Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation.
The Bronx River Parkway is a 19.12-mile (30.77 km) long parkway in downstate New York in the United States. It is named for the nearby Bronx River, which it parallels. The southern terminus of the parkway is at Story Avenue near the Bruckner Expressway in the Bronx neighborhood of Soundview. The northern terminus is at the Kensico Circle in Valhalla, Mount Pleasant, Westchester County, where the parkway connects to the Taconic State Parkway and, via a short connector, New York State Route 22 (NY 22). Within the Bronx, the parkway is maintained by the New York State Department of Transportation and is designated New York State Route 907H (NY 907H), an unsigned reference route. In Westchester County, the parkway is maintained by the Westchester County Department of Public Works and is designated unsigned County Route 9987 (CR 9987).
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 warning sign is a type of sign which indicates a potential hazard, obstacle, or condition requiring special attention. Some are traffic signs that indicate hazards on roads that may not be readily apparent to a driver.
A shoulder, hard shoulder (British) or breakdown lane, is an emergency stopping lane by the verge of a road or motorway, on the right side in countries which drive on the right, and on the left side in countries which drive on the left. Many wider (U.S.) freeways, or expressways elsewhere have shoulders on both sides of each directional carriageway — in the median, as well as at the outer edges of the road, for additional safety. Shoulders are not intended for use by through traffic, although there are exceptions.
In road transport, a lane is part of a roadway that is designated to be used by a single line of vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (highways) have at least two lanes, one for traffic in each direction, separated by lane markings. On multilane roadways and busier two-lane roads, lanes are designated with road surface markings. Major highways often have two multi-lane roadways separated by a median.
A U-turn in driving refers to performing a 180° rotation to reverse the direction of travel. It is called a "U-turn" because the maneuver looks like the letter U. In some areas, the maneuver is illegal, while in others, it is treated as a more ordinary turn, merely extended. In still other areas, lanes are occasionally marked "U-turn permitted" or even "U-turn only."
A diamond interchange is a common type of road junction, used where a controlled-access highway crosses a minor road.
A single-point urban interchange, also called a single-point interchange (SPI) or single-point diamond interchange (SPDI), is a type of highway interchange. The design was created in order to help move large volumes of traffic through limited amounts of space safely and efficiently.
A jughandle is a type of ramp or slip road that changes the way traffic turns left at an at-grade intersection. Instead of a standard left turn being made from the left lane, left-turning traffic uses a ramp on the right side of the road. In a standard forward jughandle or near-side jughandle, the ramp leaves before the intersection, and left-turning traffic turns left off of it rather than the through road. Right turns are also made using this type of jughandle. In a reverse jughandle or far-side jughandle, the ramp leaves after the intersection, and left-turning traffic loops around to the right and merges with the crossroad before the intersection.
Road surface marking is any kind of device or material that is used on a road surface in order to convey official information; they are commonly placed with road marking machines. They can also be applied in other facilities used by vehicles to mark parking spaces or designate areas for other uses. In some countries and areas, road markings are conceived as horizontal traffic signs, as opposed to vertical traffic signs placed on posts.
In the field of road transport, an interchange or a grade-separated junction is a road junction that uses grade separations to allow for the movement of traffic between two or more roadways or highways, using a system of interconnecting roadways to permit traffic on at least one of the routes to pass through the junction without interruption from crossing traffic streams. It differs from a standard intersection, where roads cross at grade. Interchanges are almost always used when at least one road is a controlled-access highway or a limited-access divided highway (expressway), though they are sometimes used at junctions between surface streets.
The Warringah Freeway is a 3-kilometre (1.9 mi) divided freeway in Sydney, New South Wales that is part of the Sydney Orbital Network and the Highway 1. The primary function of the freeway is to provide an alternative high-grade route from the Sydney Harbour Tunnel and the Bradfield Highway at Milsons Point to the A8 and the Gore Hill Freeway. The freeway reduces traffic demands on the Pacific Highway throughout Sydney's Lower North Shore, bypassing North Sydney and Crows Nest. Completed in a series of stages between June 1968 and August 1992, the Warringah Freeway provides a vital link to access most of the suburbs in Sydney and is also a major route to the north, south, east and west of the central business district.
Road signs in Malaysia are standardised road signs similar to those used in Europe but with certain distinctions. Until the early 1980s, Malaysia closely followed Australian, Irish and Japanese practice in road sign design, with diamond-shaped warning signs and circular restrictive signs to regulate traffic. Signs usually use the Transport Heavy font on non-tolled roads and highways. Tolled expressways signs use a font specially designed for the Malaysian Highway Authority (LLM) which is LLM Lettering. It has two type of typefaces, LLM Narrow and LLM Normal. Older road signs used the FHWA Series fonts typeface also used in the United States, Canada, and Australia.
The A8 is one of Sydney, Australia's metropolitan arterial routes, formerly designated Metroad 10. The A8 route runs for 23 kilometres from North Sydney to Mona Vale. The route includes parts of several different roads.
A box junction is a road traffic control measure designed to prevent congestion and gridlock at junctions. The surface of the junction is typically marked with a yellow criss-cross grid of diagonal painted lines, and vehicles may not enter the area so marked unless their exit from the junction is clear, or they are intending to turn and are prevented from doing so by oncoming traffic, or other vehicles on the box waiting to turn.
In the United States, road signs are, for the most part, standardized by federal regulations, most notably in the Manual on Uniform Traffic Control Devices (MUTCD) and its companion volume the Standard Highway Signs (SHS).
Terminology related to road transport—the transport of passengers or goods on paved routes between places—is diverse, with variation between dialects of English. There may also be regional differences within a single country, and some terms differ based on the side of the road traffic drives on. This glossary is an alphabetical listing of road transport terms.
Yellow lines are road markings used in various territories.
Road signs in the Philippines are regulated and standardized by the Department of Public Works and Highways (DPWH). Most of the signs reflect minor influences from US and Australian signs, but keep a design closer to the Vienna Convention on Road Signs and Signals in which the Philippines is an original signatory.
