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.”

    Hitting an animal on a rural road can be fatal for all parties involved – but detecting and avoiding them requires clever technology. Andrew Williams carefully scans the horizon for details. Wildlife-vehicle collisions are an ever-present threat in rural areas around the world, and there is certainly nothing funny about suddenly finding an angry moose in your headlights on a sharp bend. A variety of detection and avoidance systems are currently in use or under development to help prevent your vehicle being

    With the Idris system now validated as a speed verification tool, the way is open for loops to be used in more complex enforcement applications. Diamond Consulting Services (DCS), developer of the Idris inductive loop-based vehicle detection and classification system, has recently successfully conducted validation trials which, the company says, open the way for Idris to be used for speed verification and loop-based sensors to be used for more complex applications such as speed-on-green and differential spe

    Shem Oirere looks at plans to tackle chronic congestion in the Kenyan capital - where commuters can typically expect it to take up to two hours to complete a 15km journey. Traffic jams in the Kenyan capital, Nairobi, are estimated to cost the country $360 million a year in terms of lost man-hours, fuel and pollution. According to Wilfred Oginga, an engineer with the Kenya Urban Roads Authority (KURA), the congestion has been exacerbated by poor regulation and enforcement of traffic rules, absence of
