Abstract:
This paper shows the first knowledge of operation of the turbo-roundabout
in the Czech Republic. It shows the main characteristics of this new type of roundabout and wants to
compare the differences between turbo-roundabouts in the Czech Republic and in the Netherlands
as a mother-land of turbo-roundabouts. The article provides the reader with all known types of
turbo-roundabouts, designs, used traffic signs and markings, and comparison of the capacity. The
main goal is to emphasize mistakes in the Czech Republic and to show the correct solution for planning turbo-roundabouts to get safety intersection with enough capacity. Analysis shows that there
are formed fairly large plugs at following vehicles in both directions at peak periods. Therefore, the
authors of this paper proposed a scheme of multilevel road interchange, eliminating conflict points
that increase capacity of interchange and ensure the safety of pedestrians.
