 Road tunnels and technology in an operational perspective
Arild Petter Sovik, Tunntech Global News

Experts from businesses and public bodies from all over the world use the well-known Hagerbach Test Gallery in Switzerland to perform research, development, testing and full-scale experiments. The VersuchsStollen Hagerbach AG facilitate cooperation between companies, associations and research institutes, to improve construction, operation and safety of tunnels with a professional approach.

In desember 2017, I visited the International Fire Academy in Balsthal, Switzerland. A special designed tunnel fire training facility, where fire fighters from all over Europe train basic skills for rescue and fire fighting in tunnels. The purpose for the technical visit was to study best practice, an important input to an ongoing study in Norway. 

In the last 3 years 20 tunnels have been installed with acoustic tunnel monitoring detection in Austria. The first pilot where carried out int the 2,4 km long twin tube Kirchdorf tunnel, and the pilot started in 2010.
