Mobility as a service (MaaS) is a type of service that, through a joint digital channel enables users to plan, book, and pay for multiple types of mobility services. The concept describes a shift away from personally-owned modes of transportation and towards mobility provided as a service. This is enabled by combining transportation services from public and private transportation providers through a unified gateway that creates and manages the trip, which users can pay for with a single account. Users can pay per trip or a monthly fee for a limited distance. The key concept behind MaaS is to offer travelers mobility solutions based on their travel needs. Specialist urban mobility applications are also expanding their offerings to enable MaaS, such as Transit, Uber and Lyft.
