In Sweden the most common type of road traffic accidents involving passenger cars are single accidents (where only one vehicle is involved). The aim of this thesis is to analyse how these accidents occur, and present recommendations on how to reduce the number of deaths. Data has been collected from the Swedish Transport Administration’s in-depth studies of fatal accidents. Road traffic accidents with fatal outcome that happened on public roads during the years 2007 to 2009 have been studied. Some of the most important results of the study are: Most single road traffic accidents with fatal outcome happen during the weekend and most commonly during the evening or the night. A majority of the drivers are male and many are young. About 50 percent of the deceased did not use seat belt. Older cars are over-represented in these accidents when compared to their vehicle mileage on the Swedish roads. Half of the deceased people could have survived if all drivers were sober. One third could have survived if all roads had rumble strips. Half of the deceased might have survived in cars with electronic stability control system. 90 percent of the deceased people could have survived in cars equipped with the latest safety technology. The results in this thesis are discussed in the theoretical context of resilience engineering. The in-depth studies of road traffic accidents with fatal outcome in Sweden are positive for the traffic safety but there is room for improvement.
