Abstract

Research conducted in recent decades has shown that there are significant variations in speed at roundabouts depending on the geometric elements. Due to the characteristics of roundabouts and the way vehicles move, there is a reduction in speed, not only in the roundabout zone, but also at the approaches to the roundabout. This paper analyzes the influence of different types of roundabouts as one of the elements of the street system, on speed as one of the basic parameters of traffic flow that defines the functionality and quality of traffic conditions. The research of speeds was done on the approaches to the roundabout, as one of the characteristic segments of the roundabout.
