What is Transportation Engineering?
Application of technology and
scientific principals to the
planning, functional design,
operation and management of
facilities for any mode of
transportation in order to provide
for the safe, rapid, comfortable,
convenient, economical and
environmentally compatible
movement of people and goods.
Defined as per ‘Institute of
Transportation Engineer’(ITE)

The first evidence of development in
Indian Subcontinent can be traced
2800 BC from the ancient cities of
Harrapa and Mohenjodaro.
The Grand Trunk Road was built by
Sher Shah Suri in 1540-45

Jayakar Committee
(1928)
1. Road development should be considered as a matter
of national interest.
2. Tax on petrol should be levied to collect fund for
road development work.
3. A semi official technical body should be formed to
act as advisory body on various aspect of road.
3. A research organization should be instituted to
carryout research and development work.

- 11. The evaluation and advancement in Transportation facilities
have been closely linked with the development of human being.
The economic status of any country depends upon the how well
served the country is by different modes of transportation.
For human need all the agricultural or industrial products need
to transport at various stages from production to distribution
Transportation is essential for strategic movement in emergency
for defense of the country and to maintain low and order.

Diverse characteristics
1. Multi-modal- air, land or sea
2. Multi-sector- government, private industry, and public.
3. Multi-problem - national and international policy, carrier
management issues, regulatory, institutional and financial
policies
4. Multi-objective -Aiming at national and regional economic
development, urban development, environment quality, and
social quality.
5. Multi-disciplinary - the theories and methods of engineering,
economics, operations research, political science, psychology,
other natural, and social sciences, management and law.

Study context
1. Planning range - producing long range plans for 5-25 years
2. Passenger transport - Regional passenger transportation,
dealing with inter-city passenger transport by air, rail, and
highway and possible with new modes.
3. Freight transport - Routing and management, choice of
different modes of rail and truck
4. International transport - Issues such as containerization, inter-
modal co-ordination.

A Changing World
The strong interrelationship and the interaction between
transportation and the rest of the society especially in a rapidly
changing world is significant to a transportation planner.
1. Change in the demand
2. Changes in the technology
3. Change in operational policy
4. Change in values of the public

- 17. Transportation system
Role of transportation engineer
The transportation system analysis approach is to intervene,
delicately and deliberately in the complex fabric of society to
use transport effectively in coordination with other public and
private actions to achieve the goals of that society.
requires understanding of the basic theoretical concepts and
available empirical knowledge

- 19. Advantage in Road Transport
Among all road transportation is nearest to the people
Low Capital Investment
Flexible Service
More freedom to users while travelling
Ability to accommodate various types of vehicle at a time
Quick and assured door to door service
Faster and cheaper service particularly for short distance
travel

- 20. What is Highway Engineering?
The road pavement are generally constructed on low embankments,
above the general level or adjoining land, whatever possible in
order to avoid the difficult drainage and maintenance problems.
The term road or roadway thus constructed is therefore termed
‘Highway’.
The Science and Technology dealing with roads is generally called
Highway Engineering.
