Abstract

During the last decade roundabouts served the purpose to be the one of the safest and to have the highest capacity of all at-grade intersections. Unfortunately, until now Lithuania had no detail design standards adapted specially for roundabouts, moreover, there was no clear vision what construction and design principles should be used for roundabouts. This article presents analysis of roundabout design and construction methods in Lithuania. Methodical Guidelines for the Design of Roundabouts proposes how to classify roundabouts into five different types. Also, it proposes the main principles and guidelines for roundabout design adapted for the use in Lithuania.
