2. Objective You will develop an understanding about Transportation Engineering You will also develop an understanding about overall road development process © S . Das

3. © S . Das 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)

6. Highway Development and Planning 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 © S . Das

7. Highway Development and Planning 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. © S . Das

8. Highway Development and Planning Result 1. Central Road fund was formed in 1928. 2. IRC was formed in 1934. 3. CRRI was formed in 1950. © S . Das

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.

13. Transportation system Diverse characteristics Study context A changing world Role of transportation engineer Basic premise of a transportation system © S . Das

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

15. Transportation system 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. © S . Das

16. Transportation system 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. Change in the demand Changes in the technology Change in operational policy Change in values of the public © S . Das

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 © S . Das

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 © S . Das

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. © S . Das
