Hi,

What does lanes=2+1 mean?

Is this correct? or should we fix them whenever we see them? No information on this is available on the wiki page of Key:lanes.

The example is: This line

It is hard to be sure from the Bing imagery but it is possible that this should be a dual carriageway with 1 lane in one direction and 2 the other. Probably best to send a message to the mapper who tagged it like that to ask, if they're still mapping. Otherwise it probably needs resurveying to find out what it means.

Thanks. Any thoughts on this one where lanes=0 ? http://www.openstreetmap.org/way/231734622#map=19/58.75083/13.95682

No, it is a dual carriageway with one lane on each direction. The +1 is probably used for the zebras between the lanes. And physically, the lanes are in fact separated by a barrier which means that we could draw two separate lines in OSM with lanes=1.

@Aram Azhari ; look it is an error (based on mapbox imagery). If the amount of lanes is unknown, then better not use the tag at all.
