here are two real world cases that are on my mind: 1) access to the Biltmore estate, Asheville NC we were down in the area over Christmas, and toured the mansion on the 24th. we tried using the Skobbler app on my iPhone for routing, and got led seriously astray. the tagging needs to be improved, but it's unclear what the correction should be under the scheme as it exists now.
the situation is that the land for the state is quite large, and there is more than one road in; however, only one road is appropriate for tourists. all the roads in are gated and private. but if you tag them all access=private, then the router has no way to tell what the correct road to use is. we were led to a gate on the backside of the property that was clearly labeled as not being for access to the complex. it seems to be a common problem in the GPS era as there was a sign directing us to the correct entrance. i suppose OSM could use access=permissive for the preferred route, but that usage doesn't match well with the current language for permissive. 2) access road to Palmer Motorsports Park. this is a little theoretical since Palmer won't open for business until mid summer, but Palmer has an access road which will probably have some sort of security on it (and thus have access=private). there is a public road into a wildlife area adjacent to the track, which i've seen OSRM use for the endpoint, ignoring the actual track access road. again, some sort of tagging tweak seems needed if we want routers to do the right thing. deliberately not using service roads when they are actually the correct roads to use is a problem. richard -- rwe...@averillpark.net Averill Park Networking - GIS & IT Consulting OpenStreetMap - PostgreSQL - Linux Java - Web Applications - Search _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
