		Diamond interchanges are used where a freeway crosses a minor road.
		In the United States, where this form of interchange is very common, particularly in rural areas, traffic on the off-ramp typically faces a stop sign at the minor road, while traffic turning onto the freeway is unrestricted.
		The diamond interchange makes more efficient use of space than most types of freeway interchange, and avoids the interweaving traffic flows that occur in interchanges such as the cloverleaf.

	Interchange (road) - Wikipedia, the free encyclopedia
		In the field of road transport, an interchange is a road junction that utilizes grade separation, and one or more ramps, to permit traffic on at least one road to pass through the junction without crossing any other traffic stream.
		A trumpet is an interchange traditionally used where one freeway terminates at another freeway; it involves at least one loop ramp (for traffic leaving the terminating freeway) whose overpass is shared by traffic connecting to the terminating freeway.
		Dumbbell interchange - this is similar to a diamond except that it uses roundabouts rather than signals or stop signs where the ramps meet the non-freeway road.

	Parclo interchange - Psychology Central (Site not responding. Last check: 2007-10-12)
		The parclo interchange (short for partial cloverleaf interchange) is a successor to the cloverleaf interchange.
		The parclo interchange was developed by the Ontario Ministry of Transportation [1] as a replacement for the cloverleaf on 400-Series Highways, removing the dangerous weaving patterns and allowing for more acceleration and deceleration space on the freeway.
		In the United States, folded diamonds are frequently used in interchanges with roads that have a railroad line closely paralleling the surface street; entrance/exit ramps are not permitted to have level crossings in modern American practice.

		An interchange that results in two or more closely spaced surface intersections, so that one connection is made to each freeway entry and exit, with one connection per quadrant.
		A diamond interchange with fewer than four ramps so that not all of the freeway-street or street-freeway movements are served.
		Diamond interchanges in which freeway entry and exit ramps are separated at the street level, creating four intersections.

		A (partial cloverleaf) interchange with loops in advance of the minor road with direction of travel on the freeway; and in the same interchange area, an interchange with loops beyond the minor road.
		Lighting on an interchange that consists of a few luminaires located in the general areas where entrance and exit ramps connect with the through traffic lanes of a freeway (between the entry gore and the end of the acceleration ramp or exit gore and the beginning of the deceleration ramp).
		A three-leg interchange where a connecting highway terminates and where only a small amount of traffic moves between the terminating highway and one of the two legs of the freeway.

		Divergent margins are characterized by extensive normal faulting, low-magnitude earthquakes, and, in most cases, volcanic activity.
		The most common type of divergent margin is the oceanic spreading centre, where two oceanic plates move apart.
		The second type of divergent margin occurs on the continents, in regions of incipient continental break-up.

	Single-point urban interchange - Wikipedia, the free encyclopedia
		A single point urban interchange (SPUI, pronounced spoo-ee, rhymes with phooey), also called a single point interchange (SPI) or single point diamond interchange (SPDI), is a type of highway interchange.
		It is similar in form to a diamond interchange but has the advantage of allowing opposing left turns to proceed simultaneously, by compressing the two intersections of a diamond into one single intersection over or under the free-flowing road.
		Also, a SPUI generally has a very large area of uncontrolled pavement in the middle of the intersection because vehicles must be able to cross the pavement in six different ways.

	Left-side driving part of a planned Findlay, Ohio interchange reconfiguration - Wikinews
		Plans for the interchange, a standard diamond interchange that also carries State Highway 15 on the west and south approaches, include reversing the flow of traffic on the bridge over I-75, in what is known as a "diverging diamond interchange".
		Such an interchange does not exist in the United States; ODOT based the plan on an interchange in Versailles, France of the same design, introduced to them by a report in a trade magazine.
		The land west of the interchange, across from downtown Findlay, is being rapidly developed, and plans for the area include a Wal-Mart.

		The remarkable line of volcanoes around the whole coast of the Pacific and along the margin of the Caribbean and Mediterranean seas is one of the most conspicuous features of the globe.

		The functions of land forms extend beyond the control of the circulation of the atmosphere, the hydrosphere and the water which is continually being interchanged between them; they are exercised with increased effect in the higher departments of biogeography and anthropogeography.

	Junction (road) - Wikipedia, the free encyclopedia
		Interchanges are junctions where roads pass above or below one another, preventing a single point of conflict by utilising grade separation and slip roads.
		Intersections do not use grade separation (they are at-grade) and roads cross directly.

	RATIONALE AND SUPPORTING EVIDENCE
		An assumption in the development of the exit model was that the speed of an exiting vehicle during the diverge steering maneuver is constant, and therefore the speed of the vehicle during the diverge equals the freeway speed.
		Examples of locations at interchange ramps where DSD is desirable include ramp terminals at the main road, especially at an exit terminal beyond the grade separation and at left exits; ramp terminals at the cross road; lane drops; and abrupt or unusual alignment changes.
		In addition, the findings at the level of one interchange were translated to estimate, as an overall annual impact for the five-State sample, the relative influence of the lighting variables on numbers of accidents at interchanges through three levels of night traffic volume.

		A diverging diamond interchange is a rare form of diamond interchange in which the two directions of traffic on the non-freeway road cross to the opposite side on both sides of the bridge at the freeway.
		It is unusual in that it requires traffic on the freeway overpass (or underpass) to briefly drive on the opposite side of the road from that which they are accustomed.

		Other factors to be considered include interchange frequency and spacing, the simultaneous impacts of horizontal and vertical curve alignment, and the roadside environment and potential distractions (e.g., advertising signage).
		The MUTCD (1) also states that Reference Posts (e.g., mile markers at 0.1 mile intervals) may be installed along any section of a highway route to assist road users in estimating their progress, to provide a means for identifying the location of emergency incidents and traffic accidents, and to aid in highway maintenance and servicing.
		The MUTCD requires that single delineators be provided on the right side of expressways and freeways and on at least one side of interchange ramps, except in a few cases (e.g., on sections of roadways where continuous lighting is in operation between interchanges.
