[4] The results were: At peak times on the "free-flowing" section of A 9, over 60% of road users exceeded the recommended 130km/h (81mph) maximum speed, more than 30% of motorists exceeded 150km/h (93mph), and more than 15% exceeded 170km/h (106mph)in other words the so-called "85th-percentile speed" was in excess of 170km/h.[106]. Up to a speed of 60km/h (37mph), if the left lane is crowded or driving slowly, it is permitted to pass cars on the right side if the speed difference is not greater than 20km/h (12mph), "Autobahn", a song by South Korean Boyband, * original plan: number is used by another route now, This page was last edited on 3 March 2023, at 20:16.

Certain limits are imposed on some classes of vehicles: Additionally, speed limits are posted at most on- and off-ramps and interchanges[30] and other danger points like sections under construction or in need of repair. The Autobahn (IPA: [atoban] (listen); German plural Autobahnen) is the federal controlled-access highway system in Germany. Some lower-performance models have lower speed limiters in order to avoid exceeding their tires' limitations. At some point, a speed limit will become reality here, and soon we will not be able to remember the time before. Some roads have night-time or wet-weather speed limits, and some classes of vehicles, such as heavy trucks, have their own speed limits. In the 1930s, a ten-kilometre stretch of what is today Bundesautobahn 9 just south of Dessaucalled the Dessauer Rennstreckehad bridges with no piers and was designed for cars like the Mercedes-Benz T80 to attempt to make land speed records. ", "Tempolimit: Warum Deutschlands Autobahnen ein Sonderfall sind", "Therapievorschlag: Tempolimit 120 auf deutschen Autobahnen", "Scheuers Behauptung im Faktencheck: Sind deutsche Autobahnen die sichersten Straen der Welt? German national speed limits have a historical association[36] with war-time restrictions and deprivations, the Nazi era, and the Soviet era in East Germany. Due to its location in central Europe Germany tends to see a lot of through traffic and the Autobahn is generally the preferred route. In the 1930s, when construction began on the system, the official name was Reichsautobahn. Asphalt Pavement Thickness and Mix Design - Asphalt Institute Environmentalists argued that enforcing limits of 100km/h (62mph) limit on autobahns and 80km/h (50mph) on other rural roads would save lives as well as the forest, reducing the annual death toll by 30% (250 lives) on autobahns and 15% (1,000 lives) on rural roads;[60] the German motor vehicle death toll was about 10,000 at the time.

Truck stops (German Autohof, plural Autohfe) are large filling stations located at general exits, usually at a small distance from the autobahn, combined with fast food facilities and/or restaurants, but have no ramps of their own. Driving in Germany is regulated by the Straenverkehrs-Ordnung (road traffic regulations,[107] abbreviated StVO). The Nazi party initially opposed a highway network on the grounds that it would primarily benefit the rich aristocrats who could afford a car. The roads around NYC are mostly asphalt but there is concrete underneath for a roadbed. MS-22S Principios de Construccion de Pavimentos de Mezcla Asfaltica en Caliente. When Germany was reunified in 1989, the Autobahns of East Germany were in virtually the same condition as they were in 1945, exhibiting the aforementioned qualities as well as mediocre signing, poor pavement, widely-spaced and often non-functional emergency telephones, and service areas consisting of a dilapidated roadhouse next to a short wayside. For breaks during longer journeys, parking sites, rest areas, and truck stops are distributed over the complete Autobahn network. All of this can take up to six months to finish up, if it's all donesuccessfully, and it could cost over $2000. Repair generally involves replacing sections of the roadway rather than patching, which sounds like a dream here in the U.S. Driving the high-speed sections of the autobahn in Germany is not a matter of simply flooring the accelerator and watching the speedo climb. They have their own white-on-blue signs and numbering system. [57], In the mid-1980s, acid rain and sudden forest destruction renewed debate on whether or not a general speed limit should be imposed on autobahns. [56] The fatality rate trend on the German autobahn mirrored those of other nations' motorways that imposed a general speed limit. This was a very interesting article! [58][59] A car's fuel consumption increases with high speed, and fuel conservation is a key factor in reducing air pollution. I'm unsure as to the thickness but the top layer of asphalt is only about 4-6 inches maybe. [50] Automakers projected a 20% plunge in sales, which they attributed in part to the lowered speed limits.

In 2006, speeds were recorded using automated detection loops in the State of Brandenburg at two points: on a six-lane section of A 9 near Niemegk with a 130km/h (81mph) advisory speed limit; and on a four-lane section of A 10 bypassing Berlin near Gro Kreutz with a 120km/h (75mph) mandatory limit. Thankfully that's something you rarely have to worryabout while on the Autobahn. [citation needed] However, according to one source autobahn workers were often conscripted through the compulsory Reich Labor Service (and thereby removed from the unemployment registry). Does the Autobahn have curves? The earliest motorways were flanked by shoulders about 60 centimetres (24in) in width, constructed of varying materials; right-hand shoulders on many autobahns were later retrofitted to 120 centimetres (47in) in width when it was realized cars needed the additional space to pull off the autobahn safely. Because Germans pay such close attention to this rule, traffic is able to flow much more freely on their highways.

The Nazi government passed the Road Traffic Act in 1934, limiting speeds to 60 kph (37 mph) in urban areas but setting no limit for rural roads or autobahns. [54] Accordingly, the Federal Highway Research Institute conducted a multiple-year experiment, switching between mandatory and recommended limits on two test stretches of autobahn. However, there are many differences between countries in their geography, economy, traffic growth, highway system size, degree of urbanization and motorization, and so on.
