Road Charging Interoperability. This project is financed by the European Commission and it proposes to make possible to carry out any road charging transaction in Europe with a single in-vehicle equipment. The RCI project will develop an open, integrated framework enabling road charging interoperability at the technical level based on the key existing and planned road charging deployments in Europe (AUTOPASS, EUROPASS, LSVA, TELEPASS, TIS, TOLLCOLLECT, VIA-T and VIA VERDE).
