Design a summit curve for a national highway for ISD of 180m at the junction of the rising gradient of 2% and a falling gradient of 3%.
1
Length of the summit curve is 168.75 m.
2
Length of the summit curve is 168 m.
3
The position of the crest from VPT(vertical point of tangency) is 67.2 m.
4
The nature of the summit curve is a simple parabola.
