railways, roadways
While [] of travel is much to be desired, it is limited by transportation technology, human characteristics, and the need to provide safety
SPEED

- Collector Streets
- Local Streets
DISADVANTAGES OF AIRWAYS
it is most expensive
construction cost is high for airports and
aircrafts
fuel consumption is high
maintenance cost is high for aircrafts
accident causes high loss
Types of Ports
- Major * Intermediate * Minor
URBAN & INTERCITY FREIGHT TRANSPORTATION

ADVANTAGES OF AIRWAYS
it does not require a track
it is useful in military activities
fastest mode of transportation
it is a powerful mean of attack
it helps in aerial photography
BASED ON CARRIAGE WAY
- Paved Roads
- Unpaved Roads
ROAD CLASSIFICATIONS
- National Highway (NH)
- State Highway (SH)
- Major District Road (MDR)
- Other District Road (ODR)
- Village Road (VR)
the application of technology and scientific principles to the planning, functional design, operation, and management of facilities for the mode of transportation in order to provide for the safe, rapid, comfortable convenient, economical, and environmentally compatible movement of
the people and goods
TRANSPORTATION
ENGINEERING
relates more to the ease with which trips are made and the ability of transport systems accommodate all of our travel needs at appropriate times.
CONVENIENCE
AS PER USABILITY
- All Weather Roads
- Fair Weather Roads
TRAFFIC ENGINEERING PROFESSION:
RELATIONSHIP WITH GENERAL PUBLIC, PROFESSIONAL ETHICS
Types of Railway
- Surface * Underground * Elevated
Traffic Control
- Ramp metering
- Signal coordination
- Signal phase sequence
- Left turn treatments
- Parking restrictions
INTERCITY PEOPLE TRANSPORTATION SYSTEM
- Automobile
- Intercity Bus (Point-to-Point Bus)
- Railroad
- Air
- Water
physical characteristics of vehicles and roadways, and influence by our
perception of safety.
COMFORT
According to the [], among the most accident-prone roads in [] are [], [] and [].
MMDA, Metro Manila, AlabangZapote Road, Commonwealth Avenue, Edsa
- Motorcycle,
- Pedestrian,
- Drivers of vehicles with 4 wheels or more,
- 4-wheeled vehicle passengers,
- Cyclists,
- Others,
53%, 19, 14, 11, 2, 1
Types of Airfield
- Flexible (Bituminous) * Rigid (Cement Concrete)
Shifting demand
- Flexible working hours
- Staggered working hours
- Business operating hours
[] and [] of transportation facilities
Safety, security
Reducing demand
- Telecommunicating
- Trip chaining
- Shorter work week
- Residential relocation
- Alternative land use pattern
According to [], assistant secretary for the Department of Transportation (DOTr),
there is a daily average of [] road crashes in [] alone. Vehicles involved are:
Mark De Leon, 262, Metro Manila

THE PRIMARY OBJECTIVE IN TRAFFIC ENGINEERING
safety
ELEMENTS OF TRAFFIC ENGINEERING AND TRAFFIC CONTROL
traffic survey
Harmony with the environment is a complex issue that has become more important over time.
All transportation systems have some negative impacts on the environment. All produce air and noise pollution in some forms, and all utilize valuable land resources.
ENVIRONMENTAL COMPATIBILITY
Types of Airports
- International Airport * Domestic Airport * Military Aerodromes
Air
airways
BASED ON PAVEMENT
- Surface Roads
- Unsurfaced Roads
DISADVANTAGES OF ROADWAYS
carrying capacity is low
speed is low compared to air and waterway
less comfort and safe
uneconomical for long distances
number of road accident is high
Types of Docks
- Wet Dock * Dry Dock
There is little modern transportation systems that can be termed “[]”. Highway and other transportation system involve massive construction, maintenance, and operating expenditures, most of which are provided through general and user taxes and fees. Nevertheless, every engineer, regardless of discipline, is called upon to provide the best possible systems for the money.
CHEAP, ECONOMY
ADVANTAGES OF ROADWAYS
maximum flexibility for travel goods-
it permits any mode of road vehicle
it provides door-to-door service
it saves time for short distance
construction and maintenance cost is low
ELEMENTS OF TRAFFIC ENGINEERING
- Traffic studies and characteristics
- Performance evaluation
- Facility design
- Traffic control
- Traffic operations
- Transportation system management
- Integration of intelligent transportation system technologies (ITS)
Repacking Demand
- Car pooling and van pooling
- Transit
GEOMETRIC ELEMENTS OF
A ROAD
- Camber (Cross Slope)
- Carriageway Width
- Shoulder
- Kerb
- Width Of Roadway
- Right Of Way
- Slight Distance
- Horizontal Curve
- Superelevation
- Gradient
- Vertical Curve
- Alignment
WHERE DO TRANSPORTATION ENGINEERS WORK?
Government

* Philippine National Railways (PNR)
* Light Rail Transit Authority (LRTA)
ADVANTAGES OF RAILWAYS
goods carrying capacity is high
speed is high compared to roadways
cheaper than airways
comfortable for long-distance travel
it increases trade, commerce and business
ADVANTAGES OF WATERWAYS
no need of constructing tracks
it requires cheap motive power
cheapest mode of transportation
it provides efficient mode of defense
it helps in the growth of industries
traffic survey
- Traffic Volume Study
- Spot Speed Survey
