There is a philosophy in some parts that the roads of a particular class should form a continuous network with other roads of that class or higher, with no 'dead ends'. So primary roads should link to other primary roads or to trunks or motorways. In UK terms, highway=residential is equivalent to highway=unclassified with the additional attribute of having housing along it. So in theory, this link road could be considered highway=unclassified.

On the other hand the wiki at https://wiki.openstreetmap.org/wiki/Key:highway#Link_roads consistently associates _link values with the higher of the two classifications connected, so primary_link is correct for linking a primary to a residential road.


Basically, these two philosophies are incompatible, and you're entitled to choose whichever one you prefer. And therefore to ignore any Osmose errors that do not apply to your chosen philosophy.

Hello,

Osmose reports an error with reason "Bad topology way level 2" [1] at this place [2] and I don't know how to resolve it.

There are no buildings around that piece of highway (I'm talking about the small segment of road, not the residential or the primary highway around) and its sole purpose is clearly to link the primary and the residential road.

So, according to table on the wiki page [3], it should be tagged as primary_link, but then Osmose reports a topology error.

Am I missing something ?

How would you tag it ?

Thx.
