Lesson 2 Flashcards
all about moving goods and people from one place to another. It is also Safe, efficient, reliable, and sustainable movement of persons and goods over time and space
Transportation
type of civil engineering which focuses on the infrastructure of transportation: all the elements which support the movement of goods and people
Transportation Engineering
Application of technology and scientific principles to the planning, functional design, operation, and management of facilities in order to provide safe, rapid, comfortable, convenient, economical, and environmentally compatible movement of people and goods.
Transportation Engineering
Plays a major role in the development of the human civilization.
Transportation
A transportation solution should be …
Safe
Rapid
Comfortable
Convenient
Economical
Eco-Friendly for both men and material
The solution to transportation problems must be:
- Analytically Based
- Economically Sound
- Socially Credible
- Environmentally Sensitive
- Practically Acceptable and Sustainable
Characteristics of Transportation System
- Multi-modal
- Multi-sector
- Multi-problem
- Multi-objective
- Multi-disciplinary
Covering all modes of transport
Multi-Modal
Encompassing the problems and viewpoints of government, private industry, and public
Multi-sector
Aiming at national and regional development, urban development, environment quality, and social quality, as well as service to user and financial and economic feasibility.
Multi-objective
Drawing on the theories and methods of engineering, economics, operations research, political science, psychology, other natural, and social sciences, management and law.
Multi-Disciplinary
Ranging across a spectrum of issues that includes national and international policy, planning of regional system, the location and design of specific facilities, carrier management issues, regulatory, institutional and financial policies
Multi-problem
The context in which transportation system is studied
- Planning range
- Passenger transport
- Freight transport
- International transport
Refers to urban transportation planning, producing long range plans for 5-25 years for multimodal transportation systems in urban areas as well as short range programs of action for less than five years.
Planning Range
Refers to routing and management, choice of different modes of rail and truck.
Freight transport
Refers to issues such as containerization, inter-modal co-ordination
International Transport
Refers to regional passenger transportation, dealing with inter-city passenger transport by air, rail, and highway and possible with new modes.
Passenger Transport
Three elements of Transportation System
- Infrastructure (includes roads, canal, rail)
- Vehicles (includes planes, trains, ships)
- Operators/Content (includes, drivers, pilots, passengers)
Major Disciplines of Transportation
- Transportation Planning
- Geometric Design
- Pavement Design
- Traffic Engineering
Essentially involves the development of a transport model which will accurately represent both the current as well as future transportation system.
Transportation Planning
Deals with physical proportioning of other transportation facilities, in contrast with the structural design of the facilities. The topics include the cross-sectional features, horizontal alignment, vertical alignment and intersections.
Geometric Design
Deals with the structural design of roads, both (bituminous and concrete), commonly known as (flexible pavements and rigid pavements) respectively.
Pavement Design
Covers a broad range of engineering applications with a focus on the safety of the public, the efficient use of transportation resources, and the mobility of people and goods; involves a variety of engineering and management skills, including design, operation, and system optimization.
Traffic Engineering
Other Important Disciplines
- Public transportation
- Financial and economic analysis
- Environmental impact assessment
- Accident analysis and reduction
- Intelligent transport system
