Even though the turbo roundabouts have been designed in the Czech Republic since the beginning of this century, until the middle of 2015, there was no national regulation which would describe the way of their construction. As a result of this, there are only 10 turbo-roundabouts with various widths of design elements and different traffic signs in the Czech Republic now. From this number there are some that even cannot be considered a turbo-roundabout. The aim of this paper is to present the results we gained within the research project and to present readers with the approach to the construction of geometry of turbo-roundabouts in the conditions of Czech road network and existing legislation and standards.Â
