[talk-ph] bocaue / balintawak / toll gates + round abouts

[Ronny Ager-Wick - Develo Ltd.]

I'm fixing some things on NLEX, but I'm not so familiar in this area
(apart form driving past there numerous times).
Is this the Bocaue toll barrier?

I'm assuming this is Balintawak toll barrier:

I was playing around a bit with the Dau Toll Barrier, but I'm beginning
to think I might have made a bit too much of an effort here:

Is there any recommendation for how to deal with issues like this:
- what do we call them (toll gates/barriers/booths)?
- how to tag them so that GPS navigators will deal with them in a
sensible way?
- is it a goo idea to do like I did in Dau, extending the one way path
tagged "lanes=2" into however many lanes there are in the toll gate, or
is it better to keep it a single path and just tag it "lanes=n" instead,
positioning the path approximately in the middle?

The same goes for roundabouts. I've been quite accurate when making
them, letting the roads leading in and out enter the roundabout the way
the traffic normally flows (or is supposed to flow, if anybody were
following the rules), splitting them in two tiny one-way streets to show
the exact flow of the traffic in and out of the roundabout.
Is this a waste of time?
Should I rather just let the road go straight into the roundabout
without splitting it?

I'm trying to make the map usable for GPS navigation, but I'm not sure
if this is the best way to achieve that.
Any advice is appreciated.
