This report discusses a number of topical subjects involving the use and realisation of roundabouts. Sparking the report was the need to include these roundabouts in a system of `sustainably safe' infrastructure in the Netherlands whilst taking the required consistency in right-of-way regulations and layout into consideration. The results of this study should also form a basis for the new publication about roundabouts being prepared by a study group in the Netherlands Centre for Research and Contract Standardisation in Civil and Traffic Engineering (CROW). The first subject concerns regulating the right-of-way at older roundabouts where the `traffic from the right has priority' regulation is still being applied, this regulation being unlike the regulation applied to the newer roundabouts. The next part of the report discusses the right-of-way regulation and the layout of roundabouts with separate cycle tracks. The study also examined the degree of discomfort experienced by cyclists in having to lend the right-of-way to motorised traffic when crossing the carriageway. The last part of the report concerns a study into the capacity and safety of two-lane roundabouts. (A) See also C 4196 (IRRD 877165).
