In 1931, the first edition of the "Technical Dictionary of Road Terms" was published in six languages: Danish, English, French, German, Italian, and Spanish. The World Road Association has continued working on terminology ever since. In 2007, the eighth - and last hard-copy - edition was released in five languages: English, French, German, Portuguese, and Spanish.
The multilingual terminology database can be accessed on-line on the PIARC website for specific term and/or per theme searching, and the search results can be displayed simultaneously in three languages.
The multilingual terminology database of the World Road Association has been created by merging the Technical Dictionary of Road Terms, the Lexicon of Road and Traffic Engineering, and a number of specialized dictionaries in the field of roads and road transport. It will, henceforth, be on-line as a single "PIARC Road Dictionary".
The Committee on Terminology is reponsible for updating and upgrading this Road Dictionary,with inputs from the experts in the Technical Committees and with the help of National Committees and member countries for translations into other languages than English and French.
