The design speed of a multilane highway is 60 mi/h. What is the minimum stopping sight distance that should be provided on the road if (a) the road is level and (b) the road has a maximum grade of 4%? Assume the perception-reaction time = 2.5 sec.
Calculate the minimum length of overtaking
zone of a one way traffic road if the velocity
of the overtaking and the overtaken vehicles
are 110 and 60 kph, and the acceleration of
the vehicle is 1.2 m/s^2. (Hint: overtaking
sight distance is just a third of minimum
length of overtaking zone).
