You could do this with a separate kml or xml dataset. The question already raised by others here is the benefit for OSM if the route is only used by one consumer, is not visible on the ground, is not permanent and not verifiable...

I also agree that the route data is not of primary (or secondary ;-) ) interest to osm. Instead you could add an attribute to the roads whether there is winter service or not. This is already done somewhere, e.g. with the tag gritting http://taginfo.openstreetmap.org/search?q=gritting and with the tag winter_service cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
Re: [Tagging] Gritting routes
Craig said: What is the point in mapping roads where the gritter drives, if it is not gritting there? How is that useful for anyone? In the UK any government data based on a map tends to be derived from the national mapping agency and as such creates licence issues. We therefore opt to use the gritting route schedules. These are literally a list of instructions in the form: * Leave depot, turn Right * GRIT to end of road, turn left * TRAVEL to main street, turn left * GRIT to ... and so on...

Regards, Rob p.s. For some context, whether a road is gritted or not is quite important in the UK as we are lazy and don't tend to bother with winter tyres/chains etc.. There is a fine balance between gritting more so that the roads are kept moving (economic and safety benefit) and gritting less to reduce direct costs and the corrosion/environmental cost of excess salt/grit. ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

It is useful for drivers to know whether or not a road will be gritted, but it doesn't matter what order the roads are gritted, or where the truck goes before or after. I suspect most of these routes are not really fixed, different drivers could cover the roads in a different order if they wanted to. Comparing it to bus routes, you only map where the bus is actually carrying or picking up passengers, not where it is driving empty to and from the depot. ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
[Tagging] Gritting routes
Hi All, I have some winter gritting/salting routes that I am trying to work out how best to tag them. I was thinking of creating a route relation, but I may need to add some new roles: * forward:grit implies the gritting truck grits this road whilst travelling in the direction of the way. * forward:travel implies the gritting truck drives along the direction of the way but does NOT grit it. Is this ok? I also have a concern that JOSM warns me if I try to add the same road way to the route twice. For gritting routes this is necessary - for example, grit Road A to roundabout, u-turn and travel back on Road A (but do not grit). In this example Road A would have to be added to the relation twice first as forward:grit and then as backward:travel. Is it okay if I ignore JOSMs error in this case?

Re: [Tagging] Gritting routes
Hi Rob, it's only a warning of josm. Read it as: Hey, you made something which may be an error. Are you sure it's what you wanted to do? and if you answer this question with yes, ignore it On the other hand: What's the benefit of having gritting routes in osm? are they stable? Are they followed like bus routes, or changed according to weather conditions and other parameters? It may be my experience in mid-western Germany, away from any bigger mountain, but here at most there are severity levels for particular streets (which are first rank gritted, which are unimportant and so on). If it's unstable or changing from year to year I would suggest not to tag them at all. regards Peter Am 23.03.2014 23:07, schrieb Rob Nickerson: Hi All, I have some winter gritting/salting routes that I am trying to work out how best to tag them.

[Tagging] Gritting routes
Thanks, Happy to ignore JOSMs error, but don't want to have someone else change my route relation if it flags as a QA bug (hence posting here to gather people's thoughts ideas). They're as stable as bus routes in my area as the local authority has to ensure the correct roads are gritted and the best way to do this is to have prearranged routes.
