CORE is a research project co-funded by the European Commission under the 7th Framework Programme. CORE analyses the aspects related to the use of advanced technologies for the freight transport and the logistics, to enhance the visibility and improve the security. The project implements various pilot demonstrations to prove and make concrete verifications in real use cases and along European and intercontinental logistic chains. One of the CORE’s pilot demonstrations concerns a solution integrating GNSS (Global Navigation Satellite Systems) technologies for tracking & tracing the intermodal transport of chemicals and gas throughout road-rail paths across Europe. The developed solution is operated in real business cases/operations and evaluated through KPIs (Key Performance Indicators). In this paper, first an overview of the role of GNSS technology for tracking & tracing the transport of dangerous goods is given, then the CORE solution and demonstration, and the KPIs for the relevant evaluation and assessment, are presented.
