Vortragsfolien Radverkehr Scroll to the section labelled "Kreisverkehr". A translation of the text reads: Graphic from Sicherung von Radfahrern an städtischen Knotenpunkten [Safeguarding cyclists in Urban Intersections], (BASt, 1992). Accident numbers in large circular junctions with different bicycle facilities show: 1. Why there should be no pathways or bike lanes at these junctions; 2. Even when cyclists use the roadway, their risk is relatively high at these junctions.
