What you have on the highway tag (which I may move to a usage page) looks fine to me.<br><br>I couldn't give you an opinion on how to apply them to roads in California because<br>I've never been in that state.<br><br>
I drove a truck for awhile in the US and there are quite a few roads that won't fit nicely<br>into those categories. That's OK. Just make sure that the highway tag represents<br>what the road looks like in general. Later you can add tags for number of lanes,<br>
size of shoulder, shoulder type, divider type, etc.<br><br>I don't know how the rendering rules work exactly. I would like it to use the<br>highway tag if other data is not available.<br><br>I remember a state highway that looked like an Interstate except that it had<br>
turn lanes and stop signs for the traffic on the crossing roads. I think I would<br>tag it as motorway even though it didn't have ramps.<br><br><div class="gmail_quote">On Tue, Apr 22, 2008 at 3:46 AM, Peter Miller <<a href="mailto:peter.miller@itoworld.com">peter.miller@itoworld.com</a>> wrote:<br>

if I have missed something.</span></font></p>

suggest or execute changes where required.</span></font></p>
