<div class="moz-cite-prefix">The situation in Scotland came about
after comparing OSM's motorway and trunk network to Transport
Scotland's official list of trunk roads.

<div class="moz-cite-prefix">There were some mismatches and it was
discovered that a few A roads had been tagged as trunk in OSM due
to green signs - however there were also (usually newer) white
signs present on those roads (e.g. the A697). Given the
discrepancies, it made sense to set these roads as highway=primary
in OSM, basically deferring to the Transport Scotland list to
avoid confusion.</div>

The Scottish OSM maps already have their strategic routes as
trunk, with all other A roads as primary, which more closely
follows OSM terminology.
<div><br>
England-Scotland border (West to East) - 2 changes at the
border (A7 and A68)<br>
* M6 Motorway<br>
* A7 primary route (Scotland strategic, England non-strategic)<br>
* A68 primary route (Scotland strategic, England
non-strategic)<br>
* A697 primary route (Scotland non-strategic, England
non-strategic)<br>
* A1 primary route (Scotland strategic, England strategic)<br>
<br>
Changes of designation at borders are not unusual, so I'm not
concerned about that.<br>
<br>
The only real downsides to this proposal are the work involved
(which shouldn't really take too long) and the loss of
information about which roads are designed as primary - which
is a bit of a false distinction in any case as primary routes
do not indicate the actual standard or importance of the road,
just that they link two 'primary locations'. Note that
'primary' locations do not mean they they're actually
important locations, just that they're useful for navigation
purposes (e.g. Scotch Corner as a junction, and Stevenage for
itself and the towns around it). The use of those locations
for navigation purposes made sense in the 60s but with satnavs
etc the standard and relative importance of the road should
take priority on maps.<br>
