The rapid growth of VMS density and coverage on the TEN-T Roads has led to the use of VMS in local ‘language’ and non-standard signalling. It is important to avoid a situation where the European traveller may not be able to understand information directly concerning his/her safety and mobility while driving because of language problems. A real, complete, harmonisation of VMS will improve safety and increase the efficiency of the road network, in particular for long distance
transport. This is the main objective of the VMS-Mare Nostrum, that works to identify and develop specific informative elements (pictogram, alphanumeric codes) and message structures which are independent from local languages. Mare Nostrum work is currently focused on the short, middle and long term improvement of the related Deployment Guidelines.
Long term improvement of the DG is expected by VMS-Mare Nostrum because the group is working in parallel to ensure that VMS recommendations reach UNECE level. This means that we are promoting a top-down and endurable harmonisation flow for a better understanding of VMS.
