The number of intersecting legs, or the number of roads that will join to form an intersection, determines the type of intersection. The basic intersection types are three-leg, four-leg, multileg, and roundabouts. An example of a three-legged intersection is a T-type intersection, which is used to terminate one road. Four-legged intersections are crossroads where two roads meet, usually at a right angle. Try to avoid skewed intersections because they create problems with visibility, turning angles, and pedestrian crossings. Where skewed intersections must be used, the skew should be no more than 30 degrees off perpendicular; otherwise realign the roadway s to form a perpendicular intersection.
