200-6 Highway Design Manual July 1, 2020 Figure 201.4 Stopping Sight Distance on Crest Vertical Curves Drivers eye height is 3 ½ feet. Object height is ½-foot. L = Curve Length (feet) A = Algebraic Grade Difference (%) S = Sight Distance (feet) V = Design Speed for “S” in mph K = Distance in feet required to achieve a 1% change in grade. K value as shown on graph is valid when S <> L L = 2S – 1329/A When S <><> L L = 2S - (400 + 3.5S)/A When S <>
