The system that organizes and regulates the various categories of roads to contribute to the efficient management and development of the national road network.
Road classification
Roads designated with distinct route numbers, specifically allocated for “main” routes or corridors that establish connections among three or more cities.
National Primary roads
Roads that link two cities and
complement the national arterial roads by facilitating access to additional major population and production centers.
National Secondary Roads
A distinct classification of roads serving as local roads within the national road network, primarily managed by local government units (LGUs), with no route numbers assigned.
National Tertiary roads
A system introduced to simplify and rationalize navigation along national roads classified as Primary or Secondary, ensuring roads of a certain classification and numbering scheme meet similar performance standards.
Route Numbering System (RNS)
Relates to funding or ownership of the road, determining which organization is responsible for managing and maintaining an individual road
Road Conversion
An index displaying road condition values along with corresponding condition ratings and recommended treatment measures.
Visual Condition Index (VCI)
A standardized measure used to quantify the roughness or irregularities in the pavement surface that adversely affect the riding quality of a vehicle.
International Roughness Index (IRI)
A measure that quantifies the road network’s extent within a given area, usually per unit of land area, providing valuable information about accessibility and connectivity crucial for economic development, transportation planning, and infrastructure management.
Road Density
A group established to recommend changes to the road classification system.
Technical Working Group (TWG)
A system established to improve planning and management of the national road network.
