1 / 10

The centrifugal ratio of a vehicle is 0.25, width of vehicle is 2.4 m, height of vehicle to its CG is 4.2 m, lateral friction is 0.15, assuming no super-elevation, then

2 / 10

Consider following factors:
I. Length of the vehicle
II. Width of the vehicle
III. Approach speed
IV. Stopping time for approaching vehicle
V. Passing sight distance
Which of these factors are taken into consideration for determing yellow time of traffic signal at intersection?

3 / 10

A summit curve is formed at the intersection of 3% upgrade and 5% downgrade. What is the length of the summit curve in order to provide a stopping distance of 128 m is

4 / 10

What will be the non passing sight distance on a highway for a design speed of 100 km/h when its ascending gradient is 2%. Assuming coefficient of friction as 0.7 and brake efficiency is 50%.

5 / 10

A circular curve of radius 300 m, coefficient of lateral friction of 0.15 and the design speed is 40 km/h. The
super-elevation at which equal pressure is distributed on inner and outer wheel would be

6 / 10

A summit curve is to be designed with two gradients +2% and –6%. The rate of change of gradient is 1% per 100 m length. The minimum radius of curve is

7 / 10

The design speed of a road is 40 km/h and the radius of curve is 200 m. Then find the length of transition curve for the road of plain and rolling terrain

8 / 10

If width of the vehicle is 6 m and height of the vehicle is 10 m and coefficient of friction 0.15, then

9 / 10

The turning angle of the curve is 30° and tractive force on the vehicle is 300 N. Then the loss of tractive force due to turning of vehicle in horizontal curve is

10 / 10
