The issue is mostly with how the current standard (as stated here

routing. This is said on the proposal page here "Many current routing
softwares add a delay to trip time when encountering the tag barrier
<https://wiki.openstreetmap.org/wiki/Key:barrier>=toll_booth
<https://wiki.openstreetmap.org/wiki/Tag:barrier%3Dtoll_booth>.
However, the delay on these more modern toll collection systems is
significantly less; not requiring the driver to stop in most cases.
In effect, this means that many drivers will be routed onto a slower
route.” This is the major difference. Of course the way itself should
be tagged toll=yes. This is a clean way to a) show where the toll
begins and b) give the routing software something to account for on
the way.
First, how much of a delay is added by the routing engines, have you
investigated this? If so, this would be a few seconds once-per trip,
not every 500m like a traffic light. Thus the difference on the
calculated overall travel time would be insignificant.
An old toll both was where I'd have to stop, dig out some money, hand it
over, wait for any change, then I could go on. 30 seconds to 1 minute
unless I drop the money.
I think these are all gone now on highways and bridges. They still exist
and are in use for some National Park entries, possibly some parking
places.
Second, the problems described would be more easily and more elegantly
solved with subtagging the existing barrier=toll_booth, instead of
inventing a new first level tag. Subtagging preserves backward
compatibility, while a new tag has to be implemented everywhere,
But a toll gantry has no stopping, nor slowing down. A very different
beast, with the ones around here the vehicle is meant to have an
electronic device that the toll thing responds with and the payment is
deducted automatically. If you don't have one of these electronic do
dads then you get a letter .. with a higher fee. Don't know that "toll
both" is how they should be tagged from a human conceptual view point
rather than the practical computing one.
