We have a reasonable if not perfect tagging system for a router to
assess (and make assumptions) about the quality of a road for various
types of vehicle in BEST CASE conditions. motorway versus track,
tracktype, asphalt versus gravel being the main ones.
From a router point of view it would be nice to dynamically place
routing penalties on roads or stretches of road according to
temperature, snow, rain, side wind (and ?). Simplistically, input "snow"
and pick up from OSM tags advising "often impassable in snow" or "snow
chains advised in winter" and then the router can decide how much
penalty to apply given projected conditions and vehicle type.
Sounds reasonably simple to devise and implement. I've played mentally
with the same idea for suggesting footpath routes that vary depending on
the weather.
More esoterically and more real time would be a community project to
develop an open overlay database of transient data where the public
and/or authorities can label osm ways with advisories quantitative
enough for routers to again assess a routing penalty. The obvious
starting point would be a simply "closed".

So what's the best way to avoid the same issues?
Thanks
