Identification of high accident concentration sections on the Lithuanian roads of national significance

Abstract

In recent years, safety improvement measures on the roads of Lithuania have been implemented mainly at the pre-determined black spots. Although the road safety situation since 2008 has improved and the number of black spots is decreasing year by year, most of the identified black spots are formed once again. Seeking for accident prevention and not waiting until accidents occur and the black spot is formed, it is necessary to use accident prediction models and to implement safety improvement measures on the potentially dangerous road sections, thus, preventing the formation of new high accident concentration sections. The paper describes how to identify high accident concentration sections on roads using accident prediction models and the critical value of predicted accidents. All high accident concentration sections on Lithuanian roads of national significance were studied during the research. The list of the most hazardous road sections is given in this paper.
