[talk-au] "Bad" directions on Outback roads

[Michael Collinson]

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".
