The data volumes produced in secure and trustworthy digital infrastructures are huge. But they are meaningless without efficient data governance. Thus, the exploitation of mobility data (urban and maritime domains) has wide potential due to the emerging applications and the environmental footprint. In this context, the EU-funded MobiSpaces will develop an end-to-end mobility-aware and mobility-optimised data governance platform with key differentiating factors. Specifically, it will design the extraction of actionable insights from ubiquitous mobile sensor data and IoT devices in a decentralised way. Five mobility use cases – from smart public transport services in cities to vessel tracking – will demonstrate the impact of the project’s platform in real-life scenarios.
