These 3 roads (Hope St-Charlotte Sq-South Charlotte St) are classed as highway=primary but have no ref tag. The A90 ref tag ends at the junction of Queensferry St and Hope St. Is this correct or does the A90 carry on to Princes St via this route ?

Can't see any road signs to confirm either way.

Note: This route from Queensferry St to Lothian Rd can only be used by private vehicles when going north to south. There is a bus-only restriction from Hope Street to Queenferry St so private vehicles need to take a long diversion to go in the opposite direction.

The west & north roads around Charlotte Square are tagged as tertiary though the junction at North Charlotte Street is only open to buses, taxis and bicycles (buses/taxis can only turn left). Tertiary is for "busy, unclassified through roads" which this is not. Perhaps 'unclassified' is a better definition - "lesser importance than tertiary". Also not sure how this fits with the new tagging of Shandwick/Princes Street which now look more like tertiary roads to me ?

The turn restriction on the junction with NCS also needs to be corrected.

Can any road experts verify my understanding and/or update ?

Propose that we remove West Edinburgh, South Edinburgh and North Edinburgh suburb nodes as don't think these names are used by locals. Can replace the first two with suburb nodes for West End (further east) and Southside instead.

Saughton is defined as both a neighbourhood and a suburb - both centred around here. Does this make sense - or do we need to drop one of these ?

Blackhall is defined as a suburb under two different ways - id= 256067242 & id=256067243. They are marginally different areas. Can somebody decide which of these is more correct ?
