Question 1

A two lane road having free mean speed 80kmph & jam density 40 per lane per km. If the density of road at any time is 30 per lane per km, then average speed of vehicle at this density is according to Green Shield model?

Question 2

The optimum cycle time using Webster method, if total lost time is 6 seconds, normal flow is 500,700,450 and saturation flow rate is 2000veh/hr is ____s?

Question 3

The captain of the ship having an elevation of ‘X’ meters above the see surface gazes the light house of height 42 meters above the sea surface. Determine the elevation of the ship considering the distance between the ship and the dip of horizon as 9.44 km and the distance of the ship from light house as 33.8 km.

Question 4

In a closed traverse, latitudes and departure of the sides were calculated and it was observe that
∑latitude = 1.39, ∑departure = -2.17
Calculate the bearing of the closing error-

Question 5

Following observations were taken during reciprocal levelling. The distance between two stations P & Q is 1125m.

The error due to refraction effect and curvature effect are 0.014m and 0.095m. The true difference in level and the upward error in line of collimation is _____,______

Question 6

An instrument located at a distance of 2500m away focusses the vane attached to a levelling staff at a height of 4.12m. The angle of elevation reads to be 9 °. Considering the reduced level of the telescope trunnion axis as 412.56m, compute the RL of the staff.

Question 7

A closed traverse ABCDE was surveyed and the observation were made as shown in the table below.

The length (in m) of lines BC and DE respectively, are

Question 8

A section line AB 300m long on a flat terrain measures 102.3mm on a vertical photograph. A radio tower also appears on the photograph .The distance measured from the principal points to the image of the bottom and top of the radio tower are found to be 70mm and 80mm respectively . The average elevation of the terrain was 553m , The height of the tower__________ m.

Take f=152.4mm

Question 9

A Marshall specimen is prepared for bituminous concrete with a bitumen content of 4 percent by weight of total mix. The theoretical and the measured unit weights of the mix are 2.386 g/cm³ and 2.25 g/cm³ respectively. The bitumen has specific gravity of 1.1. The percent voids in mineral aggregate filled with bitumen (VFB) are

Question 10

The monthly mean temperature of maximum daily temperature and monthly mean of average daily temperature of the hottest month of year are 52 degree Celsius and 40 degree Celsius respectively. Then airport reference temperature is?

Question 11

Practical capacity(veh/hr) of rotary is_, if width of weaving section is 6m, mean of entry & exit width is 8m, weaving ratio is 0.4 & length is 18m?

Question 12

A pre-timed four phase signal has critical lane flow rate for the first three phases as 230, 195 and 215 veh/hr with saturation flow rate of 2100 veh/hr/lane for all phases. The lost time is given as 4.5 second for each phase. If the cycle length is 75 seconds, the effective green time (in seconds) of the fourth phase is
