Road tunnel operations

Since 1957, date of creation by PIARC of the "Committee on Road Tunnels", the Association has conducted an ongoing activity on all matters relating to the operation of road tunnels: geometry, equipment and maintenance, operating, safety and environment.

The results of the committee's work were first published as:

  • monographs on the occasion of the World Road Congresses, starting from 1959 (Rio de Janeiro Congress);
  • then in the form of thematic reports from 1995 that can be found in the Directory of Technical reports.

Knowledge is, since 2011, structured in an electronic form: the Manual of Road Tunnels, which presents various topics related to the operation of road tunnels and links to the various publications in this field.
