Feasibility design of the R2-411 segment by constructiong a modified intersection and a roundabout in Naklo

摘要

This dissertation presents a section of a regional road R2-411 in Naklo, Slovenia. It is focused on a four way intersection near a gas station, for which there have been, according to regulations, discovered some deficiencies and irregularities. Attention is also drawn at the intersection’s points of conflict and potential dangers, since the intersection itself deviates from prevailing principles of intersection design. The first part of dissertation addresses technical norms of intersection design followed by the anaslysis of the actual state of the selected intersection and a presentation of traffic flow. The second part focuses on technical requirements for implementation of a roundabout. The first possible theoretical solution of the existing state of the intersection is a modified intersection with no traffic lights, and the second one is rearrangement of the existing four way intersection into a roundabout. Both solutions are also presented graphically. Design is based on the technical specifications for road works.
