The Armdale rotary
NS) demonstrate the subtleties of U.K. design based on research of
capacity and safety relationships to six geometric design elements.
Capacity was added to this five leg rotary that operates with >5,000
vehicles per hour such that long am and pm queues were reduced
considerably without changing the number of lanes of all but one entry.
Safety performance was also improved with the combination of geometry,
sophisticated pavement stripes, pavement arrows and navigation signs. ORC
and ORE are involved in several of this kind of rehabilitation projects
throughout North America.
