[Talk-br] Road network improvements in Brazil

[Fernando Trebien]

I forgot to mention, there was another interesting forum thread
regarding the classification of trunks in the entire country. While
most mappers agreed we need to raise at least some primaries to the
trunk level, there hasn't been consensus on the exact criteria that
should be used. [1][2]

Also, there is an undocumented (but openly discussed [3]) agreement
that the definition of motorway should be slightly relaxed, since many
highways fulfill the international criteria without fully implementing
access control.

My team is interested in doing some work on the road network in Brazil on OpenStreetMap, things like adding missing roads, making sure roads connect properly, fixing incorrect alignments with GPS traces, ensuring road classifications are consistent, and other similar issues.

Also I saw these guidelines about road classifications, are they the most recent classifications used by the community, or are there any others we should be aware of? https://wiki.openstreetmap.org/wiki/Pt:How_to_map_a
