.
