@dasmarinas_mapper I already asked the Data Working Group for this user to be blocked and most edits reverted. I managed to review and revert/correct this user's edits, and he's now blackmailing me through diary posts. His presence is a complete headache.

Better clean your mess with the classifications, and please refrain from messing with classifications. Some changes fine, but others questionable. Better focus on other things aside from road classifications, and use good changeset comments that explain what you done. Also, please change username (it's deceptively similar to OpenStreetMap)

Please be more specific with changeset comments. Completely have no idea why you've been here in the first place other than to say "Version Map Paints" in every edit.

Reverted downgrade to trunk, now there is more convincing case for that. Route via Tanauan proposed, but I readily oppose it. Route possibility via Nasugbu would be way too long, so conceding with retaining Dasma-Tagaytay-Lemery-Batangas City trunk

We can settle with that for now. I understand, but I also have objections to Tagaytay-Tanauan becoming trunk, as to leave Santa Rosa-Tagaytay as the only primary in the area. Well, I see now why we should a Dasma-Batangas City link aside from a route via Calamba. I can revert it to how you wanted it.

FYI, if you want further discussion, you may want to register at talk-ph at https://lists.openstreetmap.org/listinfo/talk-ph . I already opened a discussion about it, but since I realized you may be right, I'll be undoing my changes.

Adding to my counterarguments I posted on related changeset that created it, while two parallel trunks can be possible (e.g. Maharlika Highway and Andaya Highway between Tabugon, Santa Elena, Camarines Norte and Sipocot, CamSur, and Maharlika Highway and Route 51 between Santiago and Tuguegarao), it is not convincing unless there is a good deal of primary in between (something that has been already reduced as the Dasma-Batangas via Lemery route got trunk). The pairings of EDSA and Roxas Boulevard, Road 10 and C-4 may appear to be one, but is can be better seen as a ring or belt around a very densely populated area, and serves two different corridors within Metro Manila.

Just a note, I deleted the HA27 relation and remaining references to it since it actually doesn't exist. Also rollbacked the upgrade west of Aguinaldo Highway (discounting jog at Pasong Camachile, Open Canal is too narrow and won't consider it good candidate for primary. Also, road primarily for local traffic.)

Yet, I'll not take on that either because you get multiple jogs and the Dasma-Tanauan being very close to Maharlika Highway and leaving only one primary around and in between: Santa Rosa-Tagaytay or Route 420. By the way, there's even a proposed expressway from Tanauan to Tagaytay, but I'm not convinced. Not even Dasma-Palico-Balayan-Batangas City. Now, can we settle with most numbered routes west of STAR and south of Governor's Drive be primary?

Just why I asked about why you use BrE spelling is because of one guy also from Dasma that got into it and sounded trying hard. I understand now.

I'm about to do this along with the downgrade of Dasma-Tagaytay-Lemery-Batangas City per my multiple counterarguments, but you did it.

Understandable. And yes, Dasma could beat Manila because it's home to PCU and DLSU satellite campus, but you can't deny it's part of the Manila's southern sprawl now. Didn't read my argument against trunk in case Diokno gets closed and you get two detour that you'll might avoid (via Palico and Balayan and via Talisay on the Ligaya Drive "bitukang manok")? I'm already on an edit to downgrade to primary basing on my counterarguments.

(Why use Brit spelling? Trying hard, lol)

The problem is, Lemery and Taal are both medium-sized towns (let's wait years). I'll insist on leaving JP Laurel plus connection to Batangas Pier as the only trunk in Batangas. Tagaytay is a popular getaway, but we don't account that for determining trunk network (trunks link major cities, and Tagaytay isn't among of these as of 2020). Maybe by 5 years, Silang may become city and Tagaytay reaches 100k mark on population, but we should still be careful determining trunks as Cavite pretty dense.

You may treat suburban Cavite as its own conurbation, but it's still part of the sprawl south of Manila, let alone northwest Laguna.

I support that. A primary across the province should be enough, and yes, best route between Olongapo and Dagupan is via Pampanga and Tarlac. That has been one edit I'm considering.

