Classification

The current road classification for the Philippines has been since WikiProject Philippines started, but has not been applied correctly in parts of the country. With the implementation of a national road numbering system from 2014 (with signing started on 2015 in AH26 sections), a better classification system, with the official designation taken in regard, not just purpose, has been needed, as an amendment to the current system, which has been improperly implemented in various places. Proportionality and consistency must be also considered.

Most of this road classification guidelines are based on the Canadian tagging guidelines for roads, but with slight modifications to fit the Philippine context. Guidelines in Highway Tag Africa are also applied, especially when tagging road networks in the poorest provinces.

The full inventory of national roads and their routes can be found at the DPWH 2017 Road Data page, which is divided by region (excluding ARMM) and district office. Also, that can help find missing numbered routes where they are currently not mapped, but the best practice is to find the numbers on the ground.

Expressways

Motorway

In the Philippines, highway=motorway correspond to expressways, controlled-access highways that are multi-lane divided roads, mostly tolled. North Luzon Expressway, South Luzon Expressway, STAR Tollway, etc., fall under that classification. They are numbered in the format E[number], yet, the numbering has been only implemented in sections where AH26 runs.

A few expressway segments, such as STAR Tollway between Lipa and Batangas City exits and North Luzon Expressway between Clark Spur Road and Santa Ines exits, are originally two-lane undivided roads, and are tagged also as highway=motorway, with the addition of oneway=no, so to contradict the implied one-way tag. As of 2016, only the majority of the Subic-Tipo Expressway are mapped as a single line with oneway=no.

National roads

Trunk

A highway=trunk is any nationally-important road that are not expressway-grade. In the Philippines, they include most primary national roads, as well as secondary national roads that have the highest importance over others in the system. These highways connect the major cities (with populations above 100,000), as well as provincial capitals, other regional centers and major seaports (especially, RoRo ports). In some areas, they can have partial grade separation, but they do not need to be divided and controlled-access. Highways in the Autonomous Region in Muslim Mindanao that connect the gaps in Routes 1 and 75 also fall in this classification.

In Luzon, trunk class falls on the routes listed below. Notes, and known road names are placed in parentheses:

  • N1 (Maharlika Highway, Cagayan Valley Road, EDSA, Manila South Road)

Primary

A highway=primary is a major highway that connects major municipalities with the backbone highway system, and function as a primary artery in the area. In rural areas, they are two-lane roads with a marked center line (with a few having no lines), while in urban areas, they can be multi-lane roads. They do not need to pass over the town center or downtown district (poblacion).

Other than those that are highway=trunk, or lower, by overall importance, secondary national roads (3-digit routes) are usually highway=primary. Tertiary national roads that function as a principal artery are also under this class.

Local government-maintained roads

Secondary

A secondary road is a non-major route that serves as a link in the national system, and typically follows shorter routes. They mostly have two lanes, but in urban areas they may be multi-lane and/or dual carriageway. Other than the majority of DPWH-maintained tertiary national roads that follows the definition of this designation, most roads of this class do not have lane markings. In some provinces, quality of this roads may be even worse.

Recommendation:

  • Secondary, tertiary - All roads that function as links to minor municipalities, or principal access to barangays. Tertiary national roads that spur away from the main network and function as links to minor municipalities or principal access to barangays, city and municipal arterial roads, and provincial roads.

Major arterials in private developments (including subdivisions) that are public access or permissive access also falls under secondary.

Tertiary

Tertiary roads are roads that are less important than secondary roads but more important than unclassified roads. Most of this roads are the major road between and within barangays, and are usually maintained by the barangay government. They mostly lack road markings, and have worse quality, especially in the poorest provinces.

This class differs in characteristics in the urban and rural areas, so does the recommendation:

  • Urban
    • Narrow: usually not wider than two to four lanes
    • Local access: typically used for access to residential and commercial areas, and is divided by major highways.
  • Traffic calming: low speed limit, frequent uncontrolled intersections, humps, curves, shared traffic with pedestrians
  • Rural
    • Typically a local access road used to serve sparsely populated barangay[s] and branches from a higher importance road. These may be paved, but may be unpaved in the underdeveloped provinces. They are usually narrow and has shared motor, foot, and animal traffic.

Main access roads in restricted-access subdivisions are previously recommended to be classified as tertiary, but they must downgraded to unclassified, with addition of necessary access tags.

Unclassified

This includes all non-major rural roads that link smaller areas, including, but not limited to non-major barangay roads and the vast majority of farm-to-market roads. Maintenance varies from well-paved to unsealed.

Recommendations:

  • Rural:
    • More narrow barangay roads, usually spurring from a more frequently used route. Typically used only to access a sitio/purok from the major roads, and narrow (usually one lane).
    • Most farm-to-market roads, linking farmlands with a major road
  • Urban: Non-major roads in barangays that serve as a street over a commercial district or a distributor road in a barangay. Can be distinguishable by having a narrow right of way.
