Norway implements radar-based AID in sub-sea tunnels

Automatic incident detection (AID) manufacturer Navtech Radar has ventured into the tunnels of Norway and has supplied its radar-based ClearWay solution for the sub-sea 4.5 km long Mastrafjord Tunnel and the 5.8 km long tolled Byfjord Tunnel near Stavanger in Norway as part of a recently-completed tunnel refurbishment project.

Automatic incident detection (AID) manufacturer 819 Navtech Radar has ventured into the tunnels of Norway and has supplied its radar-based ClearWay solution for the sub-sea 4.5 km long Mastrafjord Tunnel and the 5.8 km long tolled Byfjord Tunnel near Stavanger in Norway as part of a recently-completed tunnel refurbishment project.

Radar AID was specified by consultants Multiconsult and following a tender process, systems integrator Trafsys was the winning bidder with the ClearWay solution.

Multiconsult senior engineer Lars Martin Rage explains, “One of the key requirements was AID capability in very harsh weather conditions of snow, rain and fog around the tunnel entrances where sunlight can be a problem. We also needed a low-maintenance solution throughout the tunnel with a very low rate of false alarms.”

Dr Stephen Clark, technical director of Navtech Radar says, “The Nordic countries have introduced radar-based technology in a number of schemes. The Mastrafjord and Byfjord tunnels are exciting examples of recent projects that have successfully embraced our technology solution.”

    Earthquake sensors, automatic barriers and real time monitoring systems are all part of a scheme to make a major Seattle traffic artery safer, by taking it underground. Huw Williams reports. Seattle’s metropolitan area of 3.5 million people, like much of the western seaboard of the United States, lies in an earthquake zone. In Seattle’s case, the city and its hinterland sit atop a complex network of interrelated active geological faults capable of severe seismic activity and posing complex considerations fo

    Are pre-launch trials of charging systems the way to improve public acceptance? Or is the real key a more robust political attitude? Here, leading system suppliers discuss the issue. The use of distance-based Road User Charging (RUC) is now well established, at least for heavy goods vehicles on strategic roads. However demand management for all vehicles, whether a distance-based charge or some form of cordon scheme, has yet to make significant progress. This is in spite of the logic and equity of RUC being

  • Norway to renovate 200 tunnels
    August 12, 2013
    The Norwegian Public Roads Administration (Statens Vegvesen) has to renovate 200 tunnels before 1 April 2019 to meet European Union safety requirements for tunnels. Norway’s Tunnel Safety Regulations 2007 apply to tunnels on state roads that are more than 500 metres long, of which Norway has 253. Thirty of these were built after 2007 and comply with the regulations, while only around twenty tunnels built after 2007 have been renovated. The authority will present an action program for the 2014-2017 period
