The Alpine Convention is an international territorial treaty for the sustainable development of the Alps . The objective of the treaty is to protect the natural environment of the Alps while promoting its development. This Framework Convention involves the European Union and eight states (Austria, Germany, France, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland). Opened to signature in 1991 and consisting of a Framework Convention, various implementation protocols and declarations, it entered into force in 1995, contributing to reinforce the recognition of special qualities and specific characteristics of the Alps, going beyond national boundaries and seeking international action.
75-736: The Austrian autobahns are controlled-access highways in Austria . They are officially called Bundesstraßen A (Bundesautobahnen) under the authority of the Federal Government according to the Austrian Federal Road Act ( Bundesstraßengesetz ), not to be confused with the former Bundesstraßen highways maintained by the Austrian states since 2002. Ideas to build up a limited-access road network with grade separated interchanges had been developed already in
150-663: A dual highway ) in 1932 between Cologne and Bonn . It then rapidly constructed the first nationwide system of such roads. The first North American freeways (known as parkways) opened in the New York City area in the 1920s. Britain, heavily influenced by the railways, did not build its first motorway , the Preston By-pass ( M6 ), until 1958. Most technologically advanced nations feature an extensive network of freeways or motorways to provide high-capacity urban travel, or high-speed rural travel, or both. Many have
225-466: A median separates the opposite directions of traffic. This strip may be as simple as a grassy area, or may include a crash barrier such as a " Jersey barrier " or an "Ontario Tall Wall" to prevent head-on collisions . On some freeways, the two carriageways are built on different alignments; this may be done to make use of available corridors in a mountainous area or to provide narrower corridors through dense urban areas . Control of access relates to
300-707: A cloverleaf and trumpet interchange when it opened in 1937, and until the Second World War , boasted the longest illuminated stretch of roadway built. A decade later, the first section of Highway 401 was opened, based on earlier designs. It has since gone on to become the busiest highway in the world. The word freeway was first used in February 1930 by Edward M. Bassett . Bassett argued that roads should be classified into three basic types: highways, parkways , and freeways. In Bassett's zoning and property law -based system, abutting property owners have
375-620: A freeway, specialized pedestrian footbridges or tunnels may also be provided. These structures enable pedestrians and cyclists to cross the freeway at that point without a detour to the nearest road crossing. Access to freeways is typically provided only at grade-separated interchanges , though lower-standard right-in/right-out (left-in/left-out in countries that drive on the left) access can be used for direct connections to side roads. In many cases, sophisticated interchanges allow for smooth, uninterrupted transitions between intersecting freeways and busy arterial roads . However, sometimes it
450-434: A larger number of guide signs than other roads, and the signs themselves are physically larger. Guide signs are often mounted on overpasses or overhead gantries so that drivers can see where each lane goes. Exit numbers are commonly derived from the exit's distance in miles or kilometers from the start of the freeway. In some areas, there are public rest areas or service areas on freeways, as well as emergency phones on
525-499: A legal status which limits the types of vehicles that can use a highway, as well as a road design that limits the points at which they can access it. Major arterial roads will often have partial access control , meaning that side roads will intersect the main road at grade, instead of using interchanges, but driveways may not connect directly to the main road, and drivers must use intersecting roads to access adjacent land. At arterial junctions with relatively quiet side roads, traffic
600-527: A milepost system but does not use milepost markers. In Europe and some other countries, motorways typically have similar characteristics such as: Two-lane freeways , often undivided, are sometimes built when traffic volumes are low or right-of-way is limited; they may be designed for easy conversion to one side of a four-lane freeway. (For example, most of the Bert T. Combs Mountain Parkway in eastern Kentucky
675-447: A motorway is understood as a public road with dual carriageways and at least two lanes each way. All entrances and exits are signposted and all interchanges are grade separated. Central barrier or median present throughout the road. No crossing is permitted, while stopping is permitted only in an emergency. Restricted access to motor vehicles, prohibited to pedestrians, animals, pedal cycles, mopeds, agricultural vehicles. The minimum speed
750-777: A national-level or even international-level (e.g. European E route ) system of route numbering . There are several international standards that give some definitions of words such as motorways, but there is no formal definition of the English language words such as freeway , motorway , and expressway , or of the equivalent words in other languages such as autoroute , Autobahn , autostrada , autocesta, autoput , that are accepted worldwide—in most cases these words are defined by local statute or design standards or regional international treaties. Descriptions that are widely used include: One green or blue symbol (like [REDACTED] ) appears at motorway entry in countries that follow
825-548: A number as well as an official name with local reference, which, however, is not displayed on road signs. Unusually for European countries, interchanges (between motorways called Knoten , "knots") are numbered by distance in kilometres starting from where the route begins. That arrangement is also used in the Czech Republic , Slovakia , Hungary , Spain and most Canadian provinces (and in most American states, albeit in miles). The current Austrian Autobahn network has
SECTION 10
#1732782371478900-600: A number of patterns. The actual pattern is determined by a number of factors including local topology, traffic density, land cost, building costs, type of road, etc. In some jurisdictions feeder/distributor lanes are common, especially for cloverleaf interchanges ; in others, such as the United Kingdom, where the roundabout interchange is common, feeder/distributor lanes are seldom seen. Motorways in Europe typically differ between exits and junctions. An exit leads out of
975-624: A park and where intersecting streets crossed over bridges. The Southern State Parkway opened in 1927, while the Long Island Motor Parkway was closed in 1937 and replaced by the Northern State Parkway (opened 1931) and the contiguous Grand Central Parkway (opened 1936). In Germany, construction of the Bonn-Cologne Autobahn began in 1929 and was opened in 1932 by Konrad Adenauer , then
1050-457: A private venture, was the world's first limited-access roadway. It included many modern features, including banked turns , guard rails and reinforced concrete tarmac . Traffic could turn left between the parkway and connectors, crossing oncoming traffic, so it was not a controlled-access highway (or "freeway" as later defined by the federal government's Manual on Uniform Traffic Control Devices ). Modern controlled-access highways originated in
