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

[Ben Robbins]

>Is this new?

No not really, I breifly mentioned it before buy got side tracked with a 
fasinating debate about gates!.

>If you're talking about tracks
>highway="motorway" etcetc...

I'm talking about all the roads that are just unclassified.  Lanes=0.5 
doesnt seem logical.  I'm specifically talking about the 4 variations of 
unclassified roads that can be found relative to the width of the average 
veicle.  1) ones that are 2 and a bit viecles wide, 2) the ones that are 2 
viecles wide just 3) the ones that are less than 2, and 4) the ones that are 
less than 2, with enbanked sides/walls/ditches etc.

>Why 1/2/3/4 ?

Casue I'm awaiting a better suggestion, for some standard types

>use_passing_areas

These would be additonal

If people can think of a more interesting, but still simple way of tagging 
them that will be good.  I was just saying, if nothing comes of this I shall 
just tag 1/2/3/4.

All I request is that it can be used additional to the highway tag.  So 
highway=unclassified, highwaytype=type1/2/3/4 is an example.

>I can not think of a group of public roads

>suggesting

I'm suggestion the abilty to clearly split up the types of highways wich are 
very different, but politically are the same.  For private property I tag as 
tracktypes, rather than highway, but thats a different, and somewhat nasty 
debate.   I just wish to lable the roadwidth, but have some standard types, 
although people could just stick x meters/feet if they want.

Basically, I wish to be able to look at a countryside area and not just see 
unclassified roads everywhere, as In following it I may find myself stuck 
behind a horse with no room to pass, and then having to reverse so a lorry 
can get past; this all making my average speed abotu 5mph, while it would 
have been about 50mph if I had gone on the other unclassified road, wich on 
the osm map is currently mapped identically.   This happened today, after 
posting the first post.

The use of the tag I'm requesting would be similar to how lanes="2" is used. 
  It would be additional to the highway=motoway tag.

>How about a sign with a questionmark on it

Yep, thats a good idea.

I was thinking more along the lines of having a symbol that isnt a node that 
is only visible on render, and involves selecting and checking nodes, but 
instead is a completly seperate bit of data from segments/nodes and ways, 
and is just a symbol that can be used, and seen instantly.

One idea (I think its Etiennes) was to have a border around the area youve 
mapped, so you can progressivly push it backwards.  The problem with that is 
if more than one person maps an area, wich is definatly going to happen at 
some point.  Just placing 'unexploered territory' signs would be like 
marking a stub on wikipedia, and be helpful to all.

>You are talking about right of way at an interchange, aren't you?  I
>think that.....

I won't pretend to know anything on the topic of routeplanners, I'm just 
concerned, and hope that it has been considered and there is some suggested 
way.  When the giveway/prioty roads switch I suppose it would need to be 
tagged as being a cross roads where all enterences give way.

Sorry if my post isn't very clear.  If it's still unclear I'll revert to 
using images, cuase I find it a lot easier to discribe stuff with pictures.

Thanks

Ben
