[OSM-talk] Road Widths, Stubs and Priority/Giveway

Tim,

This sounds like your talking about the phisical properties of the surface 
of the road, rather than road widths.  I agree its inportant to tag this and 
have debated this a LOT before.  I have given up now, but the splitting up 
of the types of track's is still on the proposed features page.

>(grass -> mud -> dirt -> gravel -> roughly surfaced

Yep, I've covered it with tracktypes...I don't mean to resererect old 
battles, but yeah.

>For example I don't care whether a track is gravel or dirt or grass etc

Fair enough, but others may

>lanes=2 passing easy
>lanes=1.5 passing tricky
>lanes=1 passing is a real pain

I see where your comming from but there is a slight problem.  It would 
really be about.

lanes=2 (passing easy)
lanes=2 (passing cautious)
lanes=1.5 or less (passing inposible, so use grass <or whatever> on either 
side)
lanes=1.5 or less (passing inposible on grass on either side <or whatever>)

The top one could maybe just be lanes=2.5, as its wider, but the information 
the tag then gives sounds wrong, becuase there is only 2 lanes, but they are 
reletively wide.  Also on the other 3 they lack lanes, so again the tag 
doesnt seem too fitting.

Yep, agreed.  Ususally, OS get the tracks completly wrong, as they have 
changed too much for them to keep up with.   They still try to state the 
difference.  Its also inportant to note they are solid grey lines, rather 
than colours, wich is because they are not public unless otherwise marked.  
Colours are used to indicate public access.   Thats my view, I don't wish to 
start a battle about that.
