4		BVC Station	77760								Raduis	1000.000
5		BVC Elevation	1279.000								width of carrirage way (G)	7.300	Data input
6		i1 (grade 1)	-0.417%	Data input							Speed km/h	80.000
7		i2 (grade 2)	0.371%
8		Length of	80								Speed m/second	22.222

10		Y1	-0.315		Station	Elevation	Elevation	Elevation			Slope / meter	0.05033916009
11		K	-0.00004921875		10+000	900.000	901.500	903.000			slope %	5.034
12		Station	Design level								Raduis	500.000
13	BVC	77760	1279.000	BVC		G1 1.0%				y1	width of carriage way (G)	7.300
14		77780	1278.936						G2 -1.5 %	y1	Slope / meter	0.101
15		77800	1278.912			LVC= 300				899.25
16		77820	1278.927								Speed / m / second	22.222
17		77840	1278.982				x = distance from BVC to required station
18		77860	1279.075				k = y1 / LVC 2				Speed km / h	80.000
19		77880	1279.209				shift = x 2 * k
20		77900	1279.381				elevation = grade level - shift
21		77920	1279.593
22		77940	1279.845				BVC station = 10+000
23		77960	1280.135				BVC level = 900.000
