Duane/Harald, At Telenav we have been ‘signposting’ (adding destination tagging) for the last 6+ months. Using Martijn’s post as a template, we have used the exact syntax Harald shows in the example.
I am reading with great interest the post at: http://wiki.openstreetmap.org/wiki/Exit_Info. Bifurcations with multiple exit numbers are complex (see US Examples: A/B Split Example). Adding the junction:ref on the WAY has merit. I am still digesting the method and looking for other examples.

I created a wiki page that has some of the proposed improvements for the categorization of the exit sign information. http://wiki.openstreetmap.org/wiki/Exit_Info Tagging the exit sign information as suggested will improve the route narrative at these highway transition points Martijn van Exel has also be advocating for better US exit sign tagging: http://www.openstreetmap.org/user/mvexel/diary/22419 My suggestion for the off ramp would be: destination:ref=I 39 South;I 90 East destination=Janesville;Chicago Regards, Duane On Tue, Mar 3, 2015 at 10:28 AM, Harald Kliems <kli...@gmail.com<mailto:kli...@gmail.com>> wrote: I recently captured Mapillary imagery along I-90W between Madison and Wisconsin Dells with the aim of adding destination tags to exits. The example section of the documentation in the wiki [1] only has German signs, which is not that useful. I'm wondering how people handle the highway destinations commonly found on signs. For a somewhat complex example, take this sign: http://mapillary.com/map/im/lE5ZLUjfn-gTLB51nnh9fg (Not that for some reason the Mapillary has an offset for the location of the images; the actual location of the sign is about here: http://www.openstreetmap.org/?mlat=43.10188&mlon=-89.28977#map=18/43.10188/-89.28977 ) So for the left part of the highway I tagged destination:lanes=I 39 North;I 90 West; I 94 West;Wisconsin Dells|I 94 East;Milwaukee For the off-ramp: destination=I 39 South;I 90 East;Janesville;Chicago Questions: - the wiki page seems to imply that the various interstate references shouldn't go into the destination tag. That seems wrong to me, as I'd expect a router to include them ("Take the exit towards I 39 South, ...") and don't see where else they would reasonably go. The wiki (first example) says "Additionally it is possible to set ref=A 2 on the highway=motorway." -- not sure what that means. - The ever-recurring abbreviation question: Do I write out "Interstate" or not? Abbreviate north/south...? I have the suspicion in some cases that would lead to exceeding the 255 char limit. If using an abbreviation, we don't use a dash between I and the number, and a blank between the number and direction, right? Thanks for your input. In case there is consensus (one can dream!), I'm happy to update the wiki with some more US-specific examples. Harald. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org<mailto:Talk-us@openstreetmap.org> https://lists.openstreetmap.org/listinfo/talk-us
