Ah; I looked at this and saw a different problem. I'm used to a satnav that doesn't know exit numbers. All it says is "take the exit on the left." And that can be confusing when the road signs consider that direction "straight". Both cases you gave could have this problem, since we can't use the highway=* tag to determine which way is "straight" and which way is "left/right". Anyway, to address your problem, destination sign relations would definitely help. The satnav may still say "left" when it ought to say "straight", but it would be able to give a name for the driver to follow, which is probably more helpful anyway. Ideally *every* exit would have multiple DS relations for everything that's labeled at that exit, but it will take us a while to get there. -- Peter Budny \ Georgia Tech \ CS PhD student \ _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
