The aim of this bachelor thesis is a change of the existing crossroad in Svoboda Square in Ústí nad Orlicí. The current state of the crossroad is inconvenient from a traffic safety point of view. It is problematic when the cars turn into 17 Listopadu Street from Tvardkova Street and hinder the cars going into Tvardkova Street from Letohradská Street. Furthermore, the location of the bus station is inappropriate and pedestrians who cross the street are in danger. The content of this thesis is to propose improvements of clarity by the construction of the roundabout.
