Transportation Technology

Learning StandardsLearning Standards6. Transportation Technologies Transportation technologies are systems and devices

that move goods and people from one place to another across or through land, air, water, or space.

6.1 Identify and compare examples of transportation systems and devices that operate on or in each of the following: land, air, water, and space.

6.2 Given a transportation problem, explain a possible solution using the universal systems model.

6.3 Identify and describe three subsystems of a transportation vehicle or device, i.e., structural, propulsion, guidance, suspension, control, and support.

Learning ObjectivesLearning ObjectivesAt the conclusion of the lesson the student will be

able to:

1) Define Transportation technology

2) Compare & contrast land, air, water & space transportation

3) Use the Universal Systems Model of technology to explain a transportation system

4) Describe a transportation system & it’s subsystems

Transportation Technology

System: A group of parts that work together in an organized way to complete a task

Systems & devices that move goods & people from one place to another across or through…

Land

Air

Water

Space

Land TransportationPersonal Transportation

Cars, Motorcycles, Bicycles

Moves individuals or small groups of people

People purchase & maintain their own vehicles

People control their own schedules

Mass Transportation

Buses, Trains, Subways

Moves many people at one time & available to the general public

Companies purchase & maintain the vehicles

Operates on a set schedule

Mass TransportationTradeoffs of using Mass Transportation:

Mass Transportation is not as popular in the US as in other countries

Positives

Reduces Traffic

Saves fuel

Better for environment

Negatives

Slower

Less convenient

Less personal freedom

Railroads earn most of their money transporting freight

Trains

Large/heavy items are usually carried by train

Trains also carry passengers

Intercity passenger railroad in the US is operated by AMTRAK

Less than 1% of all intercity passengers in the US travel by train

Trains

In some countries - trains carry up to 50% of intercity passengers

Trains

Maglev TrainsMagnetic Levitation - Train doesn’t touch the track - no wheels

Propelled by magnets

Floats 1 inch above it’s track so it provides a very smooth, quiet, fast ride (270 MPH)

Transport much of our country’s freight

Trucks

Most convenient way to transport goods

Water Transportation

Water has been used to transport people and cargo for centuries

Ships

Ships transport most of the overseas cargo leaving or entering the US

Water transportation is usually the least expensive way to transport goods

Air Transportation

December 17, 1903Kitty Hawk, North Carolina

First manned airplane flightWright Brothers

Air TransportationAir is the most complex transportation system because so many planes are in the air at one time

The government controls air travel (FAA)

Air travel has become so popular that planes have been built to carry 500+ passengers

Passenger Planes

Cargo PlanesSome planes carry only cargo

Air transportation is the most expensive way to transport goods

HelicoptersAircraft with one or two rotors that allow it to lift straight up

Helicopters can reach places that other types of transportation cannot

Used for: • Pipeline inspections

• Checking auto traffic

• Transporting people to hospitals

Space TransportationNASA is responsible for regulating and directing the entire US space program

Currently consists primarily of unmanned exploration vehicles

Exploratory VehiclesCurrently, exploratory missions are being done without human crews

They carry cameras & other exploratory equipment

Using 2 or more forms of transportation to move people or cargo more efficiently

Examples:

Bus or car to airport - plane to a coastal city – bus or taxi to dock - then board a cruise shipCargo is loaded into containers and placed on a ship - then loaded onto a train - then transferred for travel by truck

Advantage:

Saves time and money because it is very efficient

Intermodal Transportation

Transmission Transfers power fromthe engine to theaxles and wheels:

Structure and support:

Brakes & Steering

Navigation:

Automobile SubsystemsWhen all subsystems work together the car functions properly

Universal System Model

Goal:Goal: What you want the system to doResources: People, tools & machines, information, time, capital, energy, materials

The steps that lead to a result

The result that comes out of the

system

FeedbackComparing the result to the original need; adjustments are made to the inputs and/or

processes

Can be used to describe a Transportation System

Have inputs, process, outputs & feedback

Feedback:

Goal (Safe arrival at scheduled stops), Buses, people to operate buses, fuel to provide energy, schedules, passengers

Loading passengers, driving the bus

Safe arrival at scheduled stops

Comments from satisfied customers

Transportation Systems

We can use the Universal Systems Modelto describe any of these

Transportation Systems as well
