access=private means if you have permission, and it is reasonable for routers to assume permission on terminal segments. access=destination does not require permission. It means that anyone has a right to use the road if they choose to travel to a location that you need that road for. So (applying my local rules), if there were a highway=residential access=destination and I wanted to go to the last house on the road and knock on the door to ask them to vote for me in the next election, I could do that. But if it is access=private then maybe I don't have a right to do that. You are talking about a router with a human-entered destination, but the use of OSM is much broader. Asking the question: May I drive to this place, just because I want to, is different than overriding private for routing when the router is told implicitly that there is permission. Thanks to all for the locked=no examples. So a gate with locked=no is a physical object you have to interact with but it does not physically block access and should not be deemed, without access tags, to prohibit access. I am assuming -- but the wiki is unclear -- that access=private, tagged on barrier=gate means that all modes of travel have a right of access only with permission, and that access=private foot=yes means that all modes need permission except for foot which has a legal right to pass. With access=private foot=yes locked=no then it's clear that physical passage is possible for all modes. With access=private foot=yes locked=yes then it says that phsical passage is not possible and hence if people can walk around then it needs a way representing walking around. I realize there have been "but we can invent complicated bypass tags" but those seem to not interact well with existing data consumers and it does not seem we have consensus. Is that were we ended up? _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
