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.

In August 2017, the US Federal Highway Administration (FHWA) issued the first results from an upgraded version of its National Performance Management Research Data Set (NPMRDS). Developed to identify the locations and times of high congestion affecting traffic flows along America’s 259,000km (161,000 mile) national highway system, this is a key resource for sta

    Bob Lees, co-founder of Diamond Consulting Services, on why the loop detector just refuses to go away. The more strident proponents of newer and emergent detection technologies are quick to highlight what they see as the disadvantages, and hence the imminent passing, of the humble inductive loop. The more prosaic will acknowledge that loops continue to have a part to play in traffic management, falling back on the assertion that it is all a question of application. And yet year after year the loop, despite
