About a week since I presented the first version of the proposed road classifications and their correspondences, I looked back on the DPWH documents that defines the road classifications for the Philippines, and the previous road classes are rather like this:
*Expressway *National primary road **North-South Backbone **East-West Laterals **Other Roads of Strategic Importance *National secondary road *National tertiary road *Provincial road *City/municipal road *Barangay road Actually, the new classifications are fundamentally the same, except that the subcategories of national primary roads have been reduced to two, based on number allocation: *Main routes (N1-N49) *Other primary routes (N50-99) Given that, I see that the present classification we have been using really works fine, except that we need to better describe some classifications, for these reasons: * The primary category needs to be better defined, as it seems to have been overused, and we should restrict this to some primary national roads, and all secondary routes (perhaps except for N120, as part of AH26). We have discussions back in 2009 to restrict the primary classification to national roads, but it seems to have stalled. * We might need to cut down the routes tagged as trunk, and I am considering to have it used only on the primary routes (1-2) digits, with a handful of exceptions >From those points I made, I get into this modified proposal: Rural: *Motorway - expressways *Trunk - major primary national roads (1-2 digit routes), that connect major cities and of strategic importance. *Primary - less important national roads, secondary national roads (3-digit routes) *Secondary - provincial roads, and minor arterial roads in municipalities *Tertiary - other roads that connect barangays with each other and the secondary network *Unclassified - other non-residential rural roads, such as those serving as the only connection to an isolated sitio/purok or barangay *Residential - residential streets Urban: *Motorway - expressways *Trunk - major through route through a city or metropolitan area, usually a primary national road (e.g. EDSA), all of Route 120 (as western alternate alignment of AH26 through Metro Manila) *Primary - other major urban routes, usually a secondary national road. *Secondary - minor urban arteries, connects 3 or more barangays or districts, and not a numbered national road *Tertiary - **collector roads inside barangays or districts, usually narrow and with traffic calming features (meandering alignments, humps, low speeds) **other roads connecting barangays and districts with each other and the secondary network. Usually non-contiguous, and has the same characteristics as mentioned above. *Unclassified - non-residential street that does not fit the tertiary classification. *Residential - residential streets wide enough for cars In addition, we should remove the living street classification, as Philippine traffic law has no equivalent to it, and better retag those according to the mapper's judgment. We haven't began any discussions about this since I presented the first proposal, so we need to get through this.
