I suggest that the tags for highway=trunk,primary,secondary,tertiary,unclassified be considered as a function of traffic patterns and not of DOTC designation nor physical appearance or condition.<br><br>These values should also be considered relative to local traffic patterns. This means that levels will be different in an urban and rural setting: a trunk in Metro Manila does not have to be equivalent in function to a trunk in Nueva Vizcaya.<br>
<br>Here are some descriptive interpretations I might suggest (subject to discussion):<br><br>trunk (rural) : long-distance route to traverse across provinces<br>primary (rural) : mid-distance route to travel between towns in a province<br>
secondary (rural) : major streets within rural towns<br>tertiary (rural) : major streets within areas of rural towns<br>unclassified,residential (rural) : other roads in rural towns<br><br>trunk (urban) : long-distance route across the metropolis<br>
primary (urban) : major road within a metropolitan city<br>
secondary (urban) : mid-level road within a metropolitan city<br>
tertiary (urban) : minor road in a metropolitan city<br>
unclassified,residential (urban) : other roads in metropolitan cities<br>
<br><br>I'll admit that I have no fixed idea as to how to tag roads such that relative functional importance within Metro Manila (Cebu, Davao) is consistent when you get outside Metro Manila (Cebu, Davao).<br><br>The problem is that in urban areas, the road density is so high such that we need to differentiate the roads a lot, whereas in rural areas, the density is low.<br>
<br>For Metro Manila, EDSA and *parts* of C-5 are definitely trunk. Commonwealth, Quirino (QC) and McArthur Highway are arguably trunk. Quezon Avenue-Espana, Aurora-Marcos Highway, Ortigas-Ortigas Ext., Quirino (Manila), and Roxas Blvd are not so clear.<br>

<br><tt><font size="2">I'm not objecting but I'm somehow curious about recent<br>
reclassifications of several major roads lately:<br>
<br>
1. Portions of Commonwealth from trunk to primary:<br>
</font></tt><a href="http://www.openstreetmap.org/?lat=14.66209&lon=121.06976&zoom=15&layers=B000FTF" target="_blank"><tt><font size="2">http://www.openstreetmap.org/?lat=14.66209&lon=121.06976&zoom=15&layers=B000FTF</font></tt></a><tt><font size="2"><br>
<br>
2. Mindanao Ave from primary to trunk:<br>
</font></tt><a href="http://www.openstreetmap.org/?lat=14.67085&lon=121.03234&zoom=15&layers=B000FTF" target="_blank"><tt><font size="2">http://www.openstreetmap.org/?lat=14.67085&lon=121.03234&zoom=15&layers=B000FTF</font></tt></a><tt><font size="2"><br>
<br>
3. Some parts of Quirino are either primary or trunk:<br>
</font></tt><a href="http://www.openstreetmap.org/?lat=14.69974&lon=121.03273&zoom=15&layers=B000FTF" target="_blank"><tt><font size="2">http://www.openstreetmap.org/?lat=14.69974&lon=121.03273&zoom=15&layers=B000FTF</font></tt></a><tt><font size="2"><br>
<br>
4. MacArthur Hiway from primary to trunk:<br>
</font></tt><a href="http://www.openstreetmap.org/?lat=14.6755&lon=120.982&zoom=15&layers=B000FTF" target="_blank"><tt><font size="2">http://www.openstreetmap.org/?lat=14.6755&lon=120.982&zoom=15&layers=B000FTF</font></tt></a><tt><font size="2"><br>
<br>
If we follow this trend, then I think Roxas Blvd should also be trunk as
well:<br>
</font></tt><a href="http://www.openstreetmap.org/?lat=14.53551&lon=121.00028&zoom=15&layers=B000FTF" target="_blank"><tt><font size="2">http://www.openstreetmap.org/?lat=14.53551&lon=121.00028&zoom=15&layers=B000FTF</font></tt></a><tt><font size="2"><br>
<br>
Which means Metro Manila roads will be a whole lot greener (in the map<br>
at least).<br>
<br>
