What office is responsible for zoning of their respective jurisdictions and final land use and zoning planes to be submitted to HLURB (Housing and Land Use Regulatory Board) for approval?

• Provincial Planning Development Office (PPDO)

• City Planning Development Office (CPDO)

• Municipal Planning and Development Office (MPDO)

• All of the above

Ideal Capacity of a road is:

• 1800 vehicles/hr

• 2000 vehicles/hr

• 1400 vehicles/hr

• 1200 vehicles/hr

The required length of the turnout shall be determined considering a length of _____ meters for each bus.

• 16.0

• 15.5

• 15.0

• 14.5

The length of superelevation development from the normal cross slope to the zro cross slope point on the tangent is known as:

• tangent runoff

• tangent runout

• super elevation runout

• super elevation runoff

Criteria used for the establishment of sag vertical curves:

I. Headlight sight distance

II. Passenger comfort

III. Drainage control

IV. General appearance

V. Velocity of cars passing thru the curve

• I, II, IV and V only

• I, II, III and IV only

• II, IV and V only

• All of the above

They are essential part of any road that is not on fill and must be incorporated into the road cross-section. These are designed to accommodate the expected rainfall but can often be hazardous to vehicles that run off the road.

• transverse drainage ditches

• shoulder

• drop curve and gutters

• longitudinal drainage ditches

The most important criteria to consider to avoid safety hazards created by the drainage ditches is the actual reconnaissance survey during wet whether to identify the natural run-out locations. Slopes on the side nearest the road should not be steeper than _____ and preferable flatter as this will minimize accident severity. The slope farthest from the road may be as steep as the ground will permit.

• 4:1

• 3:1

• 2:1

• 1.5:1

What are the components in stopping sight distance?

I. Reaction distance

II. Braking distance

III. Height of driver’s eye above the roadway

IV. Height of object

• I, II and IV only

• I, II and III only

• I and II only

• All of the above

The speed limit appropriate on a high standard duplicated carriageway road where there is only occasional access from adjoining properties is:

• 50 kph

• 30 kph

• 60 kph

• 80 kph

It is 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.

• Density

• Free Flow

• Road Capacity

• Flow of Traffic
