Review on mobility as a service in scientific publications

Our current private car based transport system is inefficient and unsustainable. The Mobility as a Service (MaaS) model aims to provide seamless trips over one interface by combining different transport modes and services. This study analyses MaaS-focused journal articles and conference papers found in Scopus and ScienceDirect databases in June 2018, and aims to help the scientific community and MaaS stakeholders to recognise the current state of the art of MaaS research findings, and where to focus in future. The recognised 31 MaaS-focused publications were categorised in three groups according to their main issues discussed; the roles of different transport modes and services in MaaS, the findings of MaaS pilots and trials, and the expected effects of MaaS. In these three categories, we present the key findings and discuss the future research avenues. The MaaS research has had a strong focus on private car users and how to change travel patterns of this user group. In order to attract new users, mobility services and sustainable transport modes should be able to provide a higher service level. A successful MaaS implementation is expected to be able to decrease the use of private cars and increase the use of sustainable transport modes.Peer reviewe