1125-609: A reduction in deaths in a range from 20% to 50% on those sections. Speed, in Europe, is considered to be one of the main contributory factors to collisions. Some countries, such as France and Switzerland, have achieved a death reduction by a better monitoring of speed. Tools used for monitoring speed might be an increase in traffic density; improved speed enforcement and stricter regulation leading to driver license withdrawal; safety cameras; penalty point; and higher fines. Some other countries use automatic time-over-distance cameras (also known as section controls ) to manage speed. Fatigue
1200-541: A separate roadway or altogether eliminates it. In some parts of the world, notably parts of the US , frontage roads form an integral part of the freeway system. These parallel surface roads provide a transition between high-speed "through" traffic and local traffic. Frequent slip-ramps provide access between the freeway and the frontage road, which in turn provides direct access to local roads and businesses. Except on some two-lane freeways (and very rarely on wider freeways),
1275-510: A similar system of express and local lanes for a maximum width of 21 lanes on a 2-mile (3.2 km) segment between Interstate 805 and California State Route 56 . In Mississauga , Ontario, Highway 401 uses collector-express lanes for a total of 18 lanes through its intersection with Highway 403 / Highway 410 and Highway 427 . These wide freeways may use separate collector and express lanes to separate through traffic from local traffic, or special high-occupancy vehicle lanes , either as
1350-411: A special restriction on the innermost lane or a separate roadway, to encourage carpooling . These HOV lanes , or roadways open to all traffic, can be reversible lanes , providing more capacity in the direction of heavy traffic, and reversing direction before traffic switches. Sometimes a collector/distributor road , a shorter version of a local lane, shifts weaving between closely spaced interchanges to
1425-469: A total length of 1,720 km (1,070 mi). The system is going to be expanded; one autobahn is currently under construction, and one more is planned. The transit traffic across the main chain of the Alps , especially by trucks, has led to a considerable environmental load to the fragile Alpine ecosystem. Several action groups urge the transfer of freight transport from road to rail. In 1991, Austria signed
1500-412: A vehicle is on the motorway without a GO-Box or a vignette, or a fine of €240 if a vignette is not affixed onto the windscreen or in one of the approved places or the vehicle is on the motorway with a vignette that has expired or been tampered with. If the driver refuses to pay the fine, then the fine will increase to between €300 and €3,000. Controlled-access highway A controlled-access highway
1575-405: A year). As of 2016, a vignette valid for a year costs €85.70 for cars and €34.10 for motorcycles. To prove to have paid this fee, the toll stickers have to be put onto the inside of the front windscreen. Once removed, they no longer are valid, so each car on Austrian Autobahns needs its own toll sticker. From 2018, digital vignettes are an alternative to toll stickers. Digital vignette is purchased on
SECTION 20
#17327823714781650-454: Is 100 km/h, however on some it is 130 km/h indicated by a sign. The current Schnellstraßen system has a total length of 466 km (290 mi). As they fit better with the mountainous topography of Austria, Schnellstraßen often serve as an autobahn substitute. For example, the main link between the Austria's westernmost state of Vorarlberg and adjacent Tyrol is entirely provided by
1725-453: 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 or thruway 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. In countries following
1800-582: Is considered as a risk factor more specific to monotonous roads such as motorways, although such data are not monitored/recorded in many countries. According to Vinci Autoroutes , one third of accidents in French motorways are due to sleepy driving. Alpine Convention The geographic area of the Alpine Convention covers a 190,717 km or 73,636 sq mi encompassing 5867 municipalities (data from 2013). The Alpine Range as defined by
1875-735: Is controlled mainly by two-way stop signs which do not impose significant interruptions on traffic using the main highway. Roundabouts are often used at busier intersections in Europe because they help minimize interruptions in flow, while traffic signals that create greater interference with traffic are still preferred in North America. There may be occasional interchanges with other major arterial roads. Examples include US 23 between SR 15 's eastern terminus and Delaware, Ohio , along with SR 15 between its eastern terminus and I-75 , US 30 , SR 29 / US 33 , and US 35 in western and central Ohio. This type of road
1950-655: Is necessary to exit onto a surface road to transfer from one freeway to another. One example in the United States (notorious for the resulting congestion) is the connection from Interstate 70 to the Pennsylvania Turnpike ( Interstate 70 and Interstate 76 ) through the town of Breezewood, Pennsylvania . Speed limits are generally higher on freeways and are occasionally nonexistent (as on much of Germany's Autobahn network). Because higher speeds reduce decision time, freeways are usually equipped with
2025-695: Is not directly connected to the main Austrian autobahn network, as via motorway drivers have to use the German autobahns BAB 8 and 93 along the Deutsches Eck link. Austria currently has 18 autobahns, since 1982 built and maintained by the self-financed ASFiNAG stock company in Vienna, which is wholly owned by the Republic of Austria and earns revenue from road user charges and tolls. Each route bears
2100-450: Is not lower than 50 km/h [31 mph] and the maximum speed is not higher than 130 km/h [81 mph] (except Germany where no speed limit is defined). Motorways are designed to carry heavy traffic at high speed with the lowest possible number of accidents. They are also designed to collect long-distance traffic from other roads, so that conflicts between long-distance traffic and local traffic are avoided. According to
2175-431: Is provided with separate carriageways for the two directions of traffic). Principal arterials may cross through urban areas, serving suburban movements. The traffic is characterized by high speeds and full or partial access control (interchanges or junctions controlled by traffic lights). Other roads leading to a principal arterial are connected to it through side collector roads. In this view, CARE's definition stands that
2250-407: Is sometimes called an expressway . Freeways are usually limited to motor vehicles of a minimum power or weight; signs may prohibit cyclists , pedestrians and equestrians and impose a minimum speed. It is possible for non-motorized traffic to use facilities within the same right-of-way, such as sidewalks constructed along freeway-standard bridges and multi-use paths next to freeways such as
2325-480: Is specially sign-posted as a motorway and is reserved for specific categories of road motor vehicles." Urban motorways are also included in this definition. However, the respective national definitions and the type of roads covered may present slight differences in different EU countries. The first version of modern controlled-access highways evolved during the first half of the 20th century. The Long Island Motor Parkway on Long Island , New York , opened in 1908 as

