[Talk-GB] Feature Proposal - RFC - Change the meaning of the UK highway trunk and primary tags

[Mateusz Konieczny]

Note: this seems repeat of

I have no UK experience but some things that I spotted:

"Primary routes aren't the most important roads (as defined by government)"
"Stays consistent with UK OS maps."
"No central authority for routes. Data not publicly available."
Note that OSM is not obligated, required or needed to follow official classification.
Even in country where tag names may match official classification,

Especially "OSM classification differs from government classification"
is not a problem by itself.

> In the UK with standard of the core road infrastructure, it seems 
> unnecessary to have 30mph one lane single carriageways designated as 'trunk'.

Why it would be wrong?

> Small 30mph roads do not seem fitting of the criteria of "high performance 
> or high importance roads that don't meet the requirement for motorway".

Are you sure that this roads are not forming core network?
(in some places of world even unpaved muddy roads may qualify as
highway=trunk)

> both have similar physical features and carry similar levels of traffic

That does not automatically mean that the functional role in road network
is the same.

> Proposal a change to the UK OSM guidance for trunk and primary highway tags. This will allow for easier future maintainability by aligning the definitions with publicly available datasets, more closely align with global OSM terminology and also align with common UK terminology.

> The exact proposal will depend on community discussion and feedback.
