Abstract: The article addresses the issue of converting existing conventional multilane roundabout to a look-a-like turbine traffic roundabout. A case has been proposed by reviewing different solutions of traffic control devices on existing conventional multilane roundabouts with a circular central island. Four different variants of traffic control devices has been presented, which take into consideration the availability of land and analysis of projected traffic volumes at individual entrances and routes. In addition, three Szczecin multilane roundabouts were characterized, where the existing traffic control devices was changed in 2019 and a look-a-like traffic roundabout was introduced. The roundabouts has been changed by introducing only horizontal markings without any reconstruction of the existing entrances. An analysis of the state of traffic safety was carried out for these traffic roundabouts, confirming that significant improvements have been achieved.
