The Brazilian Highway System (Portuguese: ''Sistema Nacional de Rodovias'') is the highway system of Brazil. , the system consists of almost 2 million kilometers of roads, of which approximately 200,000 km are paved. As it is in the United States, Canada or most countries in Europe, larger/wider highways have higher speed limits than normal urban roads (typically between 80 km/h and 120 km/h), although minor highways, unpaved highways and sections of major highways running inside urban areas have a lower speed limit in general. The national speed limit for cars driving in non-urban roads is 110 km/h unless otherwise stated, regardless of the road design, weather or daylight. ==Nomenclature== Brazilian Regional highways are named YY-XXX, where YY is the abbreviation of the state where the highway is running in and XXX is a number (e.g. SP-280; where SP means that the highway is under São Paulo state administration). Brazilian National highways are named BR-XXX. National highways connect multiple states altogether, are of major importance to the national economy and/or connect Brazil to another country. The meaning of the numbers are: *000-099 - it means that the highway runs radially from Brasília. It is an exception to the cases below. *100-199 - it means that the highway runs in a south-north way *200-299 - it means that the highway runs in a west-east way *300-399 - it means that the highway runs in a diagonal way. Highways with odd numbers run northeast-southwest, while even numbers run northwest-southeast. *400-499 - it means that the highway interconnects two major highways. Often Brazilian highways receive names (famous people, etc.), but continue to have a YY/BR-XXX name (example: Rodovia Castelo Branco is also SP-280). See highway system of São Paulo for numbering designation for São Paulo state roads, also used in some other states. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brazilian Highway System」の詳細全文を読む スポンサード リンク
