The IP4MaaS project aims to plan and conduct demonstrations in Athens, Barcelona, Liberec, Osijek, Padua, and Warsaw testing technologies developed under the Innovation Programme 4 (IP4) of the Shift2Rail Joint Undertaking. IP4MaaS adopts an iterative planning process that will enable two iterations of the demonstration scenario definition. The two iterations are named, respectively, C-REL (Core Release) and F-REL (Final Release). The IP4MaaS C-REL demonstration scenario definition (included in D2.2) focused only on the Barcelona, Athens, and Padua demonstration sites. The IP4MaaS F-REL demonstration scenario definition considers a new set of IP4 functionalities to be demonstrated in all the six IP4MaaS demonstration sites (including Liberec, Osijek and Warsaw). This document provides:  An updated picture of the software services that are available in each demonstration site for integration in the Shift2Rail digital ecosystem. Technical information regarding these software services has also been uploaded on the Asset Manager to facilitate its sharing with CFM (Calls From Members) project partners.  An overview of users’ needs and expectations with respect to IP4 travel experiences, as they emerged from a conversational survey administered to travellers from demonstrations sites (and beyond) and an opinion mining activity run on social media  A description of the updated methodology adopted by the IP4MaaS project for the definition of demonstration requirements and scenarios. Some of the steps of the methodology, described in deliverable D2.2, are updated considering the feedback and experience from C-REL.  The results of the application of the methodology for the demonstration scenario definition for F-REL to the Barcelona, Athens, Liberec, Osijek, Padua, and Warsaw demonstration sites.  As result of all the above, the list of Shift2Rail IP4 functionalities that are candidated to be tested by IP4MaaS for each involved demonstration site. The C-REL and F-REL demonstration requirements and scenarios defined in this document will be further analysed within IP4MaaS WP4 to define a comprehensive roadmap toward each IP4MaaS demonstration. At the time of writing, two demonstration phases are foreseen: the first phase focusing on Athens and the second phase focusing on all other demonstration sites. This, however, may be subject to change due to the collaboration with CFM projects. Time plan, role assignments, and risks & mitigation measures for demonstrations will be provided, together with a detailed technology integration plan, in “D4.3: Demonstration Execution Plan and Technology Integration Plan, F-REL”
