If G₁=2 % and G₂=-4%, the required vertical curve is a crest curve. O True False QUESTION 5 A vertical curve is needed to join to tangents; G₁-2% and G₂-5%. Assuming the worst case scenario for braking, and the AASHTO recommended values for deceleration and perception-reaction time, calculate the minimum length of curve (ft) needed to satisfy the comfort criteria. The design speed is 50 mph.
