Based on a previous research (VSS 2011/202 "Base project for the design of road crossings for multiple road users"), normative deficits in the design of intersections were highlighted. The research VSS 2015/221 "Crossroad's research package: Package lead and standard bases" defined a new normative framework for intersection (planning basis, design basis, design standards).
The current research aims to establish the normative content of design standards for roundabouts according to the newly established framework while addressing the identified normative deficits.
