QUESTION 1 The grades given for a vertical curve on a roadway are as follows: Back tangent gradient = 4 % Forward tangent gradient =-4 % 1. Determine the minimum required length of the vertical curve. 2. Compute the maximum safe speed on this curve if the braking deceleration rate is equal to 3 m/s2.
