Autobahn in the context of "Reichsautobahn"

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:

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.
