To be a bit more specific about it:
All access tags follow the pattern: transport mode = access value All the different transport modes form a tree, as can bee seen here: https://wiki.openstreetmap.org/wiki/Key:access#Land-based_transportation “access” is the key used for the transport mode at the root of the tree. To find out the effective access value for a specific transport mode (a leaf node in the tree of transport nodes) you start at that transport mode and check if there is a tag defining an access value, if not, you go to the parent in the transport mode tree and repeat the check, until you either find a tag (which is then the effective access value) or you checked for the “access” tag (the root of the tree) and didn’t find it. So if you tag something as e.g.: access=no psv=designated and you want to know the access value for e.g. a normal car, you check: motorcar -> not found motor_vehicle -> not found vehicle -> not found access=no your effective access value for motorcar is no. If instead you want to check for bus, you check: bus -> not found psv=designated your effective access value for bus is designated. If you would tag something (very wrongly) as access=designated that would mean that any check that reaches the root of the tree would result in the access value of designated. Which makes the highway designated for every possible type of transport. And anything that's everything is nothing… From: Lionel Giard <[email protected]> Sent: Friday, 8 June 2018 19:30 To: Tag discussion, strategy and related tools <[email protected]> Subject: Re: [Tagging] Access=no for bus lanes Yes the idea behind access=* is a general tag - it indicate for every other transport types (except if another more specific tag is used) : so access=private just say that for every type of transport it is a private access, and if you add foot=yes, it became "private for everyone except people on foot that can walk freely). There is a hierarchy as shown on the wiki where a more specific access tag override restriction. 2018-06-08 11:25 GMT+02:00 marc marc <[email protected] <mailto:[email protected]> >: about "Bus-only roads" Le 08. 06. 18 à 11:00, François Lacombe a écrit : > highway=unclassified + access=designated + bus=yes + cycle=yes access=no + bus=designated (+ cycle=yes and/or taxi in some country) _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
