The programme has lasted from 2005 to 2010 and has comprised: 1) statistical analyses of involvement in fatal crashes, 2) a comprehensive survey among crash-involved drivers regarding mobile telephone use and other distractions, sleepiness, health problems, and medicine consumption, 3) analyses of reports from the crash investigation teams of the Norwegian Public Roads Administration, and 4) estimation of contributions of different risk factors to total number of road crashes. The factors that contribute most to the number of serious crashes are speeding, vulnerable road users, non-use of seatbelts, young male car drivers, heavy vehicles, driving under the influence, illness, and age over 75 years. There are substantial contributions from several additional factors, e.g., distraction and sleepiness. (Author/publisher)
