3. What is
Transportation
Engineering?
Transportation
Engineering is a branch
of Civil Engineering that is
involved in the planning,
design, operation, and
maintenance of safe and
efficient transportation
systems. These systems
include roadways, railways,
airways and waterways.

4. Role of Transportation
Every product needs
transportation
Better system can
provide easy access and
benefit to low costing
of products.
Availability of raw
material can be
provided to
manufacturing units.
People of remote area
can come closer to the
city or town.
People from different
parts of country can
reach far places with
convenience and in less
time.

5. Role of Transportation in National
Development
Economic
Growth.
Place utility
of goods.
Time utility
of goods.
Mass
Production.
Exploitation
of natural
resources.
Urbanization
Industrial
Development.
Agriculture
Development.

6. Transportation
Ways
1. Railways
◦ Surface
◦ Underground
◦ Elevated
◦ LRT (Light Rail Transit)
2. Roadways
3. Airways
4. Water Ways

7. Surface Transportation & Aviation

8. Modes of Transportation :-

9. Roadways
◦ CLASSIFICATION OF ROADS-
1. Express Ways
2. National Highway
3. State Highway
4. Major District Road (MDR)
5. Other District Road (ODR)
6. Village Road (VR)

11. 1. Express Ways
◦ These are suggested in Third Road development plan (1981-
2001).
◦ These are used to connect the Metropolitan cities like Mumbai,
Delhi, Lucknow, Kolkata, Chennai.
◦ They have the highest design speed.
◦ They should have at least four lanes.

12. • Express Ways in India
◦ Purvanchal Expressway- 6 Lane, 340 Km
◦ Delhi-Mumbai Expressway- 8 Lane, 1350 Km (Under Construction)
◦ Agra- Lucknow Expressway- 6 Lane, 302 Km
◦ Mumbai-Pune Expressway- India’s first 6 Lane, 93 Km
◦ Jaipur-Kishangarh Expressway – 6 Lane, 90 Km
◦ Ahemdabad-Vadodara Expressway – 95 Km
◦ Delhi-Gurgaon Expressway- 28 Km,
◦ Western Expressway- 10 Lane, 25.33 Km
◦ Eastern Expressway- 6 Lane, 23 Km
◦ Yamuna Expressway OR Taj Expressway- 6 Lane, 165 Km
◦ Noida-Greater Noida Expressway- 6 Lane, 24Km

13. 2. National Highways
◦ They run through the Length and Breadth of the country.
◦ They connect national capital to all state capitals, major cities,
towns, border areas.
◦ They should have at least two traffic lanes, good surface
finishing and excellent strength to carry heavy traffic.
◦ The construction and maintenance of these roads is usually
carried out by Central government.

14. 3. State Highways
◦ These are main roads running within the states They connect
important towns, cities of state with National Highway.
◦ These are generally one lane but two lanes are always be
preferred.
◦ They have modern type of bituminous or Concrete surfacing.
◦ The construction and maintenance of these roads are usually
carried out by the State Government.

15. 4. District Roads
1. Major District Road-
◦ These roads connect all the districts, all production areas and
markets with State Highway or National Highway or Railways.
◦ They have single metalled lane of traffic.
2. Other District Road-
◦ These provide links to villages and serve a large rural
population.
◦ They should have good metalled surface and proper drainage.
◦ Construction and maintenance are carried by District
Authority or Zila Parishad (Z.P.).

16. 5. Village Roads
◦These connect the villages with each other and also
towns nearby.
◦These are generally established earth roads but metal
surface is preferred.
◦The construction and maintenance are carried by local
District boards.

17. Definition of Geometric Design :
◦ Geometric design of highways deals with the dimensions and
layout of visible features of the highway.
◦ Geometric design fulfills the requirements of the driver and the
vehicle, such as comfort, efficiency and safety.
◦ Proper geometric design will help in the reduction of accidents
and their severity.

18. Road Alignment :
Alignment : is an arrangement in a straight line or in correct
relative positions.
◦ The position or the layout of the central line of the highway on
the ground is called the alignment.
◦ Horizontal alignment includes straight and curved paths.
◦ Vertical alignment includes level and gradients.

19. Elements of Road :

20. Cross-Section of Road :

21. • Carriage Way :
◦The Width of pavement way on which vehicles
travel is called carriage way.

22. • Road Shoulders :
◦ Shoulders are provided along the road edge to serve as an emergency
lane for vehicles.
◦ As per IRC, the min. width of shoulder should be 2.5m.
Uses :
◦ Repair of broken down vehicles
◦ Overtaking operations
◦ To act as an emergency lane
◦ For future widening of Road

23. • Formation width :
◦ Formation width is the top width of the highway embankment or the
bottom width of cutting excluding the side drain.
◦ Formation width = Width of Carriage Way + Width of shoulder

24. • Right of way :
◦ Right of way is the area of land acquired for the land , along its alignment.
◦ It is the distance between boundary stones of road on either side of road.

25. • Side slope :
◦ The slope of earthwork in Filling ( embankment ) or
cutting is called side slope.

26. • Berm :
◦ The distance between the road toe and inner edge of borrow
pit is called berm.
◦ It prevents the erosion of embankment soil.

27. • Side Drain :
◦ For the drainage of rain water, drains are provided on either
side of the road.
◦ Normally, Side drain are required for road in cutting.
◦ For road in embankment side drain is not necessary.

28. • Kerbs :
The boundaries between pavement and shoulders
or footpath are known as kerbs.

29. • Pavement Design :
◦ A highway pavement is a structure consisting of superimposed layers of
processed materials above the natural soil sub-grade.
◦ The pavement must provide an acceptable riding quality, adequate skid
resistance, favourable light reflecting characteristics, and low noise
pollution.

30. Cross section of different types of road as
per IRC :

31. • Cross-Section of of highway in urban
areas

32. • Camber
◦ Camber or cross slope is the slope provided to the road surface in
the transverse direction to drain off rain water from the road
surface.
◦ The rate of camber is usually designated by 1 in n (1 vertical to n
horizontal)

33. Advantages & Disadvantages of Roadways
