About ITS Terminology 2018

This is the fourth edition of the Nordic ITS Terminology. It is financed and published by three Nordic transport administrations, namely the Finnish Transport Agency (Liikennevirasto), the Norwegian Public Roads Administration (Statens vegvesen) and the Swedish Transport Administration (Trafikverket). The Danish Road Directorate (Vejdirektoratet) and the Icelandic Road and Coastal Administration (Vegagerðin) have supported the work by providing national translations.

The terms and definitions are mainly from the road sector but many definitions are generic and multimodal. The basic philosophy behind this Terminology has been to provide definitions for ITS functions or services rather than products or technologies. However, in an effort to make the Terminology more understandable and complete, many generic concepts as well as some technology related terms have been included.
