Transportation Technology

Introduction to Technology

Objectives of Lesson…

•Define Transportation technology

•Identify the four major categories of transportation technology

•Compare the six technologies that are part of transportation technology

•State the importance of using transportation within our society.

What is Transportation?

Definition:

•Technology

•Used to move people and products

•Within Society

So, transportation is technology that is used to move people and products within a society.

??What Might the History of Transportation Be??

Modes of Transportation…

Considering our definition, what are all the modes of transportation you can think of?

Industry associated with Transportation careers….

•Trucking Automotive Railroad

•Bus Companies City Transportation

•Road Construction Harbor and Marine

•Flight and Navigational Airports Pipelines

•Manuf for transportation Airlines

•Leisure Boating Recreational Products

Categories of Transportation

Categories are based on the environment in which the transportation technology is used.

4 Main Categories…4 Main Categories:

1. Land-any transportation that is used on or under land to transport people and products or goods.

2. Marine-transportation by water.

3. Atmospheric-vehicles that operate primarily in the earth’s atmosphere.

4. Space-any form of transportation that reaches beyond the earth’s atmosphere.

Land Transportation…

Forms:

•autos, buses, railroads, escalators, conveyers, and pipelines

Subdivided into fixed and random routes-

•random-not fixed on one path (bicycle)

•Fixed-those that fixed to one path (conveyor system)

3 Major Types:

Highway systems, Rail systems, Continuous Flow Systems

What Major Invention that Made Trains and Railroads Possible???

Steam Engine

Question????

Are there any forms of land transportation that are for fun only?

What are their routes? Fixed or random?

Marine Transportation…

5 US Regions for Marine Transportation-

•Great Lakes System and St. Lawrence Seaway

•Mississippi River System

•Pacific Coast Waterways

•Gulf Coast Waterways

•Atlantic Coast Waterways

Includes:

•Large lakes, inland lakes, oceans, seas, rivers

??How Did Early Boats Move Through the Water??

Paddles, Wind on the Sails

Atmospheric Transportation…Usually remain the earth’s atmosphere

Includes:

1. Lighter than air-

• Balloons

• Airships

2. Heavier than air-

• Passenger planes

• Cargo planes

• Military planes

Space Transportation…Types:

1. Manned-

• Vehicular Units

• Shuttle Units

2. Unmanned-

• Missiles

• Satellites

• Space Probes

Transportation System Components

Three Major Components within each of the Transportation Systems

1. Pathways

2. Vehicles

3. Support Structures

Pathways…

In order to deliver products and people from one location to distant locations, a network of pathways must exist.

Land Pathways-

•easy to see

•roads, highways, rail lines and pipelines

Water Pathways-

•less visible

•includes all navigable bodies of water

Vehicles…

All transportation systems, except continuous flow systems, use vehicles.

Vehicles-technological devices designed to carry people and cargo on a pathway. Designed to contain and protect the cargo they carry.

Support Structures…All transportation systems use human built structures.

Includes:

Rail lines

Canals

Pipelines

Terminals-

1. Where transportation activities begin and end

2. Used to gather, load and unload passengers and goods

Systems of Technology

Technological Systems in Transportation…

6 Basic Systems:

1. Propulsion

2. Suspension

3. Guidance

4. Control

5. Support

6. Structure

Propulsion Systems…

All vehicles used for transportation must have some kind of propulsion system.

Autos use-?

Gasoline or diesel engines

Trucks use-?

Diesel engines

Aircraft use-?

Piston and jet engines

Suspension Systems…

No matter what type of transportation mode, the vehicle weight must be supported.

3 Types of Suspension Systems:

Mechanical-shocks, air suspension, wing design

Fluid-hull design

Magnetic-magnetic levitation

Guidance Technology…

Guidance systems provide information to direct a vehicle. All transportation systems must have some form of guidance technology.

Devices for Guidance Include:

1. Tachometers, airspeed indicators, inertial sensors, radar, rails

Control Technology…

Includes:

1. Total traffic-traffic lights, airport control towers, railroad control towers

2. Vehicle control-force to change, alter or regulate the speed, direction and attitude of the vehicle. Includes brakes, cruise controls, etc.

Support Technology…

Support technology – systems of technology used for processing the vehicle, moving passengers to and from the vehicle and bringing freight to and from the vehicle.

Includes:

1. Airports 4. Gasoline stations

2. Marinas 5. Parts dealers

3. Launch pads

Question???

Why is “support technology’ a limitation in developing new forms of transportation?

Support systems are not in place for the transportation designs of the future

Structure Technology…

Used to make vehicles lighter, stronger and more heat resistant.

Questions:

What are the three parts of a transportation System

What are the 6 systems involved in transportation?

Activity:

1. Select a transportation system you use and describe it in terms of:

• Pathway

• Vehicle

• Structures used
