A couple of questions about C-roads...

Is there a consensus about how these should be treated? Given that they

C roads are marked as yellow on OS landranger maps.

No idea whether c-class road references are nationally unique. It seems both
plausible and implausible at the same time.

I don't believe they are - in fact each authority has it's own numbering

both plausible and implausible at the same time.

The C-numbers seem to low (1000) for them to be national.

You'd probably end up with 6-figure C roads if they were nationally 
numbered...

Also Kent isn't in region 3 for road numbering (between the A3 and A4, 
i.e. Wessex and southwest England) which would mean it's unlikely to be a 
national scheme.

If this information is available then its useful data within OSM in the same
way that references to gritting routes and customary bus stops are useful.
However, because these things are difficult or impossible to verify on the
ground its doubly important that if they are added to the database they
include appropriate source tagging.

I certainly would not encourage changing the highway= tag just because the
local authority has referenced the road as C, D or U. Just treat the detail
as additional useful information to someone, not necessarily the OSM
rendered map.

Cheers

Andy

At the top of the KCC Gazetteer it says:
National Convention for Road Numbering:
`U' stands for `Unclassified'
`P' stands for `Private Street'

So it appears there is a national convention, implying that authorities 
are not obliged to follow it. It might exist as a formal document, but 
it might be just a de facto convention. Uxxx appears to mean explicitly 
unclassified whereas a Cxxx or Dxxx road is not unclassified - it's a 
C-road or a D-road.

No. That would be tagging for the renderer. Even if it's generally a
non-visible ref in the outside world (though I've seen three C-roads leak
onto signs in my travels) I believe that it's the render's choice as to
whether they should show up on the maps, not for us to say that there's
something special about the fact. A fact's a fact.

 Secondly, am I right in thinking that these are not unique references
 like the A- and B-roads? (Unique within the UK, that is.) In other

I'm not sure whether they're nationally unique references, but they'll be
unique per authority and we've got pretty good bounding areas for those in
OSM now.

 Another use of this Gazetteer is to arbitrate between road classes,

 goes through the village still retains the C classification, and the 
 relatively enormous bypass is still unclassified.
 
 It occurred to the cynic in me that the lengths of roads of various classes 
 might be fed into some spreadsheet in Whitehall to calculate some kind of

 administrative classifications as high as possible, despite downgrading 
 them on the ground. But that's unlikely to be true of course.
