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

[Jherome Miguel]

Hi all,

After somewhat slow progress to gather ideas and feedback for a new road
classification scheme, I finally decided to write the final version of the
new tagging scheme at:
https://wiki.openstreetmap.org/wiki/Philippines/Mapping_conventions/Roads
(see “Classification” section)

The proposal is planned to replace those at
https://wiki.openstreetmap.org/wiki/Philippines/Mapping_conventions (sections,
“Roads”, “Names”)

*Why? *The existing road classification scheme since 2015 needs a major
rewrite since I’m seeing major problems with the tree analogy used to
justify the existing scheme. Why use primary for every road to each
municipality regardless of its population size (just because they’re a
branch or an alternate to a trunk)? Shouldn’t we use trunks only on the
most important highway links between the largest cities beside the
expressways? Many of our provinces lack secondaries in the rural area but
do have lots of tertiaries surrounded by trunk and primary roads (and a
total lack of secondary roads). Lots of Philippines mappers (including me)
ignore that bad scheme, which just came to effect without discussion or
consultation. It’s also time for us to take community population sizes as
well as designations in account when classifying roads.

Also, guidelines about road names are to be affected as well (following
latest discussion). This includes changes in the existing guideline to
prefer full names as used in addresses (since names posted in street signs
can be inconsistent). One open question is on how to name many of the major
rural roads without posted names (national roads aside, whose names, unless
the locally verifiable posted name is different, can be found from the DPWH
road database) until their actual names are verified. For me, it’s in the
form “<most important community>-<less important community> Road”, though I
also experimented with adding noname=yes instead of adding placeholder
names using the format mentioned above.

Any comments/suggestion/feedback on this are welcome here or on the
article’s talk page.

Thanks,
