Autobahn in the context of Road safety

Road traffic safety refers to the methods and measures, such as traffic calming, to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, motorists, passengers of vehicles, and passengers of on-road public transport, mainly buses and trams.

Best practices in modern road safety strategy:

The Reichsautobahn system was the beginning of the German autobahns under Nazi Germany. There had been previous plans for controlled-access highways in Germany under the Weimar Republic, and two had been constructed, but work had yet to start on long-distance highways. After previously opposing plans for a highway network, the Nazis embraced them after coming to power and presented the project as Hitler's own idea. They were termed "The Fuehrer's roads" ("German: Straßen des Führers") and presented as a major contribution to the reduction of unemployment. Other reasons for the project included enabling Germans to explore and appreciate their country, and there was a strong aesthetic element to the execution of the project under the Third Reich; military applications, although to a lesser extent than has often been thought; a permanent monument to the Third Reich, often compared to the pyramids; and general promotion of motoring as a modernization that in itself had military applications.

Hitler turned the first sod on 23 September 1933, at Frankfurt, and work officially began simultaneously at multiple sites throughout the Reich the following spring. The first finished stretch, between Frankfurt and Darmstadt, opened on 19 May 1935, and the first 1,000 km (620 mi) were completed on 23 September 1936. After the annexation of Austria, the planned network was expanded to include the Ostmark, and a second soil-breaking ceremony for the first Reichsautobahn on formerly Austrian territory took place near Salzburg on 7 April 1938. When work ceased in 1941 because of World War II, 3,819.7 km (2,373.5 mi) had been completed.

A highway is any public or private road or other public way on land. It includes not just major roads, but also other public roads and rights of way. In the United States, it is also used as an equivalent term to controlled-access highway, or a translation for motorway, Autobahn, autostrada, autoroute, etc.

According to Merriam-Webster, the use of the term predates the 12th century. According to Etymonline, "high" is in the sense of "main".

A rest area is a public facility located next to a large thoroughfare such as a motorway, expressway, or highway, at which drivers and passengers can rest, eat, or refuel without exiting onto secondary roads. Other names include motorway service area (UK), services (UK), travel plaza, rest stop, service area, rest and service area (RSA), resto, service plaza, lay-by, and service centre. Facilities may include park-like areas, fuel stations, public toilets, water fountains, restaurants, and dump and fill stations for caravans and motorhomes.

A rest area with limited to no public facilities is a lay-by, scenic area, or scenic overlook. Along some highways and roads are services known as wayside parks, roadside parks, or picnic areas.

Speed limits on road traffic, as used in most countries, set the legal maximum speed at which vehicles may travel on a given stretch of road. Speed limits are generally indicated on a traffic sign reflecting the maximum permitted speed, expressed as kilometres per hour (km/h) or miles per hour (mph) or both. Speed limits are commonly set by the legislative bodies of national or provincial governments and enforced by national or regional police and judicial authorities. Speed limits may also be variable, or in some places nonexistent, such as on most of the Autobahnen in Germany.

The first numeric speed limit for mechanically propelled road vehicles was the 10 mph (16 km/h) limit introduced in the United Kingdom in 1861.

Bundesautobahn 1 (translates from German as Federal Motorway 1, short form Autobahn 1, abbreviated as BAB 1 or A 1) is an autobahn in Germany. It runs from Heiligenhafen in Schleswig-Holstein to Saarbrücken, a distance of 749 km (465 mi), but is incomplete between Cologne and Trier. B 207 continues north from Heiligenhafen to Puttgarden, at the end of the island of Fehmarn, with a ferry to Rødby, Denmark.

The part north of Hamburg is part of the Vogelfluglinie (Migratory Birds Line) and may be one day connected via a fixed link to Denmark (see below). The term Hansalinie (Hansa line) refers to the part from Lübeck (north of Hamburg, thus overlapping the Vogelfluglinie) south to the Ruhr Area (near Dortmund).

Bundesautobahn 2 (translates from German as Federal Motorway 2, short form Autobahn 2, abbreviated as BAB 2 or A 2) is an autobahn in Germany that connects the Ruhr area in the west to Berlin in the east. The A 2 starts at the junction with the A3 near the western city of Oberhausen, passes through the north of the Ruhr valley, through the Münsterland and into Ostwestfalen, crossing the former inner German border and continuing through the Magdeburger Börde to merge into the Berliner Ring shortly before reaching Berlin. Major cities such as Magdeburg, Braunschweig, Hannover and Dortmund are situated very close to the A 2. The A 2 is one of the most important autobahns, connecting several large industrial areas with each other.

The A 2 was modified in the late 1990s, and completely rebuilt in the former East Germany. All of the A 2 has 3 travel lanes and a breakdown lane in each direction.

Krefeld (/ˈkreɪfɛld, -ɛlt/ KRAY-feld, -⁠felt, German: [ˈkʁeːfɛlt] ; Limburgish: Krieëvel [ˈkʀiə˦vəl]), also spelled Crefeld until 1925 (though the spelling was still being used in British papers throughout the Second World War), is a city in North Rhine-Westphalia, in western Germany. It is located northwest of Düsseldorf, its center lying just a few kilometers to the west of the river Rhine; the borough of Uerdingen is situated directly on the Rhine. Because of its economic past, Krefeld is often referred to as the "Velvet and Silk City". It is accessed by the autobahns A57 (Cologne–Nijmegen) and A44 (Aachen–Düsseldorf–Dortmund–Kassel).

