Question 1

As per IRC: 67–2001, a traffic sign indicating the Speed Limit on a road should be of

Question 2

A conventional flow duration curve is a plot between

Question 3

The shape of the STOP sign according to IRC:67–2001 is

Question 4

Which of the following statements CANNOT be used to describe free flow speed (uf) of a traffic stream?

Question 5

If the jam density is given as kj and the free flow speed is given as uf, the maximum flow for a linear traffic speed–density model is given by which of the following options?

Question 6

Two major roads with two lanes each are crossing in an urban area to form an un–controlled intersection. The number of conflict points when both road are one–way is “X” and when both roads are two–way is “Y”. The ratio of X to Y is

Question 7

A two–lane urban road with one–way traffic has a maximum capcity of 1800 vehicles/hour. Under the jam condition, the average length occupied by the vehicles is 5.0 m. The speed versus density relationship is linear. For a traffic volume of 1000 vehicles/hour, the density (in vehicles/km) is

Question 8

On a specific highway, the speed–density relationship follows the Greenberg’s model where are the free flow speed and jam density respectively. When the highway is operating at capacity, the density obtained as per this model is

Question 9

A vehicle moving at 60 kmph on an ascending gradient of a highway has to come to stop position to avoid collision with a stationary object. The ratio of lag to brake distance is 6:5. Considering total reaction time of the driver as 2.5 seconds and the coefficient of longitudinal friction as 0.36, the value of ascending gradient (%) is

Question 10

A Bench Mark (BM) with Reduced Level (RL) = 155.305 m has been established at the floor of a room. It is required to find out the RL of the underside of the roof (R) of the room using Spirit Leveling. The Back Sight (BS) to the BM has been observed as 1.500 m whereas the Fore Sight (FS) to R has been observed as 0.575 m (Staff held inverted). The RL (m) of R will be
