RIDE2RAIL aims to integrate multiple (public/private/social) data sets and sources and existing transport platforms to promote an effective Ride Sharing practice of citizens, making it a complementary transport mode that extends public transport and rail networks. The RIDE2RAIL framework for intelligent mobility will integrate and harmonise real-time and diverse information about rail, public transport, ride-sharing and crowdsourcing in a social ecosystem, which will allow users to compare and choose between multiple options/services classified by a set of criteria – including environmental impact, travel time, comfort, cost – according to their preferences; this will make the travel experience both more positive for individual users, and globally more sustainable. This framework, consisting in a combined suite of travel offer classifications and software components, will be natively integrated into existing collective and on-demand transport services, connecting and reinforcing mobility offers, especially in rural and low-demand areas, in order to promote the access to high-capacity services (rail, bus and other public transport services), thanks to easy-to-use multimodal and integrated travel planning, booking and payment features. RIDE2RAIL will design, develop and test in real demonstrators a set of software components for the IP4 ecosystem, including advanced Travel Companion features and a crowd-based Transport Service Provider, which will foster the combination of flexible and regular multimodal mobility through an easy personalisation in diverse existing environments, thus facilitating the market uptake. RIDE2RAIL will deliver a set of validated proof of concepts and business cases envisaging future mobility scenarios, where advanced transport solutions will be seamlessly integrated into existing collective transport services (rail and others) in four (4) diverse cities in Europe: Padua, Athens, Brno and Helsinki.
