In this thesis I deal with an intersection between Ižanska road, Peruzzijeva street and Črna vas. Although this intersection is signalized, I will deal with it as if it is an unsignalized intersection. First I describe the current situation, and give reasons for its improvement. I calculated the permeability of intersection with the help of traffic loads data, that I got by traffic count. I decided to design two different solutions. The first solution would be, to reconstruct the geometry of existing intersection, and the second one would be to place a new roundabout. For both solutions I define and explain the elements that I used for their geometry. I check the permeability and the overview of the junction. I also list used road and vertical traffic equipment. At the end I assess which solution is more suitable and if there might be another, better solution.
