Safety issue for Swedish tunnel

Safety concerns have been raised over air pollution levels in Stockholm's 18km tunnel bypass. Data from the Swedish Transport Agency (Trafikverket) suggests that pollution in the Stockholm Bypass project (Förbifart Stockholm) could result in 20-30 fatalities/year due to the increased risk of triggering serious breathing disorders. The data suggests that high levels of dangerous particulate matter could pose a serious risk to users of the tunnel at peak periods. The new road will be paved with concrete rathe

Safety concerns have been raised over air pollution levels in Stockholm’s 18km tunnel bypass. Data from the 2124 Swedish Transport Agency (Trafikverket) suggests that pollution in the Stockholm Bypass project (Förbifart Stockholm) could result in 20-30 fatalities/year due to the increased risk of triggering serious breathing disorders. The data suggests that high levels of dangerous particulate matter could pose a serious risk to users of the tunnel at peak periods. The new road will be paved with concrete rather than asphalt, and dust extraction systems, increased ventilation and particle filters should be installed to improve air quality in the tunnels according to Trafikverket. Other benefits could come from cutting the use of studded tyres by 25% and lowering the speed limit to 70km/h during the winter period.

    An innovative project at a busy UK retail park could provide the blueprint for a new approach to pedestrian safety, according to its developers. The system utilised hard-wired active flashing LED road studs from Rennicks UK to delineate the crossing, in conjunction with LED warning signs from Swarco. Pole-mounted C-Walk pedestrian detectors from Flir activate the high performance LED studs to create a striking visual warning for motorists approaching an internal crossing at Giltbrook, near Nottingham.

The seven corridors included a total of 223 signalised intersections. To conduct this study, termed the Traffic Signal Optimisation Study for the Metro Nashville Signal System, MPW received funding from the Federal Conge
