Just don't give a name to the small ways between the left and right streets. It's not part of either road on both sides anyway. I can see this being awkward for routing: Continue 5.0 miles east on Sunset Boulevard to Cross Street , then continue 60 feet east on unnamed road to Cross Street , then continue 2.5 miles east on Crystal Ave to destination. If you break it in the middle between the two sides of Cross Street (or at either side), or if you bring them together at one intersection, the router can combine the segments with the same name or won't have to, and you get: Continue 5.0 miles east on Sunset Boulevard to Cross Street , then continue 2.5 miles east on Crystal Ave to destination. -- Alan Mintz alan_mintz+...@earthlink.net ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

As far as accuracy, I was referring to it being a single intersection of roads topologically, governed by a single switching strategy - that a single node (or polygon) is more topologically accurate than 2 or 4 nodes. -- Alan Mintz alan_mintz+...@earthlink.net ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Seems like the best way to go - easy for routers to simply ignore really short unnamed ways.

[Tagging] Ways that change names while crossing divided roadways
I installed the Garmin OSM map for my area and have been using it while I drive around locally. The one thing I've noticed is that there is a lot of inconsistency in how streets that cross divided roadways are named. For example: http://osm.org/go/Wpz_F8RFl- Note Sunset Blvd on the left and Crystal Avenue on the right. Crystal crosses all the way over to the left roadway. As a result, going south down the divided roadway, the Garmin picked up Crystal as the cross street, when I think it probably should have picked up Sunset. I'm thinking the solution would be to split the small way segment between the major roads so that the naming can carry across the major roadway. Make sense?
