A junction where three roads come together and one road ends.

A junction where two roads cross each other at a grade.

A junction where roads form a 'Y' shape and merge or diverge at an acute angle.

A circular intersection with an island in the center, where traffic moves in one direction around the island.

A crossroad managed by traffic lights which regulate the flow of traffic.

A junction where traffic flow is controlled by signs or by default 'right-of-way' rules instead of signals.

A complex junction that separates traffic by levels with bridges and/or tunnels to allow traffic to pass without intersection.

A junction typically associated with highways where local roads cross a highway with on and off ramps.

An interchange with a series of entrance and exit ramps resembling the leaves of a four-leaf clover.

An alternative design where left-turning vehicles cross opposing traffic before the main intersection.

A roundabout with spiral markings that guide drivers into lanes early and reduce conflicting traffic paths.

A junction where drivers are rerouted to make a left turn or sometimes a U-turn from a right-hand lane.

A junction that requires vehicles on the minor road to turn right and then perform a U-turn to go in the opposite direction.

A junction where through movements from side streets are prohibited, and drivers must use a median U-turn instead.

An intersection that adds a new road within a quadrant to avoid turning traffic conflicts at the main intersection.

A type of intersection where side street traffic is required to turn right and then perform a U-turn for other movements.

An innovative intersection design that allows left-turning traffic to cross opposite traffic before the main intersection.

A configuration where each direction of a main road is separated by a barrier and has its own set of signal phases.

A unique turn method where turning vehicles move to the far side of the intersection to make the turn.

A junction where the side roads do not align directly opposite each other, creating two separate T-intersections.

An interchange that spans over three vertically separated levels, allowing for free-flow movement in multiple directions.

A highway interchange where a single traffic signal controls all turning movements.

A highway interchange that temporarily shifts traffic to the opposite side of the road to facilitate left-turning movements.

An intersection that connects two roundabouts in close proximity, sometimes referred to as a 'dogbone' intersection.

A staggered intersection that splits roadway into discrete segments with controlled entry and exit points, to allow smooth traffic flow.

Redirects turning traffic to a parallel roadway prior to rejoining the main road, improving flow and safety.

A T-intersection that allows a right-turn from a minor road without stopping, as the major road through lane doesn't have to stop.

Resembles a cloverleaf interchange but with fewer loops, often utilizing ramps instead.

Characterized by the four ramps of a diamond interchange that connect to the intersecting road at 45-degree angles, forming a pinwheel shape.
