N2  - Roundabouts have been a popular system for intersections outside down-town zones in urban areas in Switzerland for more than 10 years. One form of small roundabout becoming more common in Switzerland is the system with short two-lane approaches and a single-lane extrawide circulatory roadway. Research shows that small roundabouts with two-lane entries with a single-lane extrawide circulatory roadway have capacities 20% to 30% higher than those with single-lane entries, although the space requirements are almost identical. The fact that roundabouts with two-lane entries and a single-lane extrawide circulatory roadway have shown good performance with respect to capacity, traffic flow, and driver behavior, as well as a high level of safety, has led to an increasing use of this type of roundabout in Switzerland.     <p>Language: en</p>
