It 's been months since we went through this whole conversation to revamp
our road classification which haven 't changed to take in account other
possible factors, but to completely draw the line between primary and
secondary class roads in rural areas (which other mappers haven't
completely accepted), I'm presenting again the new definitions by context
as I originally elaborated, except for additions from further observation.:
* Primary
-- Urban: Non-trunk major arterials, usually a numbered national road.
Serves as a major route across town. Just for guidance, usually three-digit
highways under DPWH. Can consider upgrade to trunk if road is like an
expressway between at least two major intersections, with
overpasses/flyovers or underpasses over congested crossings, and most
smaller intersections closed and replaced with a U-turn slot somewhere
nearby.
--Rural/regional: Major non-trunk highways that connect to all other cities
as well as large towns. Lower in importance than trunk, but still the main
way around a region or province. Just for guidance, usually three-digit
highways under DPWH.
* Secondary
--Urban: Minor arterials, connecting at least 3 barangays or districts, not
necessarily within the same city/municipality. Not heavily traveled as the
primary or trunk routes, but still important routes within an urban area.
Can be a "promoted" tertiary (collector) road, with higher quality and more
traffic. Just for guidance, are mostly unnumbered roads under DPWH
("national tertiary roads"), and city/municipal roads.
-- Rural - Smaller highways that connects [a] small town centers[s] or
serves as an alternate route to a major numbered route it parallels. Lower
travel speeds (40-60 kph), and often used by traffic headed to barangays
along it or the town centers it serves. Just for guidance (but can
influence classification), usually a unnumbered national road or provincial
road.
