While we're on the topic, should the W/E or N/S carriageways be labelled as such, or should both sides have the same road name?

Seems Google also has incosistent markings, look at this map http://maps.google.com/maps?q=51.001380 ... 26157&z=16

The A272 is just a normal road at this point with traffic lights etc and 30mph speed limit yet is still marked the same as it is outside of the town where national speed limit applies!

This is area where we can make the Waze mapping better than other sources, and is why area managers are local people - the people who know the roads best are the people who use them all the time.

So far we have the following labeling for the UK

Freeway -> Motorway
Major Highway -> A roads outside of town
Minor Highway -> A roads inside town/ B roads outside of town
Primary Streets -> B roads inside town
Streets -> Local roads
Ramps -> slip roads onto Motorways and A roads

Is this everything? and is this the correct summary?

I think as general guidance that seems ok, although it should be used as guidance only and should be used in conjunction with common sense and local knowledge (for example there are a wide range of different levels of A-road - using York as an example again, the A64 running past the South shouldn't be at the same level as the A1237 going round the top). If others feel these should be strict rules I'll happily change how I do things!

These roads are usually narrower, and out of the highway types, they will usually be the last option for routing.

Based on this, I would say that a lot of A roads are in fact minor highways (I had an A-Road around York marked as minor, but someone changed it to major - I didn't want to start an edit war!)

agreed - good guidance, to be used with personal judgement where appropriate.

Looks good. It means a few changes to how I currently label things. Unfortunately I don't have time to rename all the roads I've done so far (at the moment), but I'll use those conventions for anything new.

Abbreviations are mentioned (I'd previously put the full name in for completeness). What about Street->St?

Basically that's how we do it in Belgium/Netherlands/Germany/(Italy?), with some little detailed difference:

Major highway -> Numbered road outside vicinity (or inside <40mph)
Minor highway -> Numbered road inside vicinity (or outside >40mph)

Outside the built up areas, I would be in complete agreement that A roads should be "major highways" and B-roads "minor highways" - but in the middle of London, A-roads are little better than most side roads...surely?

Yes, but it gives a much better view at the higher zoom levels. Normal streets disappear quite fast, whereas highways stay visible. So even in the city you really should make a difference between streets and highways. Speed is extrapolated from the average speed on the road, not by road type.

That means when you have an A-road with a roundabout, you would have to make the roundabout a ramp.
