|To define if there is snow removal, gritting or salting on highways during winter time.|
|Used on these elements|
|Tools for this tag|
The winter service tag is used to specify, if the highway is serviced during winter to remain in working condition. Winter service of roads may contain snow plowing, salting, gritting etc.
Note that recent snowfall without snowplowing/gritting is not evidence of lack of winter maintenance - road may be simply of a lower priority.
|winter_service=no||No winter servicing at all. The highway might not be usable in wintertime with normal vehicles.|
|winter_service=limited||Some winter service, but only occasionally. In Germany there are usually matching traffic signs.|
|winter_service=yes||The road is serviced in winter. This does not guarantee the usability of the road in extreme weather.|
Applies to ways and areas (e.g. pedestrian areas or parking lots). A single default value is not defined, because conventions vary depending on the area.
If known one can also tag more detailed similar to Mappa_Mercia.
The main tag only describes the general level of winter service. In addition you can use more specific subkeys that describe other features:
- maintenance=gritting - tag with some use
- winter_service:gritting=* or winter_service:salting=* [Note: as of Dec 2020 neither of these tags has been used]
Use by data consumers
When routing, roads should usually be presumed to be usable also in winter if the key is missing. Service status will be defined for all suitable ways to reflect which ways have an unknown status.
- snowplowing=* - Specifies whether or not a way is regularly snowplowed.
- maintenance=gritting + gritting=* - An equivalent tag introduced over 10 years ago in the UK with usage mostly in England. The tag has been used for public service maps of planned winter maintenance across the West Midlands. (In the UK gritting is the primary type of winter service).
- winter_road=* - Seasonal roads in northern regions that are functioning during winter, usually impassable in summer.
- ice_road=* - Seasonal roads in cold regions that are laid upon frozen water basins and rivers.
