The Glossary is the result of continuing valuable co-operation between these three organisations that – through the action of the Intersecretariat Working Group (IWG.Trans) – have put a sustained effort into meeting the need to harmonise transport statistics at the international level. By following the guidance contained within these definitions, a considerable contribution will be given to the improvement in both the quality and comparability of the data
The present fourth edition of the Glossary is an illustrated version, it includes 7 transport themes (rail, road, inland waterway, pipelines, maritime, aviation and intermodal transport) and comprises 735 definitions. It represents a point of reference for all those involved in transport statistics.
