ARCADY (Assessment of Roundabout Capacity And DelaY) models traffic capacity, queues, and delays at roundabouts. [2] The software is largely based on empirical relationships between roundabout geometry and capacity, which were established as the result of extensive research carried out on existing roundabouts on the UK road network, as well as ...
State Route 620 in Fairfax and Loudoun Counties, Virginia is a secondary state highway.The entire length of SR 620 is also known as Braddock Road (except for a small section in Centreville called Spindle Court).

[6] [7] The second roundabout would be at the intersection of SR 20 and US 33 just south of Barboursville. This project might also include reconstruction of the ...
A design memorandum was produced in 2003, followed by full construction design documents. Project construction began in 2007, with various elements of the project completed and some underway. "Lessons Learned "Roundabouts were used to address traffic congestion and safety at key intersections such as Route 50 and Route 15 at Gilberts Corner.
In 2003, Virginia Department of Transportation Commissioner Philip A. Shucet stated that "[s]ingle drivers could pay $1 to $4 to get off of the congested regular lanes."

A three-level diamond interchange is a type of highway interchange where through traffic on both main roads is grade-separated from intersections which handle transferring traffic. [1] It is similar in design to a three-level stacked roundabout except for its use of (usually signalled) conventional intersections, and can be thought of as two ...
