Transportation in France relies on one of the densest networks in the world with 146 km of road and 6.2 km of rail lines per 100 km2. It is built as a web with Paris at its center. Rail, road, air and water are all widely developed forms of transportation in France.
The M4, originally the London-South Wales Motorway, is a motorway in the United Kingdom running from west London to southwest Wales. The English section to the Severn Bridge was constructed between 1961 and 1971; the Welsh element was largely complete by 1980, though a non-motorway section around Briton Ferry bridge remained until 1993. On the opening of the Second Severn Crossing in 1996, the M4 was rerouted over it.
The Great Britain road numbering scheme is a numbering scheme used to classify and identify all roads in Great Britain. Each road is given a single letter and a subsequent number. Though this scheme was introduced merely to simplify funding allocations, it soon became used on maps and as a method of navigation. There are two sub-schemes in use: one for motorways, and another for non-motorway roads.
The A34 is a major road in England. It runs from the A33 and M3 at Winchester in Hampshire, to the A6 and A6042 in Salford, close to Manchester City Centre. It forms a large part of the major trunk route from Southampton, via Oxford, to Birmingham, The Potteries and Manchester. For most of its length, it forms part of the former Winchester–Preston Trunk Road. Improvements to the section of road forming the Newbury Bypass around Newbury were the scene of significant direct action environmental protests in the 1990s. It is 151 miles (243 km) long.
The island of Ireland, comprising Northern Ireland and the Republic of Ireland, has an extensive network of tens of thousands of kilometres of public roads, usually surfaced. These roads have been developed and modernised over centuries, from trackways suitable only for walkers and horses, to surfaced roads including modern motorways. Driving is on the left-hand side of the road. The major routes were established before Irish independence and consequently take little cognisance of the border other than a change of identification number and street furniture. Northern Ireland has had motorways since 1962, and has a well-developed network of primary, secondary and local routes. The Republic started work on its motorway network in the early 1980s; and historically, the road network there was once somewhat less well developed. However, the Celtic Tiger economic boom and an influx of European Union structural funding, saw national roads and regional roads in the Republic come up to international standard quite quickly. In the mid-1990s, for example, the Republic went from having only a few short sections of motorway to a network of motorways, dual carriageways and other improvements on most major routes as part of a National Development Plan. Road construction in Northern Ireland now tends to proceed at a slower pace than in the Republic, although a number of important bypasses and upgrades to dual carriageway have recently been completed or are about to begin.
A trunk road, trunk highway, or strategic road is a major road, usually connecting two or more cities, ports, airports and other places, which is the recommended route for long-distance and freight traffic. Many trunk roads have segregated lanes in a dual carriageway, or are of motorway standard.
A dual carriageway (BrE) or a divided highway (AmE) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation (BrE) or median (AmE). Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways.
A routenumber, designation or abbreviation is an identifying numeric designation assigned by a highway authority to a particular stretch of roadway to distinguish it from other routes and, in many cases, also to indicate its classification, general geographical location and/or orientation. The numbers chosen may be used solely for internal administrative purposes; however, in most cases they are also displayed on roadside signage and indicated on maps.
The road hierarchy categorizes roads according to their functions and capacities. While sources differ on the exact nomenclature, the basic hierarchy comprises freeways, arterials, collectors, and local roads. Generally, the functional hierarchy can more or less correspond to the hierarchy of roads by their owner or administrator.
A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, and partial controlled-access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway, including limited or no access to adjacent property, some degree of separation of opposing traffic flow, use of grade separated interchanges to some extent, prohibition of slow modes of transport, such as bicycles, (draught) horses, or self-propelled agricultural machines; and very few or no intersecting cross-streets or level crossings. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include throughway and parkway. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic.
Road signs in the United Kingdom and in its associated Crown dependencies and overseas territories conform broadly to European design norms, though a number of signs are unique: direction signs omit European route numbers and road signs generally use the Imperial System of units, unlike the rest of Europe. Signs in Wales and parts of Scotland are bilingual.
The autoroute system in France consists largely of toll roads. It is a network of 11,882 km (7,383 mi) of motorways as of 2014. On road signs, autoroute destinations are shown in blue, while destinations reached through a combination of autoroutes are shown with an added autoroute logo. Toll autoroutes are signalled with the word péage.
The United Kingdom has a well developed and extensive network of roads totalling about 262,300 miles (422,100 km). Road distances are shown in miles or yards and UK speed limits are indicated in miles per hour (mph) or by the use of the national speed limit (NSL) symbol. Some vehicle categories have various lower maximum limits enforced by speed limiters. A unified numbering system is in place for Great Britain, whilst in Northern Ireland, there is no available explanation for the allocation of road numbers.
A national primary road is a road classification in Ireland. National primary roads form the major routes between the major urban centres. There are 2649 km of national primary roads. This category of road has the prefix "N" followed by one or two digits. Motorways are prefixed "M" followed by one or two digits.
There have been routes and trackways in Ireland connecting settlements and facilitating trade since ancient times and the country now has an extensive network of public roads connecting all parts of the island.
This article describes the highway systems available in selected countries.
Roads in Ghana form a network of varied quality and capacity. Responsibility for the road network differs between trunk and non-trunk routes. Trunk roads, which are the most important roads, are administered by the Ghana Highway Authority, which was established in 1974 to develop the trunk road network. Ghana's 13,367 km of trunk roads accounts for 33% of the total road network of 40,186 km. The Department of Feeder Roads is responsible for the construction and maintenance of feeder roads in Ghana, while responsibility for urban roads lies with the Department of Urban Roads. In the 18th and 19th centuries, the Ashanti Empire constructed a complex network of roads to link Kumasi with their territories in modern Ghana. For John Thornton, these roads improved transportation across the region by the 19th century.
With 139,000 km of public roads, the Netherlands has one of the most dense road networks in the world – much denser than Germany and France, but still not as dense as Belgium. In 2013, 5,191 km were national roads, 7,778 km were provincial roads, and 125,230 km were municipality and other roads. Dutch roads include 3,530 km of motorways and expressways, and with a motorway density of 64 kilometres per 1,000 km2, the country also has one of the densest motorway networks in the world. In Dutch a motorway is called "autosnelweg" or simply "snelweg"; other expressways are just called "autoweg". According to a 2004 estimate, some 12,500 km of road remain as yet unpaved.
Botswana has a network of roads, of varied quality and capacity, totaling about 31,747 kilometres (19,727 mi). Other these, 20,000 kilometres (12,000 mi) are paved (this is including 134 kilometres of motorways. The reminder 11,747 kilometres worth are unpaved. Road distances are shown in kilometers and Botswana speed limits are indicated in kilometers per hour or by the use of the national speed limit symbol. Some vehicle categories have various lower maximum limits enforced by speed limits, for example trucks.
