The one-lane roundabout is designed at the crossing point of road II. Class (Ob-vodová) and local road (speed-A, Přístaviště) in Brno. The current state is unsatis-factory. The danger is at risk due to the increased maximum permitted speed before the junction and also because of the MHD JMK bus stops, which are cur-rently solved in the form of a lane stop in the local road, or with partial bus bay. The goal of this bachelor thesis is to maximize the safety of traffic participants. Furthermore, emphasis is placed on minimizing interference with existing struc-tures, the environment and aesthetics.
