abstract="Flare and taper of modern roundabouts create a high capacity where it is needed, at ramp and frontage road intersections. Entries to roundabouts are flared to add lanes and exits from roundabouts are tapered to drop lanes. Thus the capacity of large roundabouts nearly equals the capacity of narrow link roads joining them. Unlike interchanges regulated by traffic signals, modern roundabout interchanges do not require long storage and turning lanes over or under the most expensive element of the interchange, the bridge.   <p>Language: en</p>",
