Abstract
Historically, there are several large roundabouts in Vilnius with traffic organisation and safety problems. Vilnius City Administration initiated changes on these large roundabouts in 2016, by introducing new traffic organisation schemes and using relatively simple measures such as the line markings, safety measures and road signs. The aim of the research is to analyse the number of traffic accidents on the roundabouts before and after such traffic reorganisation. The article is based on accident maps in roundabouts created by the authors. Based on the comparison of accident maps, the safety trends were analysed and summarised.
Highlights
Vilnius is the capital and the largest city of Lithuania, where the country’s most important political, social, cultural and economic institutions operate
The aim is associated with the tested hypothesis, i.e., whether better traffic organisation schemes might ensure better traffic safety in large roundabout systems
Major issues before the transport organisation changes in 2016. This roundabout system is a very important element for Vilnius transport system as it connects the central part of the city with Šnipiškės, Žirmūnai and Antakalnis districts, and it is essential for those arriving from Naujoji Vilnia and Markučiai districts
Summary
Vilnius is the capital and the largest city of Lithuania, where the country’s most important political, social, cultural and economic institutions operate. It should be noted that large roundabouts are problematic from the point of view of traffic safety in other larger cities of Lithuania, i.e., Kaunas or Klaipėda (Dumbliauskas, Grigonis, & Barauskas, 2014; Sivilevičius, Paliulis, Klibavičius, & Palevičius, 2015). The primary aim of this comparative research is to evaluate the number of traffic accidents on the roundabouts before and after traffic reorganisation (6 August 2016) on a practical level. The aim is associated with the tested hypothesis, i.e., whether better traffic organisation schemes might ensure better traffic safety in large roundabout systems. To verify the hypothesis whether traffic organisation schemes might ensure better traffic safety in large roundabouts;.
