Yes, although there is sometimes a gate in the back with no regular
key card access (it might even be padlocked) which is not for regular
use.  It would be a shame if both these and those normal residents
only gates were tagged with the same access tags.

Although, now that I think about it, the best solution for routers
might just be to group sets of gates together with a relation, and let
users manually select which sets of gates they have access keys for.

There's still the one way problem, though.  I think oneway=yes is
probably correct, but the semantics of which way is which is ambiguous
(even if you say it's based on the underlying way, is it oneway=yes in
the direction the gate is locked, or oneway=yes in the direction it is
unlocked?)  I guess one hint would be that the access=private way
would tend to be on the inside rather than the outside.

Hmm...that just makes things potentially even more confusing though.
If the way is split at the gate node, then the two ways might not even
be pointing in the same direction.

 Granted, this does raise issues.  Besides the fact that oneway=yes on
 a barrier=gate is not well defined, there isn't, to my knowledge, a
 way to distinguish requires code or clicker which is given to
 residents from only accessible by maintenance personnel (and
 possibly emergency services).  And both seem to me to be a somewhat
 common situation.


IMHO the by far most often occuring situation are exit gates that can
be used only in case of an emergency (but then by everyone, not only

(emergency_exit).

The access tag on the road (the way) is separate from the access tag

Sounds like the ways are access=private, and nodes where the gates

oneway=yes.  I'm basing the oneway=yes from
http://wiki.openstreetmap.org/wiki/Barrier#Examples, though it's not

The parking lot south of C is for employees (and some special events, I 
believe). All the normal guest parking lots are south of A and B (the 
smaller ones are for the hotels, while the large one south of Seven Seas 
Drive is the only one Magic Kingdom guests not staying at a hotel can use).


A guest can enter at C, pass through B, and U-turn at the Car Care 
Center into the main parking lot. After leaving the parking lot he can 
go back north through the Car Care Center to the areas south of A and B 
(and head east on Vista Boulevard via a circuitous route), but cannot 
continue north to exit at C. So for guests the roads between A-B and C 
are de facto one-way southbound.

[Tagging] different access restrictions for different entrances to an area

This is the area behind the Magic Kingdom in Walt Disney World.

Signs going northbound at A and B say Service  Authorized Vehicles Only.

Southbound at C, a sign says Private Property / Walt Disney World 
Resort Guest, Cast, and Business Invitees Only.


(I verified A and C a few days ago; it's possible that B has changed 
recently.)


The exact tags to use for these are a matter of recent debate, and it's 
not worth rehashing that. But it's clear that they are different (a 
guest can enter Disney from Reams but can't exit that way), so for the 
sake of argument let's call the former access=private and the latter 
access=destination. Note that the area from A and B south to the 
beginning of the motorway is also access=destination due to the presence 
of the main entrance gate (and a sign identical to that at C on Vista 
west of Golden Oak).


The question is how the segments of road between these points should be 
tagged. Should the ability to U-turn be taken into account (thus 
everything but the close vicinity of A and B is destination in both 
directions)? Or should it be assumed that one won't U-turn for the hell 
of it (thus all three roads are private northbound and destination 
southbound)? Or should no_straight_on restrictions be used at the signs, 
with no access tags on the ways?

2011-10-25 Thread Stephen Hope
Have you actually driven through the roads, or just verified signs at
the entrances? From only looking at the map, I would expect that cast,
resort guests, business invitees etc can enter at C, but only to go to
the car parks right by the entrance, and further down that road the
restrictions would change to the same ones as for A  B. They would be
expected to exit by the same gate they came in.  I could be wrong, of
course, but I've seen that setup used elsewhere.

I've seen a similar case to the problem you described elsewhere,
though. There's a complex I've been to where only vehicles with a
key/transponder of some sort can use most of the entrances.  All other
vehicles have to go through the main entrance, which (usually) has