2400-545: Is the result of several changes, including infrastructure safety and road user behavior (speed or seat belt use), while other matters such as vehicle safety and mobility patterns have an impact that has not been quantified. Motorways are the safest roads by design. While accounting for more than one quarter of all kilometres driven, they contributed only 8% of the total number of European road deaths in 2006. Germany's Federal Highway Research Institute provided International Road Traffic and Accident Database (IRTAD) statistics for

Several such roads are infamous for a high rate of lethal crashes; an outcome because they were designed for short sight distances (sufficient for freeways without oncoming traffic, but insufficient for the years in service as two-lane road with oncoming traffic). An example of such a "Highway to Hell"
2550-639: The S16 Arlberg Schnellstraße , including the Arlberg Road Tunnel completed in 1979. Since 1997, the use of all Autobahnen and Schnellstraßen requires the purchase of a vignette (toll sticker) for passenger cars up to 3.5 tonnes or a GO-Box [ de ] (electronic toll system) for trucks and buses. The toll fee ( Maut ) has to be paid to legally access the Austrian Autobahns at any time except
2625-665: The Alpine Convention on the protection of the natural environment. Unlike German autobahns , on Austrian autobahns a general speed limit of 130 km/h (81 mph) is set, although as of August 25, 2018, the ÖVP-FPÖ coalition government had been going on a trial for a possible speed limit increase to 140 km/h (87 mph) on the Autobahn 1 freeway. The trial ended in 2020 with no changes to speed limit. They may only be used by powered vehicles that are designed to achieve at least 60 km/h (37 mph). While on
2700-629: The Dartford Crossing (the furthest downstream public crossing of the River Thames ) or where it was not economic to build a motorway alongside the existing road such as the former Cumberland Gap . The A1 is a good example of piece-wise upgrading to motorway standard—as of January 2013, the 639-kilometre-long (397 mi) route had five stretches of motorway (designated as A1(M)), reducing to four stretches in March 2018 with completion of
2775-867: The Suncoast Trail along the Suncoast Parkway in Florida . In some US jurisdictions, especially where freeways replace existing roads, non-motorized access on freeways is permitted. Different states of the United States have different laws. Cycling on freeways in Arizona may be prohibited only where there is an alternative route judged equal or better for cycling. Wyoming , the second least densely populated state, allows cycling on all freeways. Oregon allows bicycles except on specific urban freeways in Portland and Medford . In countries such as
2850-538: The United Kingdom new motorways require an Act of Parliament to ensure restricted right of way. Since upgrading an existing road (the "King's Highway") to a full motorway will result in extinguishing the right of access of certain groups such as pedestrians, cyclists and slow-moving traffic, many controlled access roads are not full motorways. In some cases motorways are linked by short stretches of road where alternative rights of way are not practicable such as
2925-424: The United Kingdom , do not distinguish between the two, but others make a distinction; for example, Germany uses the words Kreuz ("cross") or Dreieck ("triangle") for the former and Ausfahrt ("exit") for the latter. In all cases one road crosses the other via a bridge or a tunnel, as opposed to an at-grade crossing . The inter-connecting roads, or slip-roads , which link the two roads, can follow any one of

