Chapter 4: Transportation Enginering

• 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.
• Transportation Engineering

  • Defined as that phase of engineering which deals with safe and efficient movement of people and goods on streets and highways; or
  • Defined as that phase of transportation engineering which deals with the planning, geometric designs and traffic operations of roads, streets and highways, their networks, terminals, abutting lands, and relationships with other modes of transportation.
• Important Goals of Transportation Engineer

  1. Provide a high Level of Service (LOS) = by minimizing travel time and delays
  2. 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: EXAMPLE

  • tunnels
  • interchange
  • bridge
  • viaduct
  • modern underpass
  • pedestrian facilities
  • traffic operations and control
• ROAD TRANSPORT: OTHER AREAS OF CONCERN

  • congestion
  • pollution
  • accidents
  • social issues of accessibility 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: ADVANTAGES

  •Dependable

  •Better Organized

  •High Speed over Long Distances

  •Cheaper Transport

  •Safety

  •Larger Capacity

  •Environment Friendly
• WATER TRANSPORT

  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 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: CLASSIFICATION

  • Inland Water Transport (IWT)
  • Shipping
  • Coastal shipping
  • Overseas shipping
• WATER TRANSPORT: ADVANTAGES

  1.Cheapest traffic means

  2. Possesses high load carrying capacity

  3. Requires cheap motor powers than for airplanes

  4. Does not require any special infrastructure like roads, and airports

  5. Environment-friendly
• WATER TRANSPORT: DISADVANTAGES

  1.Slow in speed

  2. More chances of attack on boat sailing through

  3. Only can be used when sufficient water is available

  4. Does not work well in water bodies with high drafts (e.g. near waterfalls)

  5. Highly weather susceptible
• PIPELINE TRANSPORT

  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.
• CAREER OPPORTUNITIES: TYPES OF TRANSPORT ENGINEERS
