MaaSive project will be part of Shift2Rail (S2R), the first rail joint technology initiative focused on accelerating the integration of new and advanced technologies into innovative rail product solutions. It is framed within the innovation Program 4 (IP4), which addresses “IT solutions for attractive Railway services”. MaaSive continues and complements the work accomplished within previous projects, ATTRACkTIVE and CO-ACTIVE, in the areas of travel shopping, trip tracking, booking and ticketing, and the development of a travel companion. The project not only will enhance and provide extra functionalities to the existing IP4 ecosystem, but also makes emphasis in the compatibility of this ecosystem with the Mobility as a Service approach.
