Calculate the minimum and the maximum length of the overtaking zone when the overtaking sight distance is 460 m?

Reaction time of driver increases with

The absolute minimum radius for a horizontal curve designed for a speed of 100 kmph given that the permissible value of super elevation is 0.08 and coefficient of friction is 0.12 will be:

What is the super-elevation for a horizontal highway curve of radius 500 m and speed 100 kmph in mixed traffic condition?

For circular curve of radius 196.20 m, the coefficient of lateral friction is 0.15 and the design speed is 70 kmph. The equilibrium super elevation (for the equal pressure on the inner and outer wheel) would be (take 70 kmph = 19.62 m/sec) (Assume plain and rolling ground)

A transition curve of 120 m long is to be used to join the ends of a circular curve within the straight and circular curve.If the shift of the transition curve is 0.925 m,then calculate the offset(cm) at 40m start of transition curve.

Length of transition curve is 240m and radius of circular curve is 600 m.Find the shift of the curve.

The type of curve which fulfils the condition for an ideal transition curve is

A vertical curve has an up gradient of +1.45% which is followed by a down gradient of -1.35%. The rate of change of curve is 0.35% per chain length of 20 m. What is the length of vertical curve?
