Editing Intersection (road) (section)

=== Road segments ===
One way to classify intersections is by the number of road segments (arms) that are involved.
* A [[three-way junction|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.

* A four-way intersection, or '''crossroads''', usually involves a crossing over of two streets or roads. In areas where there are [[city block|blocks]] and in some other cases, the crossing streets or roads are [[perpendicular]] to each other. However, two roads may cross at a different angle. In a few cases, the junction of two road segments may be offset from each when reaching an intersection, even though both ends may be considered the same street.
* Six-way intersections usually involve a crossing of three streets at one junction; for example, a crossing of two perpendicular streets and a diagonal street is a rather common type of 6-way intersection.
* Five, seven or more approaches to a single intersection, such as at [[Seven Dials, London]], are not common.
