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?
[...] 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.

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. 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.

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.
