Abstract
The main purpose of this study was to identify and analyze the prevailing types of accidents at roundabouts. The relationship was revealed between certain types of accidents, the place of their occurrence, and the configuration of the roundabout. The study analyzed 321 accidents at 19 ring intersections. Four predominant crash types were identified: rear-end collision, collision with vulnerable road users, side swipe collision, and entering circulate collision. The greatest number of accidents occurred at the weaving lane and at the entrances and exits of the roundabout. Dividing the ring intersections into separate sections to determine the location of the accident allows drawing conclusions on the nature of road traffic accidents and the impact of the roundabout design on safety.
Highlights
Roundabout is a type of intersection configuration strongly associated with improved road safety
Roundabouts improve road safety by reducing the number of conflict points and traffic speed, which leads to a decrease in the severity of the consequences of road accidents [8]
The resulting sample of 321 accidents at ring intersections coped with this goal
Summary
Roundabout is a type of intersection configuration strongly associated with improved road safety. International studies of intersections, which were transformed from regular ones to roundabouts, indicate significant reductions in road traffic accidents, especially with serious injuries and fatalities [1,2,3,4,5,6,7]. Roundabouts improve road safety by reducing the number of conflict points and traffic speed, which leads to a decrease in the severity of the consequences of road accidents [8]. A large number of studies are focused on the characteristics of traffic safety at roundabouts, but due to the peculiarities of collecting data on road accidents in the Russian. The prevailing type of accident is determined, which in turn
