<div id="gmail-m_-3646339629974272645v1_rc_sig"></div><p>My understanding that there are several distinct “highway” concepts in Australia. When you are referring to <b>state routes </b>and <b>national routes</b>, are you talking about the old, numberic route numbering system? Or, are you talking about highways that have been gazetted as a "state controlled highway", such as <a>State (Bell/Springvale) Highway</a>. Does it actually make sense to have the "A1" as part of the "National Highway" network, given that it is an alphanumeric route?</p>
<p>I don't believe it is possible to assume that every numbered route has a specific name, and vice versa (The A1!=Princes Highway!=Imlay Street, Eden), but it would be help to update the network tags to be more in line with international practice.</p></div></blockquote><div>Scarily enough, I've just been looking at these maps over the last couple of days! <br></div><div><br></div><div><a href="https://www.tmr.qld.gov.au/Travel-and-transport/Maps-and-guides/Queensland-State-controlled-roads-and-region-maps">https://www.tmr.qld.gov.au/Travel-and-transport/Maps-and-guides/Queensland-State-controlled-roads-and-region-maps</a></div><div><br></div><div>Unfortunately, though, although very pretty, they don't really say much to a layman (& we would need permission to use the info anyway), eg <br></div><div><a href="https://www.tmr.qld.gov.au/-/media/Travelandtransport/Maps-and-guides/regiondistrictmaps/centralqldregion.pdf?la=en">https://www.tmr.qld.gov.au/-/media/Travelandtransport/Maps-and-guides/regiondistrictmaps/centralqldregion.pdf?la=en</a> has lots of pretty coloured lines on it that depict 9 different types of road network!, but I don't think any of them are actually signposted the same as they show here? <br></div><div><br></div><div>I know that looking at the GC map, the M1 is marked as 12A & called Pacific Hwy, while the Gold Coast Hwy is 11B but it's signposted as State Route 2?</div><div><br></div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr">Thanks<div><br></div><div>Graeme</div></div></div></div></div></div></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="font-size:10pt;font-family:Verdana,Geneva,sans-serif">

<div dir="ltr">Hi Andrew,
<div> </div>
<div>No I had not seen that and it's really helpful thank you.</div>
<div> </div>
<div>This is quite challenging to explain in an email but I will try...</div>
<div> </div>
<div><b>Scenario:</b> Given a way, how can I determine if that way is part of a state or national route with a name?</div>
<div> </div>
<div><b>Scenario in Action:</b></div>
<div>
<ul>
<li>Given the way "Mulgrave Street Gin Gin QLD" <a href="https://www.openstreetmap.org/way/31973923" rel="noopener noreferrer" target="_blank">https://www.openstreetmap.org/way/31973923</a></li>
<li>Is this part of any relation.... Yes there are 2
<ul>
<li>First relation is the A1, is this a national/state Highway YES! because it has the route=road, network=NH <a href="https://www.openstreetmap.org/relation/198279" rel="noopener noreferrer" target="_blank">https://www.openstreetmap.org/relation/198279</a></li>
<li>Second relation is "Bruce Highway", is this national/state, NO! because it does not have a network=NH or S tag. <a href="https://www.openstreetmap.org/relation/198331" rel="noopener noreferrer" target="_blank">https://www.openstreetmap.org/relation/198331</a></li>
</ul>
</li>
</ul>
<div><b>What's missing from the above:</b></div>
<ul>
<li>The Bruce Highway relation <a href="https://www.openstreetmap.org/relation/198331" rel="noopener noreferrer" target="_blank">https://www.openstreetmap.org/relation/198331</a>
<ul>
<li>Does not identify that it is related to the A1 - National Highway</li>
<li>Does not identify that south most section in North Brisbane the M1</li>
<li>Does not identity that this is a State Route - <b><u>but I am unsure if it should</u></b></li>
</ul>
</li>
<li>Similarly, the A1 relation <a href="https://www.openstreetmap.org/relation/198279" rel="noopener noreferrer" target="_blank">https://www.openstreetmap.org/relation/198279</a>
<ul>
<li>Does not identify that it is related to the Bruce Highway (route)</li>
</ul>
</li>
<li>The way "Mulgrave Street Gin Gin QLD" <a href="https://www.openstreetmap.org/way/31973923" rel="noopener noreferrer" target="_blank">https://www.openstreetmap.org/way/31973923</a>
<ul>
<li>Can't be reliably determined to be part of a state/national route and found to be named "Bruce Highway". Yes, I can say its on the A1 (national highway) but I can't say that the Bruce Highway is a State/Road route</li>
</ul>
</li>
</ul>
<div> </div>
</div>
<div><b>My 2c</b></div>
<div> </div>
<div>I'm unsure if what I am looking for should exist in a hierarchy of parent/child relations, or if it is best left to trawling through tags and finding references by convention and hope that things are tagged correctly. I kinda think the first is correct, or else why would OSM even have relations?</div>
<div> </div>
<div>Parent Child relation down to the way members....</div>
<div>
<ul>
<li>RELATION: name=National Highway; ref=A1; route=road; network=NH
<ul>
<li>RELATION: name=Bruce Highway ref=A1:M3; route=road; network=S <--- not sure if this is S or NH
<ul>
<li>RELATION: name=Bruce Highway ref=A1; route=road; network=S
<ul>
<li>WAY....</li>
<li>WAY....</li>
</ul>
</li>
<li>RELATION: name=Bruce Highway ref=M1; route=road; network=S
<ul>
<li>WAY...</li>
<li>WAY...</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
<div> </div>
</div>
<div>The above would allow a way's membership and hierarchy to be traversed.</div>
<div> </div>
