STUDIES ON TRAFFIC ACCIDENTS IN NORWEGIAN ROAD TUNNELS

As Norway has nearly 900 road tunnels on its national and county roads, it is necessary to study tunnel accidents and incidents. The safety of Norwegian tunnels has been debated in the media. This paper presents a study of personal injury road tunnel accidents by the Norwegian Public Roads Administration (NPRA), using road data from its National Road Data Bank and accident data from police reports. The study results showed that road tunnels in Norway are as safe as high-standard modern roads. The accident rates were highest in entrance zones, and accident severity was higher on tunnels than on open roads. The results are based on data from 587 road tunnels, most of which opened in 1992 or earlier. No injury accidents were reported during a five-year period for 388 of these tunnels. The study covered all tunnels, including those without accidents. In the 499 injury accidents reported, there were 26 fatalities, 99 people seriously injured, and 620 people slightly injured. The paper includes many statistical tables and charts, and details results on: (1) accident severity; (2) accidents in tunnel zones; (3) accident types; (4) accidents in relation to tunnel lengths; (5) accidents and traffic intensity; (6) accidents and lane widths; (7) accidents in different weather and road conditions; (8) light conditions; (9) accidents in undersea tunnels; and (10) accidents in dual-tube tunnels.
