Talk:South African Tagging Guidelines
What about highway=tertiary
Can we find a place for it? Firefishy 17:13, 28 March 2007 (BST)
In Pretoria Central, we have the R101 (Paul Kruger / Potgieter / Schubart), the R104 (Church), the M1 (DF Malan), M2 (Skinner), the M3 (Nelson Mandela) and the M4 (Schoeman and ?). So strictly adhering to Adrian's scheme will result in one not being able to follow the routes. -- Nic 17:48, 20 May 2007 (BST)
- Not able to follow the routes? What do you mean? We have the tag ref=<route number>. We can distinguish the different types of road that way. The highway tag is supposed to indicate the quality/size of the road, not the legal status. "motorway" is the same thing as "freeway" (just the British terminology, where we have the American). Not all freeways are national roads, nor are all national roads freeways. The fact that the freeways are rendered in blue is, of course, a coincidence. - Htonl 21:04, 27 September 2007 (BST)
- I mean't they're all the same colour, hence difficult to follow. -- Nic 19:21, 24 August 2008 (UTC)
I think the whole system should be changed Motorways = all roads designated as a freeway Trunk = N routes (N1 to N18); Primary = Low number R roads ; Secondary = High number R roads; Tertiary - all other tar roads ; Unclassified - gravel and other roads; chris11 25 September 2007
I wouldn't agree entirely with that entirely:
- Making trunk for N roads only - not opposed to that change; I was worried myself about N and low-number R roads being classified the same.
- M roads need to also be classified in primary/secondary - they are not all as small as tertiary roads.
- Not all tar roads should be tertiary - look at Map Features for more, but, basically, "ordinary" side streets in the city or the suburbs, for example, are "unclassified" (or "residential" where appropriate) - definitely not "tertiary".
I'll apply the changes to the page. - Htonl 21:04, 27 September 2007 (BST)
Agreed - narrow tar roads with no centre markings etc should be unclassified and not tertiary.

Could we include tracks in the list? South Africa has a lot of farm roads, "Jeep" tracks, roads that don't even have gravel, informal settlement roads, 4x4 recreational roads and roads that are in such a bad state of neglect that 2 wheel drive vehicles cannot use them (like Baster Foetslaan Pass which will likely never be repaired).

Proposed alternate tagging scheme
I propose an alternative scheme that focuses first on defined routes. A route (e.g. N1, R101, M1) would have its highway=whatever tag for the entire route even if the road type changes. Routes are what people reading a map are really wanting to see. The actuall physical road type, i.e. freeway, residential, etc is not want people need most from a map.
|National routes (N roads)|| highway=motorway
|The primary national routes connecting the country together.||N1, N2, N3, N6, N12, N18|
|On/off ramps to N roads|| highwayMotorway_link
|Where access is limited to special connection roads.||On ramps|
|Regional routes, major (R1 to R99)|| highway=trunk
|Major routes off the national highway network.||R27, R43|
|On/off ramps or slip roads for above|| highway=trunk_link
|Where access is limited to special connection roads.||Off ramps|
|Regional routes, minor (R100 and greater)|| highway=primary
|Minor routes off the national highway network.||R101, R326|
|Metropolitan routes (M roads)|| highway=secondary
|The major roads within a metropolitan area.||M3, M12|
|Roads linking cities or towns that are not part of above routes||highway=tertiary|
|City/town streets not part of above routes and with residences||highway=residential||Roads where people live.||Roads in suburbs|
|Roads in parking lots|| highway=service
|Large parking lots (not road-side parking)||Parking areas at shopping malls|
|Driveways, private access roads and similar||highway=service||Usually short roads just to get to some private area||Access to an industial complex|
|City/town streets, all other||highway=unclassified||Other metro roads||Roads in business areas|
| Roads in informal settlements,
farm roads, unpaved roads through game parks,
recreational unpaved roads or
any rough surface road that doesn't fall under anything above
|roads in some townships|
