Test: Highway Geometric Design - 3 - Question 1

If an ascending gradient of 1 in 50 meets another ascending gradient of 1 in 30 then the deviation angle is

Detailed Solution for Test: Highway Geometric Design - 3 - Question 1

Test: Highway Geometric Design - 3 - Question 2

The relationship between the length (L) and radius (r) of an ideal transition curve is given by 

Test: Highway Geometric Design - 3 - Question 3

Width Of carriage way for a single lane is recommended to be

Test: Highway Geometric Design - 3 - Question 4

Stopping sight distance is the minimum distance available on a highway which is the

Test: Highway Geometric Design - 3 - Question 5

The design value of lateral friction coefficient on highway is

Test: Highway Geometric Design - 3 - Question 6

Camber on highway pavement is provided to take care of

Test: Highway Geometric Design - 3 - Question 7

In the limiting case of overturning while traversing a simple circular curve by a vehicle, pressure below

Detailed Solution for Test: Highway Geometric Design - 3 - Question 7

If the pavement is kept horizontal across the alignment, the pressure on the outer wheels will be higher due to the centrifugal force acting outwards and hence the reaction RB at the outer wheel would be higher. When the limiting equilibrium condition for overturning occurs the pressure at the inner wheels becomes equal to zero and pressure at outer wheels will be maximum.

Test: Highway Geometric Design - 3 - Question 8

The tandwidth required across the alignment of road is

Detailed Solution for Test: Highway Geometric Design - 3 - Question 8

Right of way is the area of land acquired for the road, along its alignment. The width of this acquired land is known as land width and it depends on the importance of the road and possible future development.

Test: Highway Geometric Design - 3 - Question 9

Road alignment is influenced by

Detailed Solution for Test: Highway Geometric Design - 3 - Question 9

Factors which govern the alignment of road are,
1. Obligatory points: These are points either the road alignment has to pass or. not have to pass. '
2. Traffic: The new road to be aligned should keep in view the desired lines, traffic flow patterns and future trends.
3. Geometric Design.
4. Economy.
5. Stability of hill-drainage and geometric standard of hili roads.

Test: Highway Geometric Design - 3 - Question 10

Parabolic camber is preferred for

Detailed Solution for Test: Highway Geometric Design - 3 - Question 10

The camber is given a parabolic elliptic or straight line shape in the cross section parabolic or elliptic shape is given so that the profile is flat at the middle and steeper towards the edges, which is preferred by fast moving vehicles as the have to frequently cross the crown line during overtaking  operation on a two lane highway.

Test: Highway Geometric Design - 3 - Question 11

Stopping sight distance on a national highway at a descending gradient of 2% is

Detailed Solution for Test: Highway Geometric Design - 3 - Question 11

Desigmsffeed on national highway, 
V = 80 km/hr
SSD = vt+ 

Test: Highway Geometric Design - 3 - Question 12

Which one of the following pairs is correctly matched? (Notations have their usual meaning)

Detailed Solution for Test: Highway Geometric Design - 3 - Question 12


Test: Highway Geometric Design - 3 - Question 13

A road camber given in the following figure:

For designing this camber the equation to be used is

Test: Highway Geometric Design - 3 - Question 14

The compensated gradient provided at the curve of radius 60 m with a ruling gradient of 6 percent is:

Detailed Solution for Test: Highway Geometric Design - 3 - Question 14


Test: Highway Geometric Design - 3 - Question 15

if N is the algebraic difference of grades, S is the headlight sight distance in metres, then the transmission length of a valley curve (following standard codes) should roughly be equal to

Detailed Solution for Test: Highway Geometric Design - 3 - Question 15

The head light sight distance should be at least equal to SSD. If the vehicles are overtaking then length curve should be:

Test: Highway Geometric Design - 3 - Question 16

The design speed of a highway is 80 km per hour. Assuming other data as per IRC recommendations, which one of the following is the approximate adopted lag distance?

Detailed Solution for Test: Highway Geometric Design - 3 - Question 16

Lag distance = 0. 278 Vt
Reaction time t = 2.5 sec
Lag distance = 55.6 m

Test: Highway Geometric Design - 3 - Question 17

Consider the following steps involved in the design of super elevation in practice as recommended by IRC :
1. Calculation of the allowable speed for maximum ‘e’ and design value of T
2. Calculation of the super elevation for 75% of the design speed
3. Calculation of the value of ‘e’ and recheck
4. Calculation of the value of ‘f and recheck
The correct sequence of these steps is

Detailed Solution for Test: Highway Geometric Design - 3 - Question 17

2 - 3 - 4 - 1
The step given in 1 is an alternative of step given in 4.

Test: Highway Geometric Design - 3 - Question 18

In highway geometric design, cumulative speed distribution is drawn and the design in checked at which and the design in checked at which percentile?

Detailed Solution for Test: Highway Geometric Design - 3 - Question 18

85th percentile speed is upper limit of speed for regulation and 15th percentile speed is lower limit of speed for regulation.
The 98th percentile speed is the design speed,
