roads continuous in extent that form part of the main trunk line system; all roads leading to national ports, national seaports, parks or coast-to-coast roads.

National road

roads connecting one municipality with another; all roads extending from a municipality or from a provincial or national roads to a public wharf or railway station; and any other road to be designated as such by the Sangguniang Panlalalwigan.

Provincial road

these roads / streets within the urban area of the city to be designated as such by the Sangguniang Panglungsod.

City road

these roads / streets within the poblacion area of a municipality to be designated as such by the Sangguniang Bayan.

Municipal road

defined as a hierarchy in terms of road types and according to the major functions the roads will serve. The main classification is whether the road is to be used primarily for movement or for access.

Road network

A road corridor connecting several highly-urbanized centers with ribbon-type of development of commercial, business and industrial establishment.

Expressway

rural roads located either outside the urban area of city or outside industrial, commercial or residential subdivisions which act as feeder farm-to-market roads, and which are not otherwise classified as national, provincial, city or municipal roads.

1,2,3&4 ONLY

On open country roads with no “blind corners” not closely bordered by habitation, What is the maximum speed of passenger cars and motorcycles?

80kph

On open country roads with no “blind corners” not closely bordered by habitation, What is the maximun speed of motor trucks and buses?

50kph

On “through streets” or boulevards clear of traffic, with no “blind corners”, The maximum speeds of passenger cars and motorcycles is?

40kph

On “through streets” or boulevards clear of traffic, with no “blind corners”, The maximum speeds of motor trucks and buses is?

30kph

On city and municipal streets, with light traffic, when not designated “throughstreets” what os the maximum speeds of passenger cars, motorcycles, motor trucks and buses ?

30kph

Through crowded streets, approaching intersections at “blind corners”, passing school zones, passing other vehicles which are stationary, or for similar dangerous circumstances what is the maximun speeds of passenger cars, motorcycles, motor trucks and buses?

20kph

Max speeds on High Risk Pedestrian Areas

40kph

Max speeds on Low Risk Pedestrian Areas

60kph

An ____ speed limit would be appropriate on a high standard duplicated carriageway road where there is only occasional access from adjoining properties.

80kph

A _____ speed limit would only be appropriate on very high standard expressways, which have a low crash rate. These expressways should have a high standard geometry and should be free of roadside hazards. If hazards exist and they cannot be removed or modified, they should be shielded with a safety barrier.

100kph

the maximum number of vehicles, which have a reasonable expectation of passing over a given section of a lane or a roadway in one direction or in both directions during one hour under prevailing road and traffic conditions.

Road capacity

Ideal capacity of a road is

2,000 vehicles/hour (vph).

Vulnerable road users include: 1. Pedestrians 2. People with disabilities 3. Non-motorized vehicles 4. Motorcycles

All of the above

An even, well drained and good textured road surface can maximize safety on the road and prevent traffic accidents occurring

Road Surface

The areas where the state of the road surface condition and good texture of the road surface is particularly important are where vehicles are required to brake or maneuver suddenly such as: 1. On the approach to traffic signals 2. At roundabouts 3. Around tight curves 4. Highway 5. On downhill slopes.

1,2,3 & 5 ONLY

is the longitudinal profile along the centerline of the road. It is made up of a series of grades and vertical curves. The profile is determined by a consideration of the planning, access, topographic, geological, design controls, earthworks and other economic aspects.

Vertical alignment

The basic lane width appropriate for national roads is _____. (can be reduced on the basis of economy)

3.35m

For a single lane road traffic the lane width is

4.0 m

For a two lane national road the minimum width is

2 x 3.35 m lanes (total 6.7 m).

The design of overtaking lanes and climbing lanes requires the consideration of the: 1. Initial diverge taper; 2. Auxiliary lane length; 3. End or merge taper.

All of the Above

is required at the start of an auxiliary lane to provide for the lateral movement of traffic.

Taper

is the dividing of a single stream of traffic into separate streams. The diverge taper length for a through traffic lane is based on a lateral shift movement of traffic of 1 m/s.

Diverge taper

of 1 m/s means that for every second of travel in the longitudinal direction, there is a transverse movement of 1 meter.

lateral shift

is a converging of separate streams into a single stream.

Merge taper

is based on a lateral shift movement of traffic of 0.6 m/s for a through lane merge and 1.0 m/s for an acceleration lane taper. A lateral shift of 0.6 m/s means that for every second of travel in the longitudinal direction, there is a transverse movement of 0.6 meter.

merge taper length

is a very short section of fully constructed shoulder or added lane that is provided to allow slow vehicles to pull aside and be overtaken.