California , Ohio and Nevada use postmile systems in which the markers indicate mileage through the state's individual counties. However, Nevada and Ohio also use the standard milepost system concurrently with their respective postmile systems. California numbers its exits off its freeways according to

3150-650: The 1920s, including a " Nibelungen " highway along the Donau (Danube) river from Passau to Wien (Vienna) and further on towards Budapest . Those plans however had never been carried out due to the lasting economic crisis that hit the country after the dissolution of Austria-Hungary in 1918, exacerbated by the Great Depression . The first autobahn on Austrian territory was the West Autobahn from Salzburg to Vienna . Building started immediately after
3225-501: The A1(M) through North Yorkshire . The most frequent way freeways are laid out is by building them from the ground up after obstructions such as forestry or buildings are cleared away. Sometimes they deplete farmland, but other methods have been developed for economic, social and even environmental reasons. Full freeways are sometimes made by converting at-grade expressways or by replacing at-grade intersections with overpasses; however, in

#17327823714783900-409: The US, any at-grade intersection that ends a freeway often remains an at-grade intersection. Often, when there is a two-lane undivided freeway or expressway, it is converted by constructing a parallel twin corridor, and leaving a median between the two travel directions. The median-side travel lane of the old two-way corridor becomes a passing lane. Other techniques involve building a new carriageway on
3975-484: The United States, allow for limited exceptions: some movable bridges , for instance the Interstate Bridge on Interstate 5 between Oregon and Washington , do require drivers to stop for ship traffic. The crossing of freeways by other routes is typically achieved with grade separation either in the form of underpasses or overpasses . In addition to sidewalks (pavements) attached to roads that cross

In the European Union , for statistical and safety purposes, some distinction might be made between motorway and expressway . For instance a principal arterial might be considered as: Roads serving long distance and mainly interurban movements. Includes motorways (urban or rural) and expressways (road which does not serve properties bordering on it and which
4125-596: The West Autobahn up to Mondsee was opened in 1958, by 1967 the route between Salzburg and Vienna was completed. From 1959 onwards the Süd Autobahn was built to reach the southern state capitals of Graz and Klagenfurt from Vienna. The construction of the Tauern Autobahn was not resumed until 1969. The Inn Valley Autobahn in the western state of Tyrol was built from 1968 onwards, up to today it

London Orbital or the M25 is a motorway surrounding London , but at the last River Thames crossing before its mouth, motorway rules do not apply. (At this crossing the London Orbital is labeled A282 instead.) A few of the more common types of junction are shown below: There are many differences between countries in their geography, economy, traffic growth, highway system size, degree of urbanization and motorization, etc.; all of which need to be taken into consideration when comparisons are made. According to some EU papers, safety progress on motorways

