Q1.A crest vertical curve joins two gradients of + 3% and - %2 for a design speed of
80 km/h and the corresponding stopping sight distance of 120 m. The height of
driver’s eye and the object above the road surface are 1.20 m 0.15 m respectively.
The curve length (which is less than stopping sight distance) to be provided is

Q2.On a specific highway, the speed-density relationship follows the Greenbegs
model [V = vf loge (kjk)], where vf and kj are the free flew speed and jam density
respectively. When the highway is operating at capacity, the density obtained as
per this model is
