My thesis covers the existing intersection on the main road R2 413 Zbilje-Vodice in the Valburga settlement near Medvode. Initially I describe the current state of the intersection, its location, problematic issues of the current state and reasons for a reconstruction. Secondly, I present the traffic loads, acquired by the means of a traffic count and analysis of its results. The third chapter covers the rearrangement of the intersection into a roundabout, with special emphasis on theoretical insight into roundabouts, the spatial insertion of the roundabout into the existing intersection, defining the technical elements of the roundabout, conducting permeability control as well as tractrix and visibility control. Then I present a second option of reconstruction where I add special lanes for left turning vehicles. As with the roundabout I equip this reconstruction also with a theoretical insight, background of technical element definition, permeability and tractrix control. Finally, I conclude my thesis by choosing the better of the two options.
