Lesson 1: PNRN Flashcards
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
The first
comprehensive reference to a Road Classification System in
the Philippines.
Executive Order (E.O.) No. 483, s. 1951
The Philippine Highway Act of
1953, which revised the road classification system to include
military highway needs.
R.A. No. 917
The order that
provides the current classification system and criteria for
each road classification.
Department Order NO. 133 s. 2018
Contiguous roads connecting
major cities and forming the backbone of the national road
system.
National Primary Roads
Roads directly connecting
major ports, airports, tourist centers, and cities to national
primary roads.
National Secondary Roads
Other existing roads under DPWH which perform local function
National Tertiary Roads
