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

A new version of the DG QRAM software (Quantitative Risk Assessment Model for the Transport of Dangerous Goods in Road Tunnels) has just been published. This PIARC software is currently under development and a new update has been released.

The official program is distinctive in the way it highlights the many connections between the world of tunnelling and the disciplines that until now have been considered unrelated to the field. A special Triple-A sessions - Archaeology, Architecture and Art are examples of such topic, and is followed up with a special visit to see the Tunnel Borbonico, the ancient underground tunnel commissioned in 1853 and just recently restored.

This conference focused on tunnels as a vital links in any transportation network. Short periods of closure for maintenance or repairs always generate nuisance. Long periods of closure for renovations will logically lead to severe congestions. For too long, the tunnel community has accepted this nuisance and chaos as a natural side effect of tunnel operations. Should we accept this?  

New energy carriers (also known as NEC) for road transport, such as battery electric cars, and fuel cell cars, entail new risks for the safety of tunnels and underground parking lots.

The world is facing a huge energy challenge. Fossil fuels are 'out-dated‘ and sustainable alternatives are the unquestionable future. This will be the topic of the ITA-COSUF workshop on New Energy Carrier Vehicles in underground transportation facilities on the 21st of February 2019.

We where invited to witness a full scale low pressure water-mist fire test in the well-known Applus+ "San Pedro de Anes" Experimental Centre, last week. The host of the event was VID Fire Kill ApS, a danish based Low Pressure Watermist manufacturer. 

Lund University and SINTEF independent research organisation, are conducting a survey in which they seek attendees. In the experiment, the subjects will move in a computer-generated environment and the study is investigating human behaviour in a road tunnel where different incidents can occur. 

An important part of upgrades and rehabilitation of tunnels is to protect side area that represent a risk for collisions. The new SMA crash cushions from Automation Manufacturing Services ltd. prove that it is possible to produce space-saving solutions that are easy to install, reliable over time, maintenance friendly and provide a high degree of safety. 

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.

The peak organisation of Australasian road transport and traffic agencies, Austroads, identifies factors that contribute to the occurrence and severity of collisions adjacent to and within tunnels and suggests remedial treatments. The objectives of this study were to identify factors that contribute to the occurrence and severity of collisions adjacent to and within tunnels and remedial treatments that will reduce the incidence and severity of these collisions.
