In my bachelor thesis, I focus on the traffic situation in the city of Blansko. I managed to get a construction study of an interchange with a railway which I accept, and I carry on with a traffic research on the railroad crossing and an adjacent roundabout. The aim of this thesis is to suggest short-term solutions to the current situation and to compare present and prospective state with regard to the construction of an overpass which is going to be the first interchange linking two parts of the city.
