The objective of SUM is to transform current mobility networks towards innovative and novel shared mobility systems (NSM) integrated with public transport (PT) in more than 15 European Cities by 2026 reaching 30 by 2030. Intermodality, interconnectivity, sustainability, safety, and resilience are at the core of this innovation. The outcomes of the project offer affordable and reliable solutions considering the needs of all stakeholders such as end users, private companies, public urban authorities. SUM project will develop five pillars consisting of technological, co-creation, and policy tools to tackle the identified NSM barriers for a typical, car-focused family. These five pillars can increase the modal share of NSM via targeted push/pull measures and policy recommendations. SUM will introduce a federation of solutions including prediction, scheduling, integrated NSM-PT ticketing, and real-time NSM management. This created ecosystem will reduce the total door-to-door travel times using integrated NSM-PT. This can change the behavior of 34% of travelers using cars and 17% of travelers sceptic about using NSM. The partners in this diverse consortium have access to innovative tools and expertise making them uniquely positioned to tackle the barriers in 9 living labs and 30 organizations across Europe.
