</div>On relations, i think we have a clear, agreed upon standard that<br>
the network tag indicates the grouping of highways to which a particular<br>
route belongs, and the ref tag indicates the identifier within that group.<br>
<br>
so you end up with something like<br>
<br>
network=US:AZ:Loop<br>
ref=101<br>
<br>
although some might prefer<br>
<br>
network=US:AZ<br>
ref=Loop 101<br>
<br>
either one contains enough information in an easily parsed format to allow<br>
data consumers to accomplish what they need to do. i lean towards the former<br>
tagging approach </blockquote><div><br></div><div>I went and verified some things about bannered routes. It looks like the current shield rendering looks for network=X:Y:Modifier. So for example the US 50 truck route in Cincinnati is network=US:US:Truck and ref=50. The relation and rendering can be seen at the following two URLs:</div>

<div><br></div><div>Looking around it looks like the other convention that has some decent use in the database (but is not currently supported by any renderings) is to add a modifier=Truck/Business/Spur/etc tag. You can see current usage in taginfo:</div>