Krefeld's residents now speak Hochdeutsch, or standard German, but the native dialect is a Low Franconian variety, sometimes locally called Krefelder Platt, Krieewelsch Platt, or sometimes simply Platt. The Uerdingen line isogloss, separating general dialectical areas in Germany and neighboring Germanic-speaking countries, runs through and is named after Krefeld's Uerdingen district, originally an independent municipality.

The Cologne Bonn Region (German: Region Köln/Bonn) is a metropolitan area in North Rhine-Westphalia (NRW), Germany, covering the cities of Cologne, Bonn and Leverkusen, as well as the districts of Rheinisch-Bergischer Kreis, Oberbergischer Kreis, Rhein-Erft-Kreis and Rhein-Sieg-Kreis. The region covers an area of 3,839 km with 3.13 million inhabitants (population density 815/km). The city centres of Cologne and Bonn are 24 kilometres apart. At the outer city limits, there are only eight kilometres between Cologne-Libur and Bonn-Geislar.

The Cologne/Bonn Region was established by local governments within the Cologne Government Region in 1992, to promote common policies in regional and urban planning, traffic management, environment and investment. Among the most prominent co-operative projects are the Cologne/Bonn Airport, the Verkehrsverbund Rhein-Sieg and the former Bonn–Cologne Railway Company. Also the Stadtbahn of both cities are connected, so there are light rail trains from Cologne Stadtbahn in Bonn and the Bonn Stadtbahn in Cologne. The largest local banks, Sparkasse KölnBonn and Volksbank Köln Bonn, operate in both cities. Both cities are directly connected by the autobahn A555.

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).

A taxiway is a path for aircraft at an airport connecting runways with aprons, hangars, terminals and other facilities. They mostly have a hard surface such as asphalt or concrete, although smaller general aviation airports sometimes use gravel or grass.

Most airports do not have a specific speed limit for taxiing (though some do). There is a general rule on safe speed based on obstacles. Operators and aircraft manufacturers might have limits. Typical taxi speeds are 20–30 kn (37–56 km/h; 23–35 mph).

The autostrada A6 in Poland is a short motorway that starts at the Polish/German border at Kołbaskowo/Pomellen connecting to the German A11 autobahn. It forms a southern bypass of the Szczecin metropolitan area and terminates at Rzęśnica interchange to the east of the city, from where it continues in an expressway standard as S3 towards Świnoujście and S6 towards Gdańsk.Its length is 29.2 km (18.1 mi). The motorway is part of the European route E28.

Reinbek (German: [ˈʁaɪnbeːk] ; probably from "Rainbek" = brook at the field margin; Northern Low Saxon: Reinbeek) is a town located in Stormarn district in the northern German state of Schleswig-Holstein within the metropolitan region of Hamburg. It can be accessed by the A1, the A24 autobahn, federal highway 5 and the S-Bahn line S2.

Reinbek was first mentioned in 1226, the city rights were given in 1952.The town is located at the river Bille which was dammed up here to form a mill pond.

Bundesautobahn 24 (translates from German as Federal Motorway 24, short form Autobahn 24, abbreviated as BAB 24 or A 24) is an autobahn in northern Germany that connects the large metropolitan regions of Hamburg and Berlin. It was one of the three transit access roads to West Berlin during the Cold War. The other 2 being the A2

On that road, there is a 150 km (93 mi) long section that has no speed limit at all (only a recommended speed of 130 km/h), which means that about 65% of that Autobahn can be driven at very high speed.

Bundesautobahn 3 (translates from German as Federal Motorway 3, short form Autobahn 3, abbreviated as BAB 3 or A 3) is an autobahn in Germany running from the Germany-Netherlands border near Wesel in the northwest to the Germany-Austria border near Passau.

Major cities along its total length of 778 km (483 mi) include Oberhausen, Duisburg, Düsseldorf, Leverkusen, Cologne, Wiesbaden, Frankfurt, Würzburg, Nuremberg and Regensburg. The A 3 is a major connection between the Rhine-Ruhr area and southern Germany, resulting in heavy traffic. Consequently, large parts have three lanes (plus a hard shoulder) in each direction, including a 300 km (187.5 mi) section between Oberhausen and Aschaffenburg.

Bundesautobahn 5 (translates from German as Federal Motorway 5, short form Autobahn 5, abbreviated as BAB 5 or A 5) is a 445 km (277 mi) long Autobahn in Germany. Its northern end is the Hattenbach triangle intersection (with the A 7). The southern end is at the Swiss border near Basel. It runs through the German states of Hessen and Baden-Württemberg and connects on its southern ending to the Swiss A 2.

The A5 passes by the Frankfurt Airport.

The Frankfurter Kreuz (Frankfurt Junction) is an Autobahn interchange in Frankfurt am Main, Germany, where the autobahns A3 and A5 meet. The interchange was originally to be built from 1931 to 1933, but due to World War II construction was not finished until 1957.

It underwent massive remodeling in the 1990s, as it had been frequently overloaded due to excess traffic. Today, both autobahns have ten lanes.
