CEOR - TRANSPORTATION ENGINEERING Flashcards
It is the means by which these activities occur, it is the cement that binds together communities and their activities.
Transport
Because of its pervasive nature, occupies a central position in the fabric of a modern-day urbanized
nation.
Transport
These are composed of networks of interconnected facilities and services.
Transportation systems
It deals with the efficient transport of people and goods.
Transportation Engineering
It applies technological and scientific principles to the planning, functional design, operation and management of facilities for any mode of transport in order to provide for the safe, rapid, comfortable, economical, environmentally compatible movement of people and goods
Transport Engineering
A branch of transport engineering that deals with the planning, geometric design, traffic operation roads, street, and
Traffic Engineering
It is mostly government funded or at least government approved.
Transportation Infrastructures
It considers policy information processes, cost, financing, and projected performance of potential transportation systems, including Intermodal Transportation.
Transportation Planning
What are the three elements of transportation?
Vehicle
Path
Terminal
over which the vehicles travels (roads, airport runway, and railway track) is built and maintained
by civil engineers
Path
It is where the passengers and cargo are serviced, are planned, constructed and maintained by civil engineers (bus stands, truck depots, railways stations, air terminals, docks and harbors)
Terminals
It constructed roads, railways lines, docks, harbors, and airports, which facilitated the movement of goods and passengers.
Government
It includes fatalities, injuries, and property damage due to accidents
Safety
Optimal allocation of resources in moving people and goods; access, provision of enabling technologies and services to people that need to reach and use opportunities.
Efficiency
Travel in environments without causing unnecessary stress and strain due to noise or other factors.
Comfort
Production of contaminants in the air, water, or soil that are at a higher levels than naturally found.
Environmental Pollution
Entails the efficient management and operation practices, design, and assessment of the cost effectiveness of transportation systems.
Transportation System Engineering
A function of land use.
Traffic
This activity is crucial to the transport planning process, as the data form the basis for formulation plans.
Transportation Survey
It sometimes is considered as synonymous to transportation engineering but is usually defined as the narrower field of management of traffic flow.
Traffic Engineering
They se projected and monitored traffic patterns and volume to design automated or centrally controlled street signal to modulate traffic.
Traffic Engineers
For triggering of left-turn signal.
Weight Sensors
For freeway entry during rush hours.
Ramp-entry signals
These are installed along travel routes to ensure safe, orderly, and predictable traffic movement. They provide guidance and warning to the motorists.
Traffic Control Devices
It was developed to promote uniformly in traffic control devices.
Manual on Uniform Traffic Control Devices (MUTCD)
It include right-of-way (stop and yield), speed, movement (directional), parking, pedestrian,
and other special signs. A specific code is assigned to each type of sign on the street plans for easy recognition.
Regulatory Signs
Alerts drivers to any potentially hazardous condition on or adjacent to the roadway provide a signal to reduce speed or drive safely.
Warning Signs
These are used to indicate intersections, traffic signals, changes in grade, entrances, and crossings.
Warning Signs
Indicate routes and direct travelers to cities, places of interest, parks, forests, and historical sites. Most guide signs vary in size and usually feature white messages on a green background
Guide Signs
For general motorist services are white messages on a blue background. These have a white symbol on a brown background.
Recreational and Cultural Signs
Usually black text on an orange background. These follow the basic standards of shaped and other details for all highways
Construction and Maintenance Signs
Provided on the road pavement (carriageway markings) or on object which are part of the road. These are painted with hot applied thermoplastics paints
Road Markings
It is a problem which has to be addressed by the traffic engineer
Parking
Needed for guiding roads users to see the carriageway and the immediate surroundings clearly.
Street Lighting
Emissions caused by the exhaust of vehicles contain major pollutants like carbon dioxide, carbon monoxide, lead compounds, smoke, and unburnt petrol.
Air Pollutions
It can be controlled by reducing the use of private vehicles, frequent checking of vehicle emissions, and use of battery operated vehicles.
Air Pollution
It used to measure noise levels.
Decibels
It can be controlled by changes in the design of vehicles, changes in tires or road surfaces and modifications in traffic operations.
Noise
It cause by the movement of vehicles on narrow streets flanked by building.
Vibration
It is caused by roadside advertisements, unregulated parking and ribbon development along highways.
Visual Intrusion
It caused when a road is aligned through a village of habitation, dividing the life of the community, forcing them to cross the road and risking their safety.
Severance
Focuses on planning, design, construction, and operation and maintenance of highways
Highway Engineering
Refers to the highways systems of the Philippines
The Philippine Highway Network
A network of national roads owned and maintained by the DPWH.
The Philippine Highway Network
Roads which form parts of the main trunk line system and directly connect three of more major cities and metropolitan areas with a population of at least 100,000.
National Primary
Roads that complement the primary roads and provide access to other major population centers. They directly link smaller cities to the primary roads.
National Secondary
Introduced on 2014 and they include other existing roads administered by the DPWH which perform a local function.
National Tertiary
The retina perceives objects very sharply within a zone formed by a cone whose angles is 3 degrees about the center of the retina.
Acute Vision or Visual Acuity
Deals with the visual zone for the two eyes.
Peripheral Vision
An important factor in highway design. It governs the perceiving of information, analysing, starting the decision making process, and the will to react to a situation
PIEV (Perception, Intellection, Emotion, Volitions)
When a vehicle is moving on a curved path, it is subjected to an outward force.
Centrifugal Force
One of the important considerations in designing a highway.
Gradient
The distance required by a driver of a vehicle Travelling at a given speed to bring his vehicle to a stop after an object on the roadway becomes visible.
Stopping Sight Distance
The time lag or the brief interval between the perception of danger and the effective application of brakes.
Brake Reaction Time
This become necessary because some vehicles travel fast while some travel slow.
Overtaking
Remains a cost-effective way of transporting large quantities of goods on land.
Railway Transportation
It focuses on planning, design, construction, operation, and maintenance of railways.
Railway Engineering
The passenger coaches and good wagons.
Containers
The locomotive, which may be a steam engine, diesel, or an electric.
Propulsion Unit
The railway track on which the trains move.
Pathway
The railway station and goods yard where passengers and goods are serviced.
Terminal
Two steel rails separated at a distance
Gauge
The subject of dimensioning of the visible elements of the track.
Geometric Design of Railway Track
Distinguishing the permanent track from the track constructed temporarily for transporting materials to construction sites and dismantled later.
Permanent Way
It consists of the earthen formation over which the track structure is laid.
Permanent Way
The embankment constructed on the natural ground to accommodate the railway track.
Formation
Based on the movement of steel wheels of locomotives, coaches, and wagons on steel rails.
Railway Technology

Invaluable for the defense of the country
Military Use
In times of natural and man-made calamities, air transport will be providing these to affected people and rescue them safely.
Relief and Rescue Operations
Some areas in the Philippines are difficult to access by road, since Philippines is an archipelago, some island are only accessible via air transport.
Accessibility to Remote Areas
Air transport is very safe compared to road transport and railways.
Safety
The only fuel for aircraft now is petroleum crude-based aviation petrol.
High Consumption of Liquid Fuel
