Provide illustration and complete solution.
A reverse curve with diverging tangent is to be designed for a proposed highway as illustrated below. The reverse curve is composed of one compound curve, from point A to C, and one simple curve, from point C to D. Point A is located at the Point of Curvature having Station 12+808.35, point B is located at the Point of Compound Curve, point C is located at the Point of Tangency. The back tangent of the reverse curve is having an located at the Point of Reverse Curve, and point D azimuth of 388.5 degrees and the forward tangent is having an azimuth of 748.8 degrees. The common tangent for the reverse curve has an azimuth of 313.1 degrees from south. It has been found out that the long chord of curve A to C is thrice the value of the chord in curve C to D. The common tangent of the curve A to C is having an azimuth of 254.1 degrees from south and the chord of curve C to D is 161.3m long.
