[mkgmap-dev] question about ignored no_u_turn restriction

Sun Jul 5 10:34:13 BST 2015

Hi everybody,

I recently noticed a bunch of warning messages about ignored no_u_turn
restrictions. Here's an example:

2015/07/04 18:12:50 WARNING (RestrictionRelation): 17244023.o5m: Turn
restriction (no_u_turn) http://www.openstreetmap.org/relation/4630872 (at
http://www.openstreetmap.org/?mlat=41.890540&mlon=-87.805101&zoom=17)
no_u_turn with equal 'from' and 'to' way and via node is ignored

Looking at the rules for restrictions and the relation itself, I can't see
what the problem is.

http://www.openstreetmap.org/relation/4630872

Does anybody know why this particular restriction is being ignored?

Thanks, Ben
