The contribution presents the main principles of roundabout safety layout. It is result of the research project for the Ministry of Transport of Czech Republic No. CG911-008-910. The name of the project is Influence of structural elements geometry on safety and fluency of operation on roundabouts and possibility of rise crashes prediction. The research includes a large set of roundabouts based on the analysis accident rates in proportion to the traffic flow. The comparison of the geometry and relative accident rates resulted in recommendations for the design of roundabouts. In this article the attention is paid to the most important factors affecting safety at the roundabouts.
