A road is a thoroughfare for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, whose primary function is to serve as public spaces, the main function of roads is transportation.
Autobahn is the German word for a major high-speedroad restricted to motor vehicles capable of driving at least 60 km/h (37 mph) and having full control of access, similar to a motorway or freeway in English-speaking countries.
In most countries, it usually refers to the German autobahn specifically. The recommended speed of the German autobahn is 130 km/h (81 mph), but there is no general speed limit. Austrian and Swiss autobahns have general speed limits of 130 km/h (81 mph) and 120 km/h (75 mph), respectively. In German, the word is pronounced as described above, and its plural is Autobahnen; in English, however, the segment "auto" is typically pronounced as in other English words such as "automobile". The official name of the autobahn in Germany is Bundesautobahn (BAB) (Federal Freeway).
Autobahns are built and maintained by the federal government (as are the federal highways), thus the name "Federal Freeway". The first were built in the 1920s, and in the 1930s the official name was "Reichsautobahn" (Freeways of the Reich).

Image 27Car fatalities per pax-km vs. car usage per pax-day; in Europe. It seems, at least in these European countries, that car fatalities per person-km have no strong correlation with massification of car usage. The average car usage in these countries is around 30km per person-day with varying number of fatalities ratios. These differences might be related with different cultural approaches to traffic codes, or more safety measures implemented on such countries. (from Road traffic safety)
