Lithuanian experience of implementation of roundabouts: the research of accidents, operation and efficiency

Abstract

In the past decade, Lithuania had one of the worst statistics in road traffic safety in comparison to other European Union countries. The implementation of roundabouts in most dangerous intersections was a key element that brought about many promising and positive results in this field. Since 1998, when the first modern roundabout was built in Lithuania, around 40 more of these engineering structures have been constructed. Although it has been justified as a safe solution; there is still considerable scope for improvement. For this reason the data of accidents, design mistakes, construction flaws and operation problems have been researched and collected. This article concentrates on improving characteristics of roundabouts, making them more adequate for Lithuanian weather conditions and driving mentality.
