[talk-ph] Proposed mapping guidelines for roads (classifications, construction, names)

Hello everyone,

The additional considerations seem well-thought-out to me.

I've also went ahead and documented the designation values that were 
proposed by Seav back in 2018. Are there any opinions on this?

There are a few more important points that have been raised or at least 
vaguely mentioned before but have never really been discussed.
____

How should we classify roads on smaller islands that do not have any 
single municipality or city that would meet the proposed population 
criteria for primary roads? Currently there does not seem to be a 
uniform approach. As specific examples we could look at the following 
islands:
Samal, population 105k, area 300 km2, currently secondary
Ticao, population 90k, area 330 km2, currently secondary
Burias, population 90k, area 420 km2, currently primary
Sibuyan, population 40k, area 450 km2, currently primary
Alabat, population 40k, area 200 km2, currently tertiary

Should we just consider total island population? This would lead to 
upgrade to primary in Samal, upgrade on Alabat to secondary and 
downgrade to secondary on Burias and Sibuyan. Or should we not apply 
population criteria here considering that for example Sibuyan 
Circumferential road has a lenght of almost 100km? Personally I would 
tend to option 2 as a limitation to only secondary/tertiary/unclassified 
might be insufficient in distinguishing relative importance of 
individual roads on such large islands.

Also, the main roads on three of these islands have been recently 
downgraded by apple data team. In two cases (Samal and Alabat) new 
classification does neither reflect old classification conventions nor 
the ongoing proposal. While downgrade in case of Ticao seems arbitrary 
given the almost identical population/area/road length as Burias. Would 
anyone support reaching out to ADT about this?
____

Another aspect of classifications that I think we should specify are 
roads under construction. Especially in cases of multi-year road opening 
projects where roads already serve as footway, cycleway, residential, 
unclassified or tertiary long before full connectivity is achieved. 
Maybe we could start building a consensus on this by analyzing specific 
situations:

Example 1: Cauayan City Bypass Road 
(https://www.openstreetmap.org/way/844417527)
Whole length is accesible by foot and bike, except 3 interruptions by 
unfinished waterway crossings, one part of the alignment is an existing 
section of unclassified road. Should we tag all sections that are in 
partial use already with highway=primary with current access 
restrictions/surface/width and only leave the unpassable sections as 
highway=construction? Or should every section be tagged by it's current 
usage?

Example 2: Northern Section of Mindoro Circumferential Road 
(https://www.openstreetmap.org/way/776641003)
Whole length is frequently traversed by cyclists and most likely also 
motorbikes. Same question, should everything be tagged as 
highway=primary with access restrictions/surface/width or should 
unfinished sections be changed to unclassified and path? What about the 
already finished sections in between Abra de Ilog Port and Puerto 
Galera? Should they be downgraded to tertiary until connectivity is 
achieved?

I propose to use method 1 in case of major bypass roads in or near urban 
areas (example 1) given that these usually really are perceived as 
unfinished highways. On the other side I propose to use method 2 for 
construction projects in rural areas (example 2) considering that almost 
always these routes are replacing segments of pre-existing local roads 
or trails and the local perceptions is that there is no highway yet.
____

One last point regarding road naming, it would be good if we could agree 
on an uniform approach about whether we should use spaces before and 
after hyphens. This might seem like a trivial question, but I think the 
current situation is a bit chaotic, especially for long routes where 
variants might alternate multiple times along the course. Sometimes 
there's even a third variant with em dashes (—).
Example: Davao-Surigao Coastal Road vs. Davao - Surigao Coastal Road 
(https://www.openstreetmap.org/way/894848575)
I'd like to propose that we stick to regular hyphens without spaces to 
conform with the orthography in official records and documents.
