Two tangents intersect at an angle of 42° are to be connected by a reversed curve. The distance of the point of intersection to the point of curvature and point of tangency are 400 m and 50 m, respectively. The azimuth of the forward and the backward tangents are due east and 228°, respectively. The stationing of PC is 10+221.310 and the radius of the first curve is 200 m.

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.
