The multilingual Terminology database of the World Road Association comprises 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.
In 1931, the first edition of the "Road Dictionary" 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 eight edition was released in five languages (English, French, German, Portuguese, and Spanish).
The multilingual terminology database can be accessed on-line for making term searches and searches per theme, and the results can be displayed simultaneously in three languages.
