Three way junction at Dragons Green - geograph.org.uk - 1578998. A three-way junction (or three-way intersection) is a type of road intersection with three arms. A Y junction (or Y intersection) generally has three arms of equal size coming at an acute or obtuse angle to each other; while a T junction (or T intersection) also has three arms, but one of the arms is generally a smaller road ...
One way to classify intersections is by the number of road segments (arms) that are involved. A three-way intersection is a junction between three road segments (arms): a T junction when two arms form one road, or a Y junction, the latter also known as a fork if approached from the stem of the Y. Fork in the road Y-junction
This roadway adds two three-way intersections in addition to the original four-way intersection, moving all left turns (in right-hand traffic countries) or right turns (in left-hand traffic countries) from the main intersection. The design is intended to improve traffic flow by reducing signal timing phases from four to two in the main ...
This is because minor roads usually connect to the outsides of two-way roads. However, on a divided highway, both RIRO and LILO intersections can occur. The remainder of this article refers only to RIRO but applies equally to LILO. A RIRO intersection differs from a 3/4 intersection (right in/right out/left in) and an unrestricted intersection.

Sketch in right-hand traffic layout. A seagull intersection [1] or continuous green T-intersection [2] (also known as a turbo-T [3] (in Florida) or High-T intersection (in Nevada and Utah) [4] [5]) is a type of three-way road intersection, usually used on high traffic volume roads and dual carriageways. This form of intersection is popular in ...
At an uncontrolled T-junction (3-way intersection), right of way rules differ from country to country. In Australia, the United Kingdom, New Zealand [1] and parts of the United States (really just California as is cited), [2] [additional citation(s) needed] traffic on the terminating road must give way (yield) to traffic on the continuing road.
The PSI was developed based on the AASHO Road Test's present serviceability rating (PSR). AASHO Road Test was a set of experiments carried out by the AASHTO from 1956 to 1961. [4] Unlike the PSR, which was a ride quality rating that required a panel of observers to ride in a car over the pavement of interest, the PSI does not require a panel of ...
