This thesis builds on previous work on an Institute of Roads FAST VUT dealing with modifications of road I/43 Brno – Svitavy. A conversion of the existing temporary three leg single lane roundabout to egg turbo roundabout with four legs, is proposed there, in accordance with local plan of Lipůvka. The intersection of road I/43 and II/379 can be characterized by large congestions in the morning peak hours during weekdays and afternoon peak hours on Saturday and Sunday. That is the reason for implementation of capacity assessment of designed turbo roundabout and comparison with current situation. Construction of fourth leg is motivated by the planned expansion of residential area and the development of industrial zone on the south-western outskirts of the village and rerouting of the county road II/379 out of built-up area as well. Road I/43 is an important thoroughfare north of Brno, so it is obvious effort to eliminate the bottlenecks on the route.
The thesis also includes a theoretical introduction dealing with the design of turbo roundabouts abroad.
