=== Lane design === * A [[Roundabout|traffic circle]] is a type of intersection at which traffic streams are directed around a circle. Types of traffic circles include [[roundabout]]s, "mini-roundabouts", "rotaries", "STOP"-controlled circles, and signal-controlled circles. Some people consider roundabouts to be a distinct type of intersection from traffic circles (with the distinction based on certain differences in size and engineering). * A [[box junction]] can be added to an intersection, generally prohibiting entry to the intersection unless the exit is clear. * Some (unconventional or alternative) intersections employ indirect left turns to increase capacity and reduce delays. The [[Michigan left]] combines a right turn and a U-turn. [[Jughandle]] lefts diverge to the right, then curve to the left, converting a left turn to a crossing maneuver, similar to [[Roundabout#Hamburger roundabout|throughabouts]]. These techniques are generally used in conjunction with signal-controlled intersections, although they may also be used at stop-controlled intersections.<ref>Steyn, Hermanus. (2014). [https://purl.fdlp.gov/GPO/gpo54274 Displaced Left-turn Intersection Informational Guide.] Washington, D.C.: [[United States Department of Transportation|U.S. Department of Transportation]], [[Federal Highway Administration]].</ref> * Other designs include [[advanced stop line]]s, parallel-flow and [[continuous-flow intersection]]s, [[hook turn]]s, [[quadrant roadway intersection|quadrant]]s, [[seagull intersection]]s, [[slip lane]]s, staggered junctions (junctions consisting of two opposing T-junctions where one road intersects two sideroads located diagonally opposite each other; in American English referred to as doglegs), [[superstreet]]s, [[Texas T]]s, [[Texas U-turn]]s and [[turnaround (road)|turnaround]]s.{{clarify|date=November 2014|reason=Should this sentence be under this section?
