HIGHWAY AND RAILROAD

ENGINEERING

TRANSPORTATION

• the act or process of moving people or things from one

place to another

• a way of travelling from one place to another
• a system for moving passengers or goods from one place to

another

TRANSPORTATION ENGINEERING

• It is 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 the safe, efficient, rapid, comfortable, convenient, economical and environmentally compatible movement of people as well as goods.

IMPORTANCE OF TRANSPORTATION

Social Costs and Benefits of Transportation

• The history of transportation illustrates that the way

people move is affected by technology, cost, and

demand.

• The specialties in transportation engineering are planning,

design, construction, traffic management and operations,

and maintenance.

Transportation Engineering Specialties

• Planning involves the selection of projects for design and

construction

• Design involves the specification of all features of the

transportation project

• Construction involves all aspects of the building process
• Traffic management and operations involves studies to

improve capacity and safety

• Maintenance involves all work necessary to ensure that the

highway system is kept in proper working order

TRANSPORTATION SYSTEM

• Transportation systems are complex, dynamic and internally interconnected, as well as interconnected with other complex dynamic systems (e.g., the environment, the economy)
• A transportation system may be defined as a planned network of elements or physical components that play different roles in the transportation of goods and persons from one place to another.

COMPONENTS OF TRANSPORTATION SYSTEM

COMPONENTS OF TRANSPORTATION SYSTEM

1. MODES

They represent the conveyances, mostly taking the form of

vehicles that are used to support the mobility of passengers or

freight. Some modes are designed to carry only passengers or

freight, while others can carry both.

AIR TRANSPORT

As experienced during 9 / 11 and other terrorist threats the consequences of failing security are devastating. Air traffic is therefore extremely well monitored, both in terms of passengers or freight as in terms of routing and operations management. Example: Hot Air Balloons, Airplanes, Helicopters MODES OF TRANSPORT
