What about oneway:psv=-1, instead of massively overloading the access:
namespace? Okay, sorry for carrying the access namespace discussion onto the
mailing list...

Re: [OSM-talk] Almost one way streets

[Gregory]

Just as an interesting side note I was mapping an area today that looks like
the following.

a b
|  |
|--c--|
|  |
d e

c is a short oneway road to a-d, with two lanes (as if it was coming up to a
busy junction with lights, but it's an infrequently used residential roads)
b is a two way road, but it can only turn into c and not into e.
e is also a two way road, but you can only turn into c and not b.
b, c have the same name but that's different to e (c and e actually seem to
have equal priority as they turn into c).

So I tagged c as one way, and split and end section of b to tag it as one
way doing the same to e. That way the arrows should clearly show you can't
go from b to e or vise-versa.

For anybody very interested, a-b is Cardinal's Walk, c-b is Warwrick Close
and it should be on the map soon.

I just thought I'd share as it was a bit unusal and no apparent reason for
it. I guess to stop the residential roads being used as a cut through for
the A-road and junction that wraps around a-b-e.

For the "simple" oneway tag, -1 is used to indicate a contraflow lane.

perhaps:

access=highway
oneway=yes
access:psv:oneway=-1

There's no official tag for it.  It would be nice if there was, there's 
a three-block section of one street here that is three lanes oneway for 
the public, and one lane opposite for buses only.  I think I'll use 
psv=opposite for now.

If the only restriction is an access restriction at one end, is the street
one-way?

What's to prevent someone turing round in the street and travelling in the
"wrong" way? or exiting premises on the street and travelling in the
"wrong" way?

If such a street were in the UK, then I'd not expect it to be one-way just
on the basis of an access restriction at one end.

I hade some how manages to miss that one, it sounds close enuff to what I need.

One reservation thow, there are no signs informing that the street is
one way, it is only one way becouse of the accress restrictions at the
other end.
The potaintial danger I see with this is, one looks at the map and
sees that one need to turn right on a one way street, and then the
street have no one way sign, one might get confused. But it cude just
be me, so feel free to ignore this =)

The same should be possible for buses/public transportation/taxis. Is it?

I also think there should be a separate access restriction for taxis, 
sometimes it differs from other kinds of public transportation.

On the map features page [1] a tag is given that allows cyclists to 
access a oneway street from the restricted end (cycleway=opposite).
Below is an example of a such a oneway street:

highway=unclassified
oneway=yes
cycleway=opposite

Looks like  cycleway=opposite_lane would be apposite.

highway=
oneway=yes
cycleway=opposite_lane  - lane in the opposite way (a "contraflow" 
lane) 
OR
cycleway=opposite_track - track in the opposite way (that is, separate 
from the road) 
OR
cycleway=opposite - no lane or track marked

Here's the one I'm talking about:
(the road the 'a' marker is pointing to)

http://maps.yahoo.com/#mvt=s&lat=47.655889&lon=-122.318004&mag=1&q1=47.655383%2C-122.317634

The north lane (westbound) is for car traffic, the south lane has 
painted bicycle logos on the roadway, and is blocked at either end.  On 
the west end, it's by an island.  On the east, by bollards.

I would like to know, too, as there is one street in my area that is 
one-way for cars and has a separate two-way lane for non-motor traffic 
(bike, rollerblade, etc).

oneway=yes
cycleway=opposite

?

http://wiki.openstreetmap.org/index.php/Map_Features#Cycleway

"just permitted to cycle in the opposite way (one way street except for 
cycles). Note - such streets are common in Belgium, the Netherlands and 
Denmark, for example, but are rare in the UK (although they do exist): often, 
instead, actually the street is two-way as normal for its whole length except 
for the very short section past the no-entry sign at the end, where cycles are 
excepted from the no-entry by means of a short lane separated by an island. 
This is called a "cycle plug". In some places this has been represented as very 
short oneway Way at the end with an adjacent cycleway, forming a little 
triangle with the road they join to."

I presume Mattias may be talking about roads that have restricted access. That 
is you can turn into them when on the same side of the joining road, but not 
from the other side of the road. We have a couple around here that this 
applies to during morning or evening rush hour only, to stop a queue building 
up when the on-coming traffic is heavy. So the joining road is not one-way, 
only access is restricted.
Was that the problem Mattias?

No, because they are one-way streets for cars, but not for
(man-powered) bikes. Those are common at least in the Netherlands and
Belgium.

Why are they different to one way streets? Because they don't have the one
way sign where you go in?
Then I would guess a short oneway segment/way at the end with the no-entry
sign. If you make it very short I'm not sure you'd be able to see the
directional arrow, but at least the data is there and route software could
see that.
