The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Brazil, for both new street additions (left) and the aggregate street network (right).
Brazil in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Brazil followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Brazil, we can consider three of its most populous regions: São Paulo, Rio de Janeiro and Minas Gerais. Out of the three regions, São Paulo does not follow the same trend as the country. The level of street-network sprawl in new development in São Paulo rose steadily.
How do development practices in Brazil fare in comparison to others in the world? Most recently in 2006-2020, street construction in Brazil was the 40th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has fallen; relative to other countries in the world, street construction in Brazil has become more connected. Brazil ranked 39th in 1975, 49th in 1976-1990, 41st in 1991-2005 and 40th in 2006-2020.
The largest city in Brazil is São Paulo, with a population of 19180500 people. Taking into account the entire (i.e. aggregate) street network in São Paulo as of 2020, the overall level of street-network sprawl is 2.8, which is relatively well-connected. The level of street-network sprawl in new development in São Paulo rose steadily.
Brazil in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Brazil is Tefé with an SNDi of 8.34, which is very sprawly. Conversely, the most connected city is Tramandaí with an SNDi of 1.19, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Tramandaí, Tefé.
The level of street-network sprawl in the aggregate network in Brazil rose steadily. To get a sense of how the aggregate street network has changed in Brazil, we can consider three of its most populous regions: São Paulo, Rio de Janeiro and Minas Gerais. Disconnectivity in the most populous cities in Brazil follow the same country trend.
