Michigan left. Standard design on a wide median [1] Stylized depiction of the design in Grand Haven, Michigan, at US 31 and Robbins Road (north to the right), showing the additional area necessary to make a turn on a narrow median [1] 43°2′40.18″N 86°13′12.57″W. A Michigan left or P-turn is an at-grade intersection design that ...
An intersection where vehicles attempting to turn across the opposing direction of traffic (left in right-hand drive jurisdictions; right in left-hand drive jurisdictions) cross before they enter the intersection. No left turn signal in the intersection is then necessary. Continuous green T-intersection. See seagull intersection. Contraflow ...
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design.
A continuous flow intersection (CFI), also called a crossover displaced left-turn (XDL or DLT), is an alternative design for an at-grade road junction. Vehicles attempting to turn across the opposing direction of traffic (left in right-hand drive jurisdictions; right in left-hand drive jurisdictions) cross before they enter the intersection.
Intersection sight distance is the sight distance needed to safely proceed through an intersection. The distance needed depends on the type of traffic control at the intersection (uncontrolled, yield sign, stop sign or signal), and the maneuver (left turn, right turn, or proceeding straight).
A diverging diamond interchange (DDI), also called a double crossover diamond interchange (DCD), [ 1 ][ 2 ] is a subset of diamond interchange in which the opposing directions of travel on the non- freeway road cross each other on either side of the interchange so that traffic crossing the freeway on the overpass or underpass is operating on ...
Two cars are involved in a side collision at an intersection in Tokyo, Japan. A side collision is a vehicle crash where the side of one or more vehicles is impacted. These crashes typically occur at intersections, in parking lots, and when two vehicles pass on a multi-lane roadway.
A roundabout, a rotary and a traffic circle are types of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction. [ 1 ][ 2 ] In the USA, engineers use the term modern roundabout to refer to junctions installed after ...
