Also sure this reads number plates and isn’t just a basic traffic counter?

Typo ALNR?

Norfolk County Council often have phrase-like names for obscure things such as short footpath links that I tag using official_name key. However, those are from official source, so description/note probably best from OSM mapper point of view.

Perhaps replace name=[value] with description=value then.

Why the square brackets in name tag value?

The Aldeby village sign doesn’t have the text ‘Village Sign’ on it, so why did you change the name tag to that?

Great stuff.

Probably surface=bitmac if that is a footpath, a more specific type of asphalt.

There is that benefit I guess, but I just wish all the websites would update their logos and links for efficiency of user agent look-up. So long as the data is there all is good in some discoverable form, just as I've gotten used to sidewalk/soccer terms.

Weird how auto-correct is contact:x to contact:twitter, the old name, the auto-redirected domain, that is falling out of common use, and near totally in media broadcasts.

Why not highway=path and foot=yes, if these are not properly established routes? What is the surface?

Was the reference not amended to include suffix 'D'?

This is one of those exception cases I think as it is the main route from A47 to the village of North Pickenham itself - despite being narrow as is rather typical of most rural Norfolk roads. Many are tertiary grade, salted as priority routes, etc.

This is still a legal, council prioritised tertiary grade road - even if the maintenance of it is poor. Please consider reverting to tertiary.

Curious definition of dual. Implies two roads, parallel to each other. Both Department of Transport and Council Speed Awareness course instructor confirmed to me that on-slips are national single carriageway limit, up to the point that the grass separator ends and they become the dual carriageway road. Doesn’t stop everyone going faster than that of course. Official stance is that merging at 60 mph is closer and therefore safer to average traffic speed of lane 1.

One technicality to mention though is that once an onslip itself no longer has physical separation but forms part of one continuous road surface of the main parallel dual route then it can be considered 70 mph, generally parallel enough by that point too to meet the legal definition.

I'm not sure they can be called expressways either, since cyclists, pedestrians and even horses are permitted.

This wasn't a correction, but a degradation in OSM data quality. If you contact Department of Transport, or any Speed Awareness Course leader you’ll be told that dual carriageway (not motorway) on/off-slips in the UK are treated as a single road just like any other single carriageway, and so in law remain 60 mph for safety blending with main expressway traffic. Commonly broken law, admittedly.

It seems Southampton council don’t have a good understanding of common law, or they have curious by-laws for their particular jurisdiction. It has affected your judgement. Never assume councils know what they are talking about, or that their data is up-to-date or complete for that matter.

Roads can be adopted, or unadopted, and at the same time either publicly or privately-owned.

In this case from NSG:
USRN: 4600057
ABELS CLOSE, FELTHORPE
Classification: Neither M, A, B or C
Responsibility: Not maintainable at public expense, Private Street Manager.

You also appear to reject the existing wiki article specifically mentioning 'for residents only' access being treated the same as access=private.
