Chapter 4 Flashcards
Transportation Engineering (36 cards)
A sub-discipline within Civil Engineering. Grown to become a substantial multidisciplinary and interdisciplinary field of study.
Transportation Engineering (TE)
State the Definition of Transportation Engineering
The application of technology and scientific principles to the planning, functional design,
operation, and management of facilities for any
mode of transportation in order to provide for
safe, rapid, comfortable, convenient,
economical, and environmentally compatible
movement of people and goods.
IMPORTANCE AND VITAL ROLE OF
TRANSPORTATION
Transportation move people and goods to different
neighborhoods, cities, states, and countries.
Society depends on good transportation – along
with other social systems
IMPORTANT GOALS OF TRANSPORTATION ENGINEER (LOS 1 - DESC)
Provide a high Level of Service (LOS)
= by minimizing travel time and delays
IMPORTANT GOALS OF TRANSPORTATION ENGINEER (LOS 2 - DESC)
Provide high Level of Safety (LOS)
= by minimizing accident and harmful effects to the environment
GENERAL MODES OF TRANSPORT
Road transport
Air transport
Railway transport
Water transport
Pipeline transport
ROAD TRANSPORT: AREAS OF CONCERN
- Planning of street and highway facilities
- Design of geometric configuration of street and highway facilities
- Construction streets and highways
- Traffic operation and control
- Traffic safety
- Maintenance of traffic facilities and controls
- Management of traffic facilities and controls
ROAD TRANSPORT: AREAS OF CONCERN - APPLICATION
Tunnels
Interchange
Akashi Kaikyō Bridge
Millau Viaduct
Modern Underpass
Pedestrian Facilities
Traffic Operations and Control
Road Transport Example (Bridge)
Akashi Kaikyō Bridge
Longest span: 1,991 metres (6,532 ft (1.237 mi))
Road Transport Example (Viaduct)
Millau Viaduct :343 meters (1,125 ft)
OTHER AREAS OF CONCERN IN TRANSPORTATION
ENGINEERING
Congestion
Pollution
Accidents
Social Issues of Accesibility and Mobility
AIR TRANSPORT: AREAS OF CONCERN
To meet and address the ever-changing demand and challenges in the aviation industry in so far as planning, design, and maintenance of Airport facilities such as Runways, Taxiways, Apron Gates and Terminal processing area.
AIR TRANSPORT: OBJECTIVES
- EXPLAIN THE DIFFERENT AIRCRAFT SYSTEM COMPONENTS
- DISCUSS THE AIRCRAFT CHARACTERISTICS AFFECTING THE DESIGN OF AIRPORTS
- DISCUSS THE FACTORS AFFECTING PLANNING AND DESIGN OF AIRPORT TERMINAL
- DISCUSS THE DIFFERENT AIRPORT RUNWAY
CONFIGURATIONS - DESIGN FLEXIBLE AND RIGID PAVEMENT OF
RUNWAYS AND TAXIWAYS
RAILWAY ENGINEERING: SIGNIFICANCE
It is very important for civil engineering students into the field of railways to be aware of not only the fundamentals of railway engineering but also the latest developments with regard to railway tracks, locomotives and rolling stock, signaling, and interlocking, etc.
ADVANTAGES OF RAILWAY TRANSPORT
- Dependable
- Better Organized
- High Speed over Long Distances
- Cheaper Transport
- Safety
- Larger Capacity
- Environment Friendly
HISTORICAL NOTES IN RAILWAYS
- More than a thousand routekilometers were built before the war
- Only 452 route-kilometers were operational after it.
- only less than 30km remain operational excluding LRT Lines
- Now only a total of 75.2 routekilometer of railway network.
Is defined as the process of moving people,
freight and mails by barge, boat, ship or sailboat
over a sea, ocean, lake, canal and river or by
other types of water transportation
WATER TRANSPORT
WATER TRANSPORT INCLUDES
- Natural modes such as navigable rivers
- Artificial modes such as canals.
- Including rivers and canals, represents an Important, alternative and environmentally friendly way of transporting goods and passengers.
Water Transport can be Broadly
Classified as:
- Inland Water Transport (IWT)
- Shipping
Shipping is divided into two categories
- Coastal shipping
- Overseas shipping
IS AN EXTREMELY CRUCIAL AND FAMOUS SHIPPING CANAL ALLOWING THE PASSAGE OF VESSELS BETWEEN THE MEDITERRANEAN AND THE RED SEA.
THE SUEZ CANAL
ADVANTAGES OF WATER TRANSPORT
- Cheapest traffic means
- Possesses high load carrying capacity
- Requires cheap motor powers than for airplanes
- Does not require any special Infrastructure like roads, and airports
- Environment-friendly
DISADVANTAGES OF WATER TRANSPORT
- Slow in speed
- More chances of attack on boat sailing through
- Only can be used when sufficient water is available
- Does not work well in water bodies with high drafts (e.g. near waterfalls)
- Highly weather susceptible
This system of transportation involves the use of hollow pipes in the transportation of water, crude oil, (petroleum) and gas. This mode of transportation is safer than using tankers or trailers in the transportation of these liquids.
PIPELINE TRANSPORT
