The Committee on Terminology (CTERM) regularly updates these dictionaries, in particular

  • the Technical Dictionary of Road Terms (PIARC Dictionary) and
  • the PIARC Lexicon of Road and Traffic Engineering (PIARC Lexicon).

At the time of the start-up of this software on Internet (end of 2004), the base contained approximately 23,000 terms in English, 20,000 in French, and a variable number of terms in other languages (Danish, Dutch, Finnish, German, Hungarian, Italian, Japanese, Norwegian, Portuguese, Russian, Spanish, and Swedish).

Serbian and Vietnamese were added to the PIARC Dictionary in 2005, Norwegian and Ukrainian in 2007, and Estonian in 2011.

Dutch is continuously updated.

German and Portuguese were updated in 2007, and Spanish and Czech in 2011.
