The present fourth edition is the result of continuing valuable cooperation between three organisations (Eurostat, UNECE and ITF), 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. The Glossary now comprises 735 definitions and represents a point of reference for all those involved in transport statistics. 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.
