In geometric design of roads height of sight distance of a driven is taken as above road surface

For finding stopping distance of a vehicle, the height of line of sight of driver and height of line of obstacle on road are taken as_____respectively.

The stopping sight distance in metres for Indian highways for upward slope i is

where v = speed in kmph
t = time of perception and response
f= coefficient of friction

When a vehicle weighing W traces a horizontal curve of radius R with uniform velocity v it is
subjected to a centrifugal force

When a vehicle traces a horizontal curve, it is subjected to centrifugal force in direction.

A vehicle weighs 50 kN when empty. Its minimum velocity for skidding on a curve is v. If it is weighing 100 kN so that centroid remains at the same height when loaded, it; minimum velocity for skidding on a curve is
