Test: Transportation Engineering- 1

Question 1

A super-elevation e is provided on a circular horizontal curve such that a vehicle can be stopped on the curve without sliding. Assuming a design speed v and maximum coefficient of side friction f_max, which one of the following criteria should be satisfied?

Accepted Answer

e ≤ f_max

Answer

e > fmax

Answer

no limit of e can be set

Answer

Question 2

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

Accepted Answer

u_f is the speed at which flow is maximum and density is optimum.

Answer

u_f is the speed when the flow is negligible.

Answer

u_f is the speed when density is negligible.

Answer

u_f is affected by geometry and surface conditions of the road.

Question 3

The safety within a roundabout and the efficiency of a roundabout can be increased respectively by

decreasing the entry radius and increasing the exit radius.

Answer

increasing the entry radius and increasing the exit radius.

Answer

increasing the entry radius and decreasing the exit radius.

Answer

decreasing the entry radius and decreasing the exit radius.

Question 8

On a circular curve, the rate of super-elevation is e. While negotiating the curve a vehicle comes to a stop. It is seen that the stopped vehicle does not slide inwards (in the radial direction). The coefficient of side friction is f. Which of the following is true:

Accepted Answer

e &le; f

Answer

f < e < 2f

Answer

e &ge; 2f

Answer

None of the above
