Carriageway
A carriageway (British English) or roadway (North American English) is a width of road on which a vehicle is not restricted by any physical barriers or separation to move laterally. A carriageway generally consists of a number of traffic lanes together with any associated shoulder, but may be a sole lane in width (for example, a highway offramp). Description A single carriageway road (North American English: undivided highway) has one carriageway with 1, 2 or more lanes together with any associated footways (North American English: sidewalk) and road verges (North American English: tree belt, parkway, or other regional variants). A dual carriageway road (North American English: divided highway) has two roadways separated by a central reservation (North American English: median). A local-express lane system (also called collector-express or collector-distributor) has more than two roadways, typically two sets of 'local lanes' or 'collector lanes' and also two sets of 'expre ...

Single Carriageway
A single carriageway (British English) is a road with one, two or more lanes arranged within a one carriageway with no central reservation, central reservation/median strip to separate opposing flows of traffic. A single-track road is a type of single carriageway with a single lane with passing places for traffic in both directions. An undivided highway (American English) is the term used for motorways with two or more lanes with no central reservation/median strip. Road traffic safety is generally worse for high-speed single carriageways than for dual carriageways due to the lack of separation between traffic moving in opposing directions. Countries Ireland The term ''single carriageway'' is used for roads in Republic of Ireland, Ireland. Road speed limits in the Republic of Ireland, Speed limits on single-carriageway roads vary depending on their classification: national primary roads and national secondary roads have a general speed limit of , while Regional road (Ireland), ...

Chaussee
''Chaussee'' is an historic term used in German-speaking countries for early, metalled, rural highways, designed by road engineers, as opposed to the hitherto, traditional, unpaved country roads. The term is no longer used in modern road construction in Western Europe, but survives in road names and is used by historians. In Eastern Europe and the post-Soviet states it remains a generic term for a common paved highway outside of built-up areas, but they may transition into prospekts within towns and cities. Origin of the word and usage The German word was borrowed from the French by the German construction industry in the 18th century. The French word, in turn, went back to the Gallo-Romanic and meant a road surfaced with firmly compacted crushed rock bound with lime. :fr:Chaussée Contemporary German translations of the word were ('road embankment') and ('high way') and even the roughly similar English word, highway. Around 1790, Adelung complained that "several new aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interstate 95
Interstate 95 (I-95) is the main north–south Interstate Highway on the East Coast of the United States, running from U.S. Route 1 (US 1) in Miami, Florida, north to the Houlton–Woodstock Border Crossing between Maine and the Canada, Canadian province of New Brunswick. The highway largely parallels the Atlantic Ocean, Atlantic coast and US 1, except for the portion between Savannah, Georgia, and Washington, D.C., and the portion between Portland, Maine, Portland and Houlton, Maine, Houlton in Maine, both of which follow a more direct inland route. I-95 serves as the principal road link between the major cities of the East Coast of the United States, Eastern Seaboard. Major metropolitan areas along its route include Miami metropolitan area, Miami, Jacksonville metropolitan area, Jacksonville, and Savannah metropolitan area, Savannah in the Southeastern United States, Southeast; Greater Richmond Region, Richmond, Washington metropolitan area, Washington, Bal ...

Road
A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are paved. The words "road" and "street" are commonly considered to be interchangeable, but the distinction is important in urban design. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically, many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stab ...

Geometric Design Of Roads
The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in geometric design are to optimize efficiency and safety while minimizing cost and environmental damage. Geometric design also affects an emerging fifth objective called "livability", which is defined as designing roads to foster broader community goals, including providing access to employment, schools, businesses and residences, accommodate a range of travel modes such as walking, bicycling, transit, and automobiles, and minimizing fuel use, emissions and environmental damage. Geometric roadway design can be broken into three main parts: alignment, profile, and cross-section. Combined, they provide a three-dimensional layout for a roadway. * The alignment is the route of the road, defined as a series of horizontal tangents and curves. * The profile is the vertical aspect of th ...

Frontage Road
A frontage road (also known as an access road, outer road, service road, feeder road, or parallel road) is a local road running parallel to a higher-speed, limited-access road. Where parallel high-speed roads are provided as part of a major highway, these are also known as local lanes. Sometimes a similar arrangement is used for city roads; for example, the collector portion of Commonwealth Avenue in Boston, Massachusetts, is known as a carriage road. A frontage road is often used to provide access to private driveways, shops, houses, industries or farms that would otherwise be cut off by a limited-access road. This can prevent the commercial disruption of an urban area that the freeway traverses or allow commercial development of bordering property. Advantages There are several advantages to using frontage roads. One advantage is to separate local traffic from through traffic. When frontage roads are lacking in an urban area, the highway is used as a local road, red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High-occupancy Vehicle Lane
A high-occupancy vehicle lane (also known as an HOV lane, carpool lane, diamond lane, 2+ lane, and transit lane or T2 or T3 lanes) is a restricted traffic lane reserved for the exclusive use of vehicles with a driver and at least one passenger, including carpools, vanpools, and transit buses. These restrictions may be only imposed during peak travel times or may apply at all times. There are different types of lanes: temporary or permanent lanes with concrete barriers, two-directional or reversible lanes, and exclusive, concurrent, or contraflow lanes working in peak periods. The normal minimum occupancy level is two or three occupants. Many jurisdictions exempt other vehicles, including motorcycles, charter buses, emergency and law enforcement vehicles, low-emission and other green vehicles, and/or single-occupancy vehicles paying a toll. HOV lanes are normally introduced to increase average vehicle occupancy and persons traveling with the goal of reducing traffic congestion ...
