It makes sense to me to go more by physical attributes than the official primary/secondary/tertiary rating. Among other reasons, medium-term conditions such as construction projects may mean that the quickest route from point A to point B involves the use of a lower-rated roadway to bypass a choke point. -- John F.

Re: [Tagging] works_as_highway=primary
Hi Pavel, First let me say that I am totally against the idea of “silly tags” such as works_as_highway=primary. This just indicates a lack of understanding of the real situation. I have looked at your problem and understand what you are seeing. I will give you examples in the Czech Republic as that appears to be the area of concern. My case example is the D1 from Praha all the way to the border with Poland. http://www.rsd.cz/rsd/rsd.nsf/0/80345976071FCBACC12575CF004E133E/$file/RSD2009cz.pdf (Page 23) You will see that the D1 is incomplete from before Prerov to Ostrava. The cross-border European road network (E462) has chosen the D1 onto R46 onto R35 then back onto D1 as their choice of Primary Route. http://www.rsd.cz/rsd/rsd.nsf/0/80345976071FCBACC12575CF004E133E/$file/RSD2009en.pdf (Page 7) which shows that a Primary route does not necessarily mean it follows the route numbering of a country. You can also see from here that the Primary route bypasses Brno to the south and does not actually go through Brno and many countries countries have adopted this routing to avoid congestion and thus delays along their primary routes so Primary routes do not always take you into your destination city, town, village or hamlet. Where a Primary route is “incomplete” it does not mean that the road just drops off into a deep hole. The lesser roads are the Primary route and were the Primary route before the new planned routes came into existence ... irrespective of the alpha-numeric numbers allocated to them now just because they are not motorways or dual carriageways. So you are dealing with a multi-layered numbering system with EU on top of National on top of Local. The OSM classification irons out all those inconsistencies into a single understandable continuity and should show a continuous primary route along a route that changes from an international to a National to a Local or dual carriageway to two way hard top to a two way unsurfaced and in some countries down to a single lane unsurfaced road. It would be impossible to render all roads according to their National numbering, type of road and state of surface but we can tag them accordingly.

We try to render primary road overview in Czech republic, so the drivers could easily see where its possible to drive. But sometimes the primary road ends and continues as a secondary road - it could be in cites, or possibly temporary detour. (see links below) Is there any recommended solution already availible? Otherwise we have two solutions to discuss. 1) technically the small secondary roads part works as primary road network. So we would suggest a tag similar to works_as_highway=primary. Do you think its ok? Any suggestions? 2) less preferable solution would be to add render specific tag. Something like low_zoom_as_higway=primary.

Re: [Tagging] works_as_highway=primary
What I try to say is that you should not map a important road for large distances as secondary + works_as_primary just because it is a smaller, has a different surface, a different ref or whatever. Then (large distance, important road) it is a primary road IMHO, regardless of any other tags. If one downgrades such a road to secondary, the router can no longer prefer it over other (real secondary) roads. (as you wrote) Perhaps Ralph Aytoun expressed it better. But I tried to say the same as he. Of course we shouldn't tag secondary or primary roads as trunk road or motorways, but secondary primary roads should only be tagged based on their function, not on their appearance. regards m On Wed, Jul 29, 2015 at 1:11 PM, moltonel 3x Combo molto...@gmail.com wrote: On 29/07/2015, Marc Gemis marc.ge...@gmail.com wrote: On Tue, Jul 28, 2015 at 5:29 PM, moltonel 3x Combo molto...@gmail.com wrote: A router won't care about classification differences between far away places like Germany to Ethiopia.

I believe the term official classification is often mistaken or at least not thoroughly looked at. Often there is more than one official classification: visible and obvious is the maintaining entity, e.g. the country, state or municipality level, but what is not so well known and not visible easily is the conceptual level/class of connection roads (importance of connection) which together with the estimated traffic intensity and available funds and topographical setting and political processes determine the actual road that will be built (or enhanced). E.g. in Germany the official classification that most people are aware of is Bundesstraße (nationwide network) Landesstraße (state maintained network) Kreisstraße (Landkreis maintained network, slightly bigger than municipality) But if you look at the planning guidelines and standards you will see much more different types, e.g here: https://de.m.wikipedia.org/wiki/Verbindungsfunktion#Verbindungsfunktionsstufen there are ~categories (A-E, inside or outside of settlements, with or without adjacent buildings) ~levels of connection functions (I - VI, what does the road connect) The result of the combination of these 2 groups is the road class (e.g. B III), in theory 30 different classes, but not all combinations make sense. This is admittedly only the German situation but my guess is that many other countries operate in a similar way (i.e. do have more complex road classes internally than what is visible from signposted ref).

Sorry but no, too simplistic. A lot of local OSM communities follow the official national road classification where possible. For example in Ireland, any ref=Nxx road with xx51 is highway=trunk, and switches to highway=primary when xx50. http://wiki.openstreetmap.org/wiki/Ireland/Roads This makes sense because it is expected by any Irish driver and map user. While it does result in some road classification changes without any physical changes, this just reflects the administrative reality. OSM is a global dataset and following everywhere the same criteria to determine the highway tag is important for a smooth usage of the data across borders. That ideal doesn't match the practical reality. highway=primary has a very different definition between Ethiopia and Germany, by necessity. A global uniform standard for highway=* would be pretty unusable. But we do use a collection of local standards, so we have local consistency (hopefully at least at the national level), which is the most important thing. That said, there are plenty of tags other than highway that are usefull and objective: maxspeed, lanes, width, traffic lights, speed bunps, and even surface (but that one is getting subjective again). Go map them, in that rough order of priority. They are used by routing software and solve the OP's question for routing. If you want to use those tags for rendering, talk to your map style developer (you'd need to do that anyway to make use of works_as_primary). ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
