The NOESIS project aims to develop a decision support tool for evaluating big data investments in transport, focusing on their socioeconomic impacts and associated risks. It addresses the absence of a robust methodology for assessing the value generated by big data applications, producing a framework that includes a library of use cases, impact assessment methodologies, and business model definitions. The initiative seeks to provide evidence-based decision-making tools for policymakers and improve the successful implementation of big data technologies in the transport sector.
