Transportation Engineering

A district road with a bituminous pavement has a horizontal curve of 1000 m for a design speed of 75 km ph. The super-elevation is

• 1 in 40

• 1 in 50

• 1 in 60

• 1 in 70

The branch of engineering that deals with improvement of traffic performance, traffic studies and traffic network is called ___________

• Highway engineering

• Railway engineering

• Traffic engineering

• Traffic management

Design of horizontal and vertical alignments, super-elevation, sight distance and grades, is worst affected by

• width of the vehicle

• length of the vehicle

• height of the vehicle

• speed of the vehicle

Thickness of a pavement may be reduced considerably by

• compaction of soil

• stabilisation of soil

• drainage of soil

• combination of all the above

Group index method of design of flexible pavement is

• A theoretical method

• An empirical method based on physical properties of sub-grade soil

• An empirical method based on strength characteristics of sub-grade soil

• A semi empirical method

For the movement of vehicles at an intersection of two roads, without any interference, the type of grade separator generally preferred to, is

• delta

• trumpet

• diamond interchange

• clover leaf.

As per recommendations of I.R.C., traffic volume study is carried out for rural roads for 7 days continuously during

• 1.25

• 1.5

• 1.75

• 2.0

Traffic surveys are carried out

• to know the type of traffic

• to determine the facilities to traffic regulations

• to design proper drainage system

• all the above.
