[Talk-GB] highway=primary cul-de-sac?

[Nathan Case]

Agreed. We map roads by its function, not by its reference number.

The current reference/classification is clearly related to the previous function.

It's an usual case but, based on its current function, the road is clearly residential.

For me it is definitely not highway=primary, though if it is officially classified
as primary road in official designation data for UK that makes it a bit tricky.

Is it fine, also in UK that gave origin to main highway=* values, to ignore
official road classification where it is silly/outdated?

Poland has relatively highly classified road that is 55m meter long and leads to
an abandoned railway station ( https://www.openstreetmap.org/way/264203873/history )
https://pl.wikipedia.org/wiki/Droga_wojew%C3%B3dzka_nr_219

Also from Poland:

National road 58: https://wiki.openstreetmap.org/wiki/File:Jedwabno.JPG
National road 90 in 2010: https://wiki.openstreetmap.org/wiki/File:Korzeniewo12.JPG
(yes, ferry crossing)
National road 90 in 2013: https://commons.wikimedia.org/wiki/File:Kwidzyn_most.JPG
(rerouted a bit, old ferry was abandoned)
National road 81: https://wiki.openstreetmap.org/wiki/File:Miko%C5%82ow_-_DK81.JPG

Obviously, not all of them are classified in the same way.

(it is explicitly documented at
https://wiki.openstreetmap.org/wiki/Drogi#Klasyfikacja_dr%C3%B3g as it is common
mistake by newbies to reclassify sandy road across forest because it is officialy
classified as something)

I thought this was interesting: I noticed that a couple of mappers have different opinions about whether a road in OSM should be marked as "primary" or "tertiary". The road is still apparently designated the A3000, though Hounslow Council/TfL have also designated it a section of the route of Cycleway C9, and the last 300 metres are now a cul-de-sac (at least for cars travelling westbound, there's a modal filter at the end so pedestrians, cyclists et al can continue onward and there's also the one-way Clarence Road which allows cars to join Wellesley Road eastbound)

So is it still a primary road because of the designation? Can a primary road be a cul-de-sac? Aren't they usually roads designed to be a core route of the road network?

I'd argue that if anything, from a motor vehicle perspective, it's become "residential" rather than "tertiary"...
