A curve of radius 300 ft and e = 10% is located at the section of an existing rural highway, which restricts the safe speed at this section of the highway to 40% of the design speed.This reduction caused a high accident rate at this section.To reduce the crash rate, a new alignment is to be designed with horizontal curve.Determine the minimum radius of the new curve if the safe speed should be increased to the design speed.Use fs = 0.17 for the existing curve.Use e = 10% for the new curve.
