ACEA Position Paper highlights the importance of a diverse range of mobility options to meet different needs, including private cars, shared vehicles, buses, commercial vehicles, walking, bicycles, mopeds, scooters, trams, and metros. Sustainable mobility is defined as achieving efficiency objectives in economic, environmental, and social aspects, with all modes needing to be used efficiently and integrated within a connected network. Cities' action plans for Intelligent Transport Systems (ITS) should address issues related to business models, particularly for promoting public transport and public incentives for new mobility services that complement public transport. Public policies should encourage traditional public mobility operators to embrace innovation in mobility and ensure a level playing field for private providers of shared mobility. New types of shared mobility services with cleaner technologies offer clear benefits, including access to inclusive mobility with lower emissions, reduced traffic volumes, and less need for public space. However, a sufficient charging and refuelling infrastructure is required for zero-emission vehicles to be rolled out across Europe. To make shared mobility systems profitable over time, the positive externalities of mobility systems must be shared between providers, users, and territories.
