This is deja-vu

About 5 years ago this exact discussion happened with the contributors to openstreetmap. Have a look at http://wiki.openstreetmap.org/wiki/Sout ... Guidelines where the final conclusions are. Openstreetmap has more classifications of roads than Waze


My take - Freeway means access via on and offramps. Might be dual carriageway. eg Platinum highway
Major Highway are the N roads
Minor highways are the R roads and can be tar or gravel (Waze is set up for the first world)

What about this one - Here the R512 changes from a Primary Street to a Minor Highway. Would major highway not be appropriate for both?

I note Major Highway is not used much in the Jhb area

I think the road type need not "look nice" on the map but should be telling the Waze user which road is better that the alternate.
My view is that we should use Freeway for all the proper designated freeways, eg the M1, etc as well as the National roads between the major cities. I agree that the freeway, highway, etc stops when you enter a town and should change to a primary street (unless of course it is still a freeway)

Major highways should be multi lane highways/well constructed, wide highways between cities/towns that are not designated as freeways. I would like these to be differentiated from minor highways that could vary from reasonable roads to ones where you might need to drive very slowly due to road condition.

Minor highways could even include good well maintained gravel roads but lets not go there.

I am happy to go with the SA road designators. That would make it simple, eg:
N and M roads are Freeways
Rxx are major highways
Rxxx are minor highways
primary streets are exactly that - the street you would use to drive right through a town or suburb

This of course clashes with the thoughts of RodNav. As I found out when the N2 between PE and Cape Town changes from a freeway to a major highway

OK - can we agree that N routes that are not double carriageway and have side road intersections without on and off ramps are changed to major highways?

Must admit my preference would be for Primary Street through the towns but that is not a very strong preference so I am happy either way

I think you will edit roads that are closed for a temporary period.

In the case of the Ght road I do not think it was really necessary to show the small detour as routing remains the same. The main idea of marking temp closures is to get the routing correct.

I bumped into this post trying to figure out why N12 long-distance routing is a bit dodgy.
Dodgy:
- U-turns as i enter a town, probably because main route is Primary and not Highway.
- Going through town and estimated time drops by more than a hour on re-route.

The above posts does not give a real answer . For long-distance routing to work it seems roads through a town should be major-highways ?

Example. (Going on N12 from North to South to George, Waze recommends u-turn back to N-10 as I entered Britstown)

Also found post referring to continuity in road types.

Is it a flaw / SA problem in waze that a route through a town can not be used for local routing and long-distance options ?
Maybe waze need a setting per country to search through smaller routes or connections.
