What is Horizontal Curve Design Calculations about?
This document provides an example problem calculating the required superelevation and minimum tangent length between two horizontal curves on an exit ramp. For curve 1, the required superelevation is 6.0% for a 50 mph design speed on a 1,790 ft radius single lane curve. For curve 2, the required superelevation is 9.0% for a 35 mph, 440 ft radius two lane curve. The minimum tangent length between the curves needed to minimize lateral motion is calculated to be 408.8 feet.
