The MERIDIAN project will foster digitalisation of the mobility system focussing mainly on the CEF Core Network Corridors Scandinavian-Mediterranean and North Sea-Baltic. This will be achieved by implementing digital systems and services along the busiest European freight corridors. The project will further target expansion of digital infrastructure, roll-out of C-ITS in central Europe, implementation of ITS for bottlenecks on open road and tunnels, digital corridor management and Multimodal Services. Its implementations will support common objectives to increase traffic safety and reduce congestion.
