vision, directing occupation and economic density in the territory. Another problem is the lack of directing the Union Budget towards infrastructure works, since there is no law that guarantees funds from the Federal Budget for works on highways and other modes of transport, depending exclusively on the goodwill of the rulers. Brazil even invested 1.5% of the country's budget in infrastructure in the 1970s, being the time when the most investment was made in highways; but in the 1990s, only 0.1% of the budget was invested in this sector, maintaining an average of 0.5% in the 2000s and 2010s, insufficient amounts for the construction of an adequate road network. For comparative purposes, the average investment of the USA and the European Union was 1% between 1995 and 2013, even though they already have a much more advanced road infrastructure than Brazil. The country still has several states where paved access to 100% of the state's municipalities has not yet been reached. Some states have 100% of cities with asphalt access, such as Santa Catarina, which reached this goal in 2014; Paraíba, which reached this goal in 2017, and Alagoas, which reached this goal in 2021. In states like Rio Grande do Sul, in 2020, there were still 54 cities without asphalt access. In Paraná, in 2021, there were still 4 cities without asphalt access. In Minas Gerais, in 2016, there were still 5 cities without asphalt access. As it is in the United States, Canada, and most countries in Europe, larger/wider highways have higher speed limits than normal urban roads (typically between and ), 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 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 -
