abstract="Recently, many of the foreign traffic-safety analyses point out the low level of traffic safety in multi-lane roundabouts. This problem is resolved in several ways in different countries; however, the solution, whereby the number of conflict points is diminished (e.g. turbo roundabout) has proven to be the most successful. However, the turbo roundabout also has its deficiencies: it has conflict crossing points and larger reconstruction of the existing two-lane roundabout is needed when the turbo roundabout is to be implemented instead of the existing one. In the paper a new type of roundabout has been introduced; the roundabout with &quot;depressed&quot; lanes for right turning (&quot;the flower-roundabout&quot;). Financially speaking, the main advantage of the new type of roundabout is that it can be implemented within the dimensions of the already existing &quot;normal&quot; two-lane roundabout. From the traffic-safety point of view, the main advantage of the new type of roundabout is that it has no crossing conflict points.KEYWORDS: traffic safety, roundabout, turbo roundabout, roundabout with &quot;depressed&quot; lanes for right turn<p />",