Going back, Route 306 got trunk because it was the main transportation backbone across Zambales, but this is based on a scheme that has the major shortfall of the being more or less obviously Manila-centric; primary being worst offender as you would force such high a class even in a sparsely populated area, with the end result of few to no secondaries around and in between.

To answer why C-4, Road 10 and Roxas Boulevard got trunk is not just to bypass the center of Manila, but also consideration to those who are diligent and use the static map to determine their route (a routing via nav app would lead you through congested city proper and you would like to avoid such route choice). Same also goes with EDSA (in addition to its expressway-like construction, though its much like the metro's larger thoroughfares). The same goes why trunk has been set to Quirino, Diego Cera and Alabang-Zapote in the south (using a nav app with avoid toll option from Magallanes or EDSA-Roxas Boulevard to Alabang, the best route may take you to East Service Road, but except FTI to Nichols, it's narrow and congested and aren't designed for through traffic.)

Back on the Dasma-Batangas City route, I can apply the same reasoning as with the Manila trunk routings, primarily the consideration for those looking up the static map in conjunction with the scenario when Diokno Highway gets closed due to landslide (as like what happened 2016). When Diokno gets closed, an alternative would be via Nasugbu and Balayan, but that would be a longer journey. Another alternative under the Diokno closure scenario is via Talisay and Tanauan, but you might want to avoid steep grade in the Ligaya Drive "bitukang manok", so you might want to travel via Laguna, the path or least resistance.

We can temporarily move the trunk back to via Pagbilao Poblacion as one mapper just updated its eastern leg that is still under construction as of December 2021, but for the rest, they can be reverted as these clearly superseded the older Poblacion routings of Maharlika Highway even though they would involve abrupt turn.

On the bypass of JP Laurel in Lipa, that can get primary at most. Its ultimate purpose is to bypass congested JP Laurel at Marawoy, it looks more like a bypass to those coming from either Balete Road and JP Laurel (and vice versa, whether headed for STAR, Balete, LIMA or Lipa Downtown).

Answering your latest reply, I would still disagree with a Dasma-Batangas trunk via Tagaytay and Lemery with the jog being very obvious at closer zoom. I can discount the comparisons with Maharlika Highway and Andaya across Camarines Norte and CamSur as these are across fairly sparse areas (and both routes are equally important). Denser areas such as CALABARZON and Manila are to be handled differently than most of rural Philippines in terms of road classification.

For Kennon Road or any similar roads, it may matter if it's used by heavy vehicles as trunk should indicate a critical link, but there are factors that support trunk for it:

- It's the shortest and most direct route to Baguio from the south
- It minimizes change of route number
- It is still the critical link to Baguio, considering the ban on trucks and buses there is temporary considering a a plan to rehabilitate it by realigning some segments (tunneling?) and replacing weak bridges.

For the Dasma-Batangas City via Tagaytay and Lemery, it's the main route for those from Dasma, but north of there, the main toll-free route is open for question. And yes, Diokno being landslide-prone also makes its questionable, in addition to involving jogs as one turns to it from Route 436 in the Lemery end or Tagaytay-Nasugbu on the Nasugbu/Calaca end.

I would have to agree with this, Santo Tomas poblacion main roads being largely secondary and isn't much important as the newer Route 4 alignment. Will follow this up with downgrade to Governor Malvar to tertiary

Except Pagbilao bypass, just leave those bypass roads alone.

Understandable (toll-free option on Magic Earth the same), but still far from ideal. Also, this just left one primary between Lipa and Santa Teresita. Trunk via Diokno also not good option because it might get closed due to landslide.

I'll be opposed to retaining Halsema as trunk. Ideally, that forms the shortest route between Baguio and Tuguegarao from the map, but that's not the case of the ground (that goes to Route 110. Also questionable if there's going to be closure due to landslide.

Concurrently, I also oppose keeping the existing primary network as they mostly serve small towns in a largely sparsely populated area. Cordillera already lacks rural secondaries (many of the primaries better fall under that class).
