A reverse curve connects two converging tangents intersecting at an angle of 30 degrees. The distance of this intersection from the PI of the curve is 150 meters. The deflection angle of the common tangent from the back tangent is 20 degrees (first curve) and the azimuth of the common tangent is 320 degrees. The degree of curve of the second simple curve is 6 degrees and the stationing of the point of intersection of the first curve is 4+450. Determine the stationing of the PC, PRC, and PT. Use the formula R=1145.916/D

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.
