Two tangents making an angle of 62° from each other is connected by a simple curve. A point “x” on the curve is located by a distance along the tangent from the PC equal to 240 m and an offset from the tangent equal to 60 m. The PC is at station 10+080. Compute for the radius, tangent distance and the stationing of point “x” on the curve.

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.
