While aligning a hill road with a ruling gradient of 6%, a horizontal curve of radius 50 m is encountered. The grade compensation (in percentage up two equal places) to be provided for this case would be _______

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:

The VPI (vertical point of intersection) is 100 m away (when measured along the horizontal) from the VPC (vertical point of curvature). If the vertical curve is parabolic the length of the curve (in meters and measured along the horizontal) is ________

A circular curve of radius R connects two straights with a deflection angle of 60°. The tangent length is

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:

In a one-lane one-way homogeneous traffic stream, the observed average headway is 3.0 s. The flow (expressed in vehicles/hr) in this traffic stream is________

A two-lane, one-way road with a radius of 50 m is predominantly carrying lorries with a wheelbase of 5 m. The speed of lorries is restricted to be between 60 kmph and 80 kmph. The mechanical widening and psychological widening required at 60 kmph are designated as w_me,₆₀ and w_ps,₆₀, respectively. The mechanical widening and psychological widening required at 80 kmph are designated as w_me,₈₀ and w_ps,80, respectively. The correct values of w_me,60, w_ps,60, w_me,80, w_ps,80, respectively are