Every 10 years, Contracting Parties have to publish a report concerning the implementation of the convention and its protocols. The first report was adopted at the Xth Alpine Conference (March 2009). The permanent secretariat, created in 2003, supports all the other bodies of the Alpine Convention by providing logistic and administrative support, and by helping
4350-492: The common European definition, a motorway is defined as "a road, specially designed and built for motor traffic, which does not serve properties bordering on it, and which: (a) is provided, except at special points or temporarily, with separate carriageways for the two directions of traffic, separated from each other, either by a dividing strip not intended for traffic, or exceptionally by other means; (b) does not cross at level with any road, railway or tramway track, or footpath; (c)

These original high-speed roads were referred to as " dual highways " and have been modernized and are still in use today. Italy was the first country in the world to build controlled-access highways reserved for fast traffic and for motor vehicles only. The Autostrada dei Laghi ("Lakes Motorway"),
4500-485: The first built in the world, connecting Milan to Lake Como and Lake Maggiore , and now parts of the A8 and A9 motorways, was devised by Piero Puricelli and was inaugurated in 1924.

The Bronx River Parkway was the first road in North America to utilize a median strip to separate the opposing lanes, to be constructed through
4575-412: The first half of the 20th century. Italy was the first country in the world to build controlled-access highways reserved for fast traffic and for motor vehicles only. Italy opened its first autostrada in 1924, A8 , connecting Milan to Varese . Germany began to build its first controlled-access autobahn without speed limits (30 kilometres [19 mi] on what is now A555 , then referred to as

#17327823714784650-504: The highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arterials and collector roads . On the controlled-access highway, opposing directions of travel are generally separated by a median strip or central reservation containing a traffic barrier or grass. Elimination of conflicts with other directions of traffic dramatically improves safety, while increasing traffic capacity and speed. Controlled-access highways evolved during

4800-469: The mayor of Cologne . The German Autobahn became the first nationwide highway system. In Canada , the first precursor with semi-controlled access was The Middle Road between Hamilton and Toronto , which featured a median divider between opposing traffic flow, as well as the nation's first cloverleaf interchange . This highway developed into the Queen Elizabeth Way , which featured
4875-400: The motorway system, whilst a junction is a crossing between motorways or a split/merge of two motorways. The motorway rules end at exits, but not at junctions. However, on some bridges, motorways, without changing appearance, temporarily end between the two exits closest to the bridge (or tunnel), and continue as dual carriageways . This is in order to give slower vehicles a possibility to use
4950-478: The motorway voluntary stops, U-turns and backward driving are prohibited. Schnellstraßen (officially Bundesstraßen S ) are federal limited-access roads very similar to Autobahnen ; the chief difference is that they are more cheaply built with fewer tunnels, mostly just following the given topography. Depending on the road extension, they are either signposted as Autobahn or Autostraße according to Austrian traffic regulations. The speed limit on Schnellstraßen
5025-439: The other. Other methods involve constructing a service drive that shortens the long driveways (typically by less than 100 metres (330 ft)). An interchange or a junction is a highway layout that permits traffic from one controlled-access highway to access another and vice versa, whereas an access point is a highway layout where traffic from a distributor or local road can join a controlled-access highway.

Under the convention, Member States should adopt specific measures in twelve thematic areas (Population and Culture, Spatial Planning, Air pollution, Soil Conservation, Water Management, Conservation of Nature and the Countryside, Mountain Farming, Mountain Forests, Tourism, Transport, Energy, and Waste Management). Of these areas, eight are now protocols annexed to
5250-477: The rate is higher than the risk on urban roads. Speeds are higher on rural roads and autobahns than urban roads, increasing the severity potential of a crash. According to ETSC, German motorways without a speed limit, but with a 130 km/h (81 mph) speed recommendation, are 25% more deadly than motorways with a speed limit. Germany also introduced some 130 km/h (81 mph) speed limits on various motorway sections that were not limited. This generated
5325-643: The rights of light , air and access to highways, but not parkways and freeways; the latter two are distinguished in that the purpose of a parkway is recreation, while the purpose of a freeway is movement. Thus, as originally conceived, a freeway is simply a strip of public land devoted to movement to which abutting property owners do not have rights of light, air or access. Freeways, by definition, have no at-grade intersections with other roads, railroads or multi-use trails .
