The main purpose of the is to advance the role of public transportation systems through an open platform capable of combining Interoperable Fare Management (IFM) and Intelligent TransportSystems (ITS). The overall platform is intended to be user oriented and user centric, in a way thatwill foster and promote user awareness and consciousness about public transports and eco-mobility, other than providing for a significant mix of services including info-mobility, trip planning, ticketreservation, fare calculation and mobile payments.The fruition model of the HoPE platform will be primarily based upon mobile devices and is intended to complement and enhance pre-existing information and payment systems by adding useful forecasts about partial/overall journey time and partial/overall greenhouse gas emissions (in addition to fare calculation and mobile payments).Smart Ticketing features will implement secure payment procedures exploiting different technologies (NFC, QR codes, etc.) and will seamlessly support the entire buying process, as wellas the ticket validation. This will lead to a flexible and advanced framework in which several transport operators will be able to join the system by adhering to a set of technical specifications and without undergoing long and complex administrative processes or strict legal agreements.Smart Trip-Planning features will provide for an unprecedented, reliable, and comprehensive user experience, always proposing to travelers the best available options for the next part of their journey, enhancing one or more key metrics associated to their trip (fare, duration, emissions). This will be obtained exploiting static and real-time information used by several optimization engines to enforce customizable policies and strategies.The HoPE platform will be piloted and tested at three European cities and will be applied to a wide set of local and regional transport means (buses, undergrounds, railway lines, car-sharing, bike sharing, etc.).
