MATHEMATICS, SURVEYING, AND
TRANSPORTATION ENGINEERING
Pier - answer✔any structure built into sea but not parallel to the coastline and includes any stage, stair,
landing place, landing state jetty, floating barge or pontoon and bridge or other works connected
therewith.
guide signs - answer✔Inform and advise road users of directions, distances, routes, the location of
services for road users, and points of interest.
I, II, and III only - answer✔lane line must not be continued on the following cases:
I. across signalized intersections. however, lane lines of low priority road must be discontinued at the
intersection
II. across side street entrances unless the street is one-way street (going in only)
III. past the start of the taper at which a multilane road narrows down.
IV. at approaches to widened or signalized intersection
V. on divided roads
fairway - answer✔an open water with navigable depth
north directions - answer✔This should always be shown on site plans for orientation purposes.
Displaying it prominently is the standard practice.
vertical curve - answer✔They are normally parabolas centered about the point of intersection of the
vertical tangents they join
all of the above - answer✔given the geometric relationships......
calculate the azimuths clockwise and counterclockwise traverse - answer✔procedures for calculating
azimuths clockwise except
II, III, and V only - answer✔While there are differences among a transit, theodolite and a total station, all
theses instruments are designed along the same fundamental relationships or principle lines. the
geometric relationships are as follows
I. the horizontal axis should be perpendicular to the axis of the plate
II. the vertical crosshair should lie in a plane perpendicular to the axis.
III. the lie should be perpendicular to the vertical axis.
IV. the horizontal axis should be parallel to the vertical axis.
V. the axis of the telescope level should be parallel to the line of sight.
III - answer✔which of the following is true
I. all symmetric histograms have single peaks
II. all symmetric bell-shaped curves are normal
III. all normal curves are bell-shaped and symmetric
horizontal control - answer✔this type of control on the object on the job site is commonly identified as
primary, secondary, working
volume - answer✔is the maximum number of vehicles, passengers, or the like, which can be
accommodated by a given facility or system under given condition at a given level of service
breaking wave - answer✔waves which fall forward since the forward velocity of the crest exceed the
velocity of propagation of the wave itself. in deep water, this normally occurs when the wave velocity L
is less than 7 times the wave height
drainage - answer✔is the primary consideration in the design of geometric cross sections for highways,
runways, and taxi ways.
reaction distance and breaking distance - answer✔What are the two components in stoping sight
distance ?
Mean Lower Low Water - answer✔what is the meaning of MLLW
steepness - answer✔The ratio of the wave height to its wave length is called
all of the above - answer✔which of these following statements below best describes the principles of
isosceles and equilateral triangles
I. if two sides of a triangle are congruent, the angles opposite to these sides are congruent
II. if two angles of a triangle are congruent, the sides opposite these angles are congruent
III. an equilateral triangle is equiangular
IV. an equiangular triangle is equilateral
Barriers - answer✔Highway appurtenances designed to prevent vehicular penetration from the travel
way to areas behind the barrier such as to minimize damage to impacting vehicles and their occupants,
and to reduce the risk of injuries to pedestrians and workers.
Flashing Lamps - answer✔Warning devices used to supplement other controls and devices necessary to
alert motorists of construction and maintenance activities or obstructions in the roadway.
Delineators - answer✔Light retro-reflecting devices mounted at the side of the roadway, in series, to
indicate the roadway alignment.
Traffic Cones - answer✔Devices which may be conical in shape or tubular shaped capable of performing
channelization of traffic which may be set on the surface of the roadway or rigidly attached for
continued use.
Temporary Curbing - answer✔Roadwork devices consisting of pre-cast concrete sections, sandbag, and
others which, may be used to guide traffic at the construction site.
Bollard - answer✔Device used in place of rigid barrier posts or traffic cones with a minimum of 450 mm
by 50 mm wide with alternate bands of contrasting color as seen by approaching traffic for delineation
of traffic.
Road Markers - answer✔means any traffic control device marked on the surface of the carriageway
used to regulate traffic or to warn or guide road users.
Risk Assessment - answer✔Looking at the possibility of injury or harm occurring to a person if exposed
to a hazard
Hazard Identification - answer✔Recognizing of things which may cause injury or harm to a person
Risk Control - answer✔Introduction of measures which will eliminate or reduce the risk of a person
being exposed to a hazard
Rule 1080 - answer✔Rule is the guidelines regarding Personal Protective Equipment (PPE)
Accident - answer✔An unexpected event which results in serious injury or illness of an employee and
may also result in property damage
Incident - answer✔An instance of something happening, an unexpected event or occurrence that
doesn't result in serious injury or illness but may result in property damage.
Deep Water Wave - answer✔A wave at a point where the depth is equal to ½ of the wavelength or
greater to be expressed in terms of the parameters of significant wave
Significant Wave - answer✔A hypothetical wave having a wave height and period equal respectively to
average values of the wave height and period of the largest 1/3 of all waves in the train as counted in
the order of greater wave height.
Highest Wave - answer✔A maximum wave height and wave period of the maximum wave height in
wave train.
