Situation 4: A turn around pattern which fits with the topography is provided in a highway by connecting four tangents with a compound curve consisting of three simple curves. The azimuth of AB = 220° 15', BC= 264°30', CD=320°24', and DE=32°58'. The radius of the last curve is four times sharper than the first curve. The distance BC=303 m and CD=200m. 1. 2. Comp. the radius of the 3rd curve Comp. the radius of the second curve 3. If P.C is at 12+152.60, what is the stationing of the P.T.
