Roundabouts (traffic circles) have become a commonly used solution for intersections in The Netherlands. The popularity of the roundabout is largely due to its effect in greatly reducing the incidence of (serious) road accidents and in having a relatively high traffic capacity compared to more traditional types of intersection and traffic control installation. Presently between 50 and 60 roundabouts are constructed in The Netherlands each year. Roundabouts have considerable impact on road safety. Where intersections have been converted into roundabouts, the total number of registered accidents have been reduced by almost 50%. In fact, the number of casualties was reduced by about 70%. Besides this it appears that the reduction in the number of casualties among cyclists and moped riders was less notable than among car occupants: being 30% and 63% for cyclists and moped riders respectively and 95% for car occupants. The reduction in casualties at locations outside built-up areas proved to be greater than at locations within built-up areas (a reduction of 86% and 69% respectively). On the basis of accident analyses it is recommended that a separate lying cycle-track is preferable for application on roundabouts with a capacity of approximately 8,000 motor vehicles per 24 hour period and a significant volume of bicycle traffic.
