[OSM-talk] Tagging bridleways

2008-05-14 Thread Nick Whitelegg
I've come across a problematic way near me: It is a reasonably wide 
road, but the signs at each end say it is a bridleway. 

I would guess this is a service road (i.e. leads to a few private 
residences/farms etc) over which runs a bridleway.

If this is the case I would tag as

highway=service; foot=yes; horse=yes; bicycle=yes

and maybe add motorcar=private though I don't really consider this 
essential.

This tagging scheme indicates that foot,horse and bike have access over 
the service road which they don't have over all service roads.

This will also allow the Freemap renderer to show the service road with 
the bridleway symbol (dashed red line) overlaid to indicate that you can 
walk/ride along the way.

It's not quite a 1:1 mapping - a UK bridleway also means cycles 
permitted by right and a whole host of other stuff, so it's a 
valuable piece of information in itself.

By all means tag the individual users (horse=yes, bicycle=yes, etc.), 
but I'd consider the official bridleway status a useful, taggable fact 
in itself.

What I'd like to get some idea of is what people as a whole consider 
highway=bridleway on its own(with no foot/horse/etc tags added) to mean - 
do people on the whole consider this to be a public bridleway, or a 
permissive bridleway? On freemap I assume permissive unless foot/horse=yes 
is added, rather like highway=footway is assumed to be permissive (in view 
of the large number of permssive footways in towns).

I generally only use highway=bridleway when the signs at the end of the
route say it's a public bridleway. Otherwise how would I know if it is or
not. However if there is some indication that it's a route suitable for
horse riders (eg an official looking horseshoe symbol) then I'll tag that as
bridleway too unless a higher usage is allowed.

I find it interesting that you use motorcar, as I generally just use  
car, as that is what I think is on the wiki (unless someone has  
decided to change it).

If I come across a bridleway sign, I'll tag it as highway=bridleway,
assuming that horse=yes is implied. As Andy says, how else would I know
it's a bridleway?

I generally find that footpaths in towns is an odd situation, some are
clearly regarded as public rights of way (some I've seen even having
full road name-like signs informing you of that [0]). Signing differs
wildly between london boroughs, Sutton having relatively few signs
(although an oddly signed bridleway down the back of houses[1] does
exist). On the other hand, Croydon signs every single one of the
footpaths I've seen with their own reference number and often a
destination - even if it's just the next road.

If something specifically informed me that it was permissive, I'd tag up
horse=permissive etc.

There could be permissive bridleway signs (prevalent in parts of Surrey) 
or evidence of horse use through it being a wide sandy track with horse 
prints. In the latter case, and in the absence of signs, I tend to tag as 
permissive bridleway.

[OSM-talk] Tagging bridleways

2008-05-13 Thread Steve Hill

I've come across a problematic way near me: It is a reasonably wide 
road, but the signs at each end say it is a bridleway.  It has a gate 
across the east end end so you can't drive along it from the east, but you 
can drive along it from the west end.  The west end has no restrictions 
other than a sign saying No Though Road.  There are a couple of 
buildings down there, so someone might have legitimate reason for driving 
along it even though they can't get out at the other end.

So I'm a bit unsure how to tag it - any suggestions?  Thoughts that spring 
to mind are either highway=bridleway, motorcar=yes or 
highway=unclassified.  Presumably with a highway=gate, motorcar=no 
node on the gated end, or maybe highway=gate, horse=yes, foot=yes.

This is an example of confusing the physical space with the legal
administrative description.

If it's a paved road from the end then unclassified, residential, or service
would be the appropriate tag for the physical. On top of that its horse=yes.
To add the bridleway specifically I would add bridleway=true as a tag as
well.

Just because it's a bridleway does not necessarily mean car=no. The
landowner will almost certainly have access over the route. Since it's a
bridleway however the public probably do not (unless its permissive).

Andy

Yes, but sadly the highway tag is defined in Map Features to encompass
that confusing mixture of physical and legal descriptions. :)

Yes it is, that's the one thing I wish I had thought of when I produced the
original list back when the dinosaurs were still roaming the land ;-)


(It is something we should probably try to move away from, but that's
another discussion).

 Just because it's a bridleway does not necessarily mean car=no.

The wiki indicates that OSM considers highway=bridleway to be a footpath
which horses are permitted on (I would think highway=footway, horse=yes
would be better and am in favour of getting rid of highway=bridleway
entirely.  However, I also want to be consistent with what other people
are doing.)

The wiki is not very cleverly worded then. Probably because its trying to
combine the physical description with the legal access situation.


 The landowner will almost certainly have access over the route. Since
 it's a bridleway however the public probably do not (unless its
 permissive).

In this case, I imagine the highway belongs to the National Grid, since it
provides access to the Swansea North substation and some of their offices.
However, at the west end of the highway there is no private, no cars,
etc signs, just a No through road sign (which makes sense since there is
a gate at the other end... probably to prevent people rat-running).  Also,
there are currently some roadworks on the highway, which are signed as you
would expect them to be if they were on a public road (the normal
red-triangle roadworks and blue-circle-with-white-arrow keep right
signs).

Maintenance of signs is often slapdash. Often signage is only added if the
way is being abused and the landowner wants to put a stop to it. A gate at
each end and a padlock usually gets over most issues, but in this case they
would need to leave access for bikes/horses/walkers if they did that.

Apologies to those who've heard me blether on about this before, but  
in my mind the highway tag indicates purpose. In other words: what's  
the way there for?

In the UK, at least, the administrative category (M, A-primary, A, B  
etc.) usually correlates pretty well to the purpose (in fact, one  
influences the other).

But occasionally there's a really glaring discrepancy between purpose  
and category. In which case, we follow the Oxford High Street Rule:  
tag for purpose, but make sure the administrative category is still  
recorded. (The High Street in Oxford is nominally the A420, so we tag  
ref=A420, but it's no good as a through-route - the bollards are a bit  
of a giveaway - so we tag highway=tertiary.)

Skimming the thread, your road sounds like highway=unclassified;  
designation=bridleway. Or something - finding a consensus for  
designation= is left as an exercise for the reader.

I'm left wondering why they haven't removed the A-road designation if they

horse=yes seems as descriptive as designation=bridleway.  I think I will 
settle on highway=unclassified, access=private, foot=yes, horse=yes, 
bicycle=permissive, motorcar=permissive.  I don't actually know the 
status of bike and car access, but the fact that it has been signed as a 
bridleway indicates to me that pedestrians and horses have a legal right 
of way along there.

Thanks for the input folks.
