Aproveitei esse retorno da DF-290 (entre Valparaíso do Goiás/GO e Santa Matia/DF) para treinar, já que as correções ainda não são o meu foco do OSM. Ainda pode melhorar, com o JOSM (que não utilizo).

Just wondering, is it possible to go from the lower primary road into the tertiary road?
Because, given the current oneway restrictions, this isn’t possible on the map.

Não classifiquei as estradas, mas apenas o ajuste no design. I did not do the classification of roads, but only fit in the design.

It looks like you can turn from the DF-290 (travelling east) onto the yellow road. Also you should be able to turn from the yellow road back on to the DF-290 travelling east. Currently this is not possible with Ivaldo’s design. Obviously some one should check this with a survey :-)

Okay, thank you. You can see on: http://www.openstreetmap.org/edit?editor=id&relation=334496#map=19/-16.04900/-48.00430

Looking at the design of the roads I doubt it is any link between the eastbound primary and the tertiary since both eastbound and westbound primary are high speed multilane highways. If your desire is to get from the eastbound to the tertiary than you would probably need to continue to the next return, and coming from the tertiary to the eastbound you would probably need to follow westbound to another return. Of corse there might be signs on the place allowing for a direct connection but that must be surveyed properly before entering.
Remember that OSM routing should be legally correct so even if it is costume to cross directly but signs on the locale indicates this is prohibited or unlawful, our tagging should follow the legal routing to avoid louring a traveler doing something criminal.

Hi Skippern,
Access to tertiary road to DF-290 occurs in the east-west direction. But if the driver wants to cross to go from west to east, do so at their own (risk). He will have to assess as the road allows it (and not the OSM design).
Moreover, my speech is given only in design (set).

That was partly my point with the comment, the user is always able to break the law and assess his passage on his own risk, the routing should assist people not familiar on the place to arrive safelu and quickly on their destination.
