The concept of ‘Mobility as a Service’ (MaaS) has considerable potential for success in highly urbanised areas with a higher concentration of users. However, can it also work in small Alpine communities, and if so, how? These are the questions that the MENTOR project has aimed to address since its launch in late 2018. To evaluate the feasibility of MaaS in the Alpine context, the concept has been put into practice in two Alpine regions: Merano in the Autonomous Province of Bolzano (Italy) and Brig-Glis in the Canton of Valais (Switzerland). For the application of the concept of “mobility as a service” to be possible, the essential requirement, in addition to the digital aspect, is the presence of a set of mobility services strongly integrated around the public transport offer, which is the backbone of the system. Therefore, the MENTOR project’s pilot activities concentrated primarily on examining the potential of new services that are strongly integrated with public transportation.
