GATE CE 2022:Transportation Engineering & Surveying - Subject Revision Quiz for ESE & GATE CE Exams

Question 1

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 2

A three–phase traffic signal at an intersection is designed for flows shown in the figure below. There are six groups of flows identified by the numbers I through 6. Among these 1, 3, 4, and 6 are through flows and, 2 and 5 are right turning. Which phasing scheme is not feasible?

Question 3

The design speed for a two–lane road is 80 kmph. When a design vehicle with a wheel base of 6.6 m is negotiating a horizontal curve on that road, the off–tracking is measured as 0.096 m. The required widening of carriageway of the two–lane road on the curve is approximately

Question 4

Consider the following statements in the context of geometric design of roads
I: A simple parabolic curve is an acceptable shape for summit curves
II: Comfort to passengers is an important consideration in the design of summit curves
The correct option evaluating the above statements and their relationship is

Question 5

The following data are related to a horizontal curved portion of a two–lane highway : length of curve = 200 m, radius of curve – 300 m and width of pavement = 7.5 m. In order to provide a stopping sight distance (SSD) of 80 m, the set back distance (in m) required from the centre line of the inner lane of the pavement is

Question 6

If the total number of commercial vehicles per day ranges from 3000 to 6000, the minimum percentage of commercial traffic to be surveyed for axle load is

Question 7

A box sextant has the main scale readings in 10' graduations. If the least count desired for an extended vernier is 10", then 'M' spaces of the main scale should be equal to 'N' spaces of the vernier scale. The value of M and N are respectively.

Question 8

A 20 m chain was found to be 20 cm too long after chaining a distance of 2500 m. It was found to be 28 cm too long at the end of the day’s work after chaining a total distance of 4000 m. What is the true distance (in m, correct to one decimal digit) if the chain was correct before the commencement of the day’s work?

Question 9

A person standing at the top of a 10m high embankment on a port can just see the bow of a ship leaving the port. She then climbs a tower of height 50m and observes that she can again see just the bow of the ship. If it takes her 30 minutes to climb up the tower, find out the speed of the ship in kmph.

Question 10

The scale of an aerial photograph is 1 cm = 150 m and the size of the photograph is 20cm X20cm. Determine the number of photograph in each strip to cover an area of 15kmX15 km if the longitudinal overlap is 70% and side overlap 30%.

Question 11

Following data is about a reservoir near Jiya Sarai, Delhi.

Depth of water level from ground, when the reservoir is 60% full, is _________m.
[Assume volume between two consecutive contours

Question 12

If the departure and latitude of a line are +78.0m and – 135.1m respectively, the whole circle bearing of the line is

Question 13

A close traverse has following length and bearing:

Calculate the length of CD in meter

Question 14

Assertion (A): Plane table survey might be preferred over theodolite survey for small scale maps.

Reason (R): Plane table survey can be used in areas with magnetic attraction as well.

Question 15

An area was traversed using a theodolite and an electronic distance measurement instrument (EDMI). If the least count of theodolite is 20”. What will be the degree of precision required for linear measurement.

Assume. tan (20’’) = 9.696 × 10^–5
