During the 2008-2011 cycle, the Road Tunnels committee reviewed all the terms and definitions relating to road tunnels which existed in the various PIARC dictionaries, in particular the PIARC Dictionary (Theme1 5: Tunnels) and the PIARC Lexicon (Theme 6: Bridges and Tunnels). From all these terms, it retained a first list of 140 terms. These terms and their definitions were reviewed and validated in French and English. This list of terms served as first version for a new specific PIARC dictionary: the "Road tunnel operations" dictionary.
This list of 140 terms and definitions was then translated by the committee members in 17 different languages among those which are used by the Terminology Committee.
The list of all these terms and their definitions are available on the PIARC Web site, at the heading "Search per theme" in the page "Terminology", while clicking on "Road tunnel operations" in the list of the dictionaries and while clicking then on "Road tunnel operations" in the list of themes.
This list is also available in an Excel file which will give all the terms and all their definitions in the 19 languages as their availability. This list is available under two forms:
