Example #8: Designing a Sag Vertical Curve

Example #8: Designing a Sag Vertical Curve. Design a length of vertical curve for a sag curve based on Comfort Ride Headlight Sight Distance Design Speed = 40 mph SSD = 305 g1 = -3.2% g2 = +2.4%. Solution: Determine the change in grade elevation A = |g2-g1| = |2.40-(-3.2)| A = 5.6 %.
