U-turn restriction via way instead of node
I remember that this was discussed some weeks ago, but I cannot remember if a final conclusion was reached. Certain types of these U-turn restrictions can be rewritten as only_straight_through. For instance, the only_straight_through relation on Itäkatu (southbound) also prevents a U-turn from Itäkatu (southbound) via Kehä I (east) to Itäkatu (northbound): at http://www.openstreetmap.org/browse/relation/32875 When ways have been split to opposing oneway lanes, a via node must be replaced with a via way, like this: http://www.openstreetmap.org/browse/relation/59928 However, mkgmap will not like it: 2009/10/25 21:53:00 WARNING (RestrictionRelation): Turn restriction 59928 (http://www.openstreetmap.org/?lat=60.21242&lon=25.08756&zoom=17) 'via' member 4775828 is not a node Can this kind of turn restrictions be represented in the Garmin format? Best regards, Marko

At this time, we don't know how to do that. It may or may not be possible, we simply don't know. Cheers, Mark
