The European University Institute (EUI) has published a new policy brief discussing a common European mobility data space. The European strategy for data aims to establish a single market for data, where data can be accessed and used efficiently. This will include the creation of a common European mobility data space to facilitate access, and sharing of transport and mobility data. Against this development, the 10th Florence Intermodal Forum brought together relevant stakeholders to discuss opportunities and challenges for building such a mobility data space and published the views in a policy brief.
