there is a major disconnect between what people think is "right" and
what the wiki calls for. from<br>
<br></div></blockquote></div><div>Agreed. One of the reasons I started this discussion was to make sure that what the wiki calls for is still "right". As far as rendering the shields go, I think we should stick with the established tagging scheme and let whoever writes the parser worry about stripping the network=US: out of US:* .<br>

we see:<br>

network=US:I, US:I:BUSINESS, US:I:DOWNTOWN, US:I:FUTURE Required.
Business, downtown and future routes have their own signage <br>
<br>
and<br>
<br>
ref=* Required. ex. 90 <br>

and many people have been busy building relations to fit this
specification.<br>

</blockquote></div></div>Moving back to one of my original questions, I think Nakor was the only one to respond to the 2 relations per state (1 relation each way) vs 1 relation with rolls per state question.<br><br>The Diff code is a little tangled, but from the WIKI, it looks like only interstates I-24, I-26, I-84 were merged from 2-relations into 1-relation with roles. The rest of the system still has the relation numbers listed in the WIKI. From what I can see, it looks like there's no clear winner between the two systems, although quite a few Interstates are still missing supers.<br>
<br>I'm happy to use either method, but one of the reasons why I prefer the 1-relation-per-direction method is that it lets me quickly find areas that need to be split into dual carriageways.<br><font color="#888888"><br>
