The background for this study was a discussion on how the potential of ITS services and in particular C-ITS based services could be facilitated from a transport system perspective. It was noted that deployment of ITS in general have had a fragmented approach with a focus on roadside equipment and specific services. In addition, ITS services have to a large extent been oriented towards transport of people. Furthermore, there need to be a focus on corridors since the backbone of the European transport system are the nine Core Network Corridors for road and rail transport. This led to the overarching question, how can ITS services contribute to a more efficient usage of the transport system with a focus on freight transport from a corridor perspective?
