I would use _link only, if it really links between two different ways, maybe even of the same type. But here I think it is just one highway going through, so I would not tag it as link. I disagree, since toll plazas that have cash tollbooths almost universally give it signage analogous to weigh stations, rest areas and exits, which all use links. The only difference being the link into the toll plaza terminates into a link back to the mainline highway. The toll point itself has to be considered as a slow down - essentially and visually by the user and supportively by a router. Using _link for the non-electronic lane may irritate 'normal' routers to prefer the electronic toll lane - and that may lead a non-electronic user in a dead-end. (downward compatibility as a security fall back) In this case the router should discriminate the lanes only by access tags (see below) - but not by the highway tag itself. Since you're not allowed to use electronic toll lanes in most places (E 470, which lacks cash-only lanes being a notable exception) unless you've been given permission (and usually a tag, sticker or windshield dongle) to do so, it makes sense to mark electronic toll lanes past cash toll plazas as private. This has the effect of routers announcing toll plazas in advance for drivers that are unfamiliar with the area (and thus probably don't have a pass), while still being easy to ignore for folks who do have permission to go straight through without stopping. signature.asc Description: OpenPGP digital signature ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Name, ref and relation - as you may choose every lane to go on your (high)way, all of them belong to all lanes in my opinion. There's also a question of what access restrictions go on the high-speed lanes. OK, to choose the 'right' lane by routers, it is essentially to know - but to use them, you need special equipment, and I don't know, if that is different for different toll passages. (Or is EPASS an 'everywhere equipment/operator'?) If you need different equipment, this (or the operator) must be tagged - and must be configured for the router too! I do not know, if an access=electronic_toll (with a subkey electronic_toll=*) would be satisfactory. (How do/shall routers handle unknown access values? I hope/think as 'no'). Nevertheless - as long as a router cannot discriminate _all_ of the necessary informations, he can only warn about the toll point itself - and the user have to discriminate visually.

[Tagging] Best way of tagging split between electronic toll and cash lanes?
Many toll plazas now have high-speed electronic toll lanes. Tagging seems haphazard. As I see it, the choices are: *What gets tagged as motorway vs. motorway_link? *What gets the name, ref, and relation membership? Note that some plazas have the cash lanes marked like an exit: http://en.wikipedia.org/wiki/File:SR_417_University_Toll_Plaza.jpg while others have the cash lanes in the middle and the high-speed lanes as an exit. There may also be some where it's more of an equal split, with neither marked as the main route. So the question is whether to use motorway_link for what's signed as an exit, or to consistently use motorway for either cash or for high-speed. There's also a question of what access restrictions go on the high-speed lanes. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
