Transportation Systems
Transportation Systems
» Definition - A group of components, including inputs, processes, outputs, and feedback used together to move people and goods from one location to another.
Categories
» Land Transportation» Water Transportation» Air Transportation» Space Transportation» Intermodal Transportation
Land Transportation
» The movement of goods and people in a vehicle operating above or under the ground.» Ex. Subways, Buses, Trains, Trucks
and Motorcycles
Land Transportation
» 5 Categories» Rail - Involves vehicles that use rails for
guidance while traveling» Highway - Uses local roads and highways» Pipeline - moves cargo through stationary
pipes» On-site - moves people or cargo short
distances, such as between buildings or complexes
» Recreational - Used for fun, sport, or general leisure.
Water Transportation
» The way in which people and cargo are moved on bodies of water.» Two Forms
» Inland - Canals, Rivers, Lakes» Transoceanic - Across the ocean
Air Transportation
» Movement of people or cargo above the ground and within the earth atmosphere.» Two Types
» Lighter than Air - Vehicles rise and float on their own (Balloons and Hang Gliders)
» Heavier than Air - Requires power to create movement (Airplanes, Jets and Helicopters)
Space Transportation
» The movement of people or cargo within near space and outer space.» Can be manned or unmanned» Ex. Missiles, Rockets, Satellites, Space
Shuttles, and Spacecraft.
Intermodal Transportation
» When more than one of the environments is used (Land, Water, Air, Space) it is considered Intermodal Transportation
» Ex. A container of products may cross the ocean on a ship, be transported inland on a railroad car, and delivered to its destination on a tractor trailer.
Components of Transportation Systems
» The development and use of any transportation system consists of inputs, processes and outputs.
Transportation System Inputs
» Inputs - The various resources needed in order to begin and maintain the use of a system. » People - Serve as both operators and
passengers. » Ex. Repairs, Manual operation, ticket
sales, instrument monitoring
Inputs
» Capital» All the assets used to help operate the system
and the possessions of the transportation company.
» Ex. Vehicles, Roads, Garages
» Knowledge» The information attained through application
and experience of the various tasks performed by people
Inputs
» Materials» The raw materials used in construction and
functioning of a transportation system» Includes iron, wood, fuel, plastic and concrete
» Energy» Provides power and movement to the system» Types include heat, mechanical, chemical,
nuclear, light and electrical.
Inputs
» Finances» All money needed to pay for
equipment, materials, personnel and energy sources.
» Needed for the system to function efficiently and effectively.
Transportation System Processes
» Processes are the on-scene part of the system
» Receiving - The passenger or cargo is physically placed at the location for departure.
» Holding - Place to wait for the transportation vehicle
» Loading - People or cargo are loaded onto the vehicle
Transportation System Processes
» Moving - The actual transporting of people or cargo
» Unloading - Once the destination is reached cargo is removed and passengers exit the vehicle.
End Output
» Transportation System Output - The relocation of people or cargo
