THE INFLUENCE OF GEOMETRIC ELEMENTS ON THE SERVICE LEVEL AT ROUNDABOUTS

The service level is the quality of traffic conditions in the road network, which includes comfort, safety, freedom of maneuvering and so on. There are different service level depending on the conditions and circumstances of the roundabout construction. The purpose of this paper is to highlight the geometric elements as highly important parameters in the uninterrupted traffic flow in roundabouts, as well as the safety elements for an uninterrupted and efficient traffic flow.
