A compound curve that starts at stationing 4+321 consists of 2 simple curves. The 1st curve has a radius of 300 m and an angle of intersection of 45°. The 2nd curve has a radius of 500 m and an angle of intersection of 35°. The common tangent is parallel to the long chord of the compound curve. Compute the stationing of V, V1, V2, PCC and full stations, and the length of the long chord.

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.
