I. Using and calculating by Cartesian Coordinates $($lengths$,$ angles, directions, polygonial $\backslash$& true km$\text{'}$s$)$

$1\mathrm{.}1.$ Coordinates of Cardinals $($important stations or points such as A$,$ PCl$,$Pli,PTi, B etc.$)$

IF Rhc$=500$ m$,$ and km A$=0$ then Calculate

d$)$ Tangent Length $($T$)$ and Horizontal Curve Length $($Lhc$)$

e$)$ true $\backslash$& polygonial kilmeters of PC$,$ PI$,$ PT and B$)$

f$)$ Horizontal Curve elements $($E$,$M$,$K$,$D$)$

g$)$ Calculate station at which every $\backslash ($ R $/10\backslash )$ meter intervals along alignment through $\backslash ($ A $\backslash )$ to $\backslash ($ B $\backslash ).$

for Vdesign$=80$ km$/$hr$,2$x$1$ highway $($two way$-$ one lane highway$)$ which has Width of traffic lane$=3\mathrm{.}50$m$,$ Width of shoulder$=2\mathrm{.}50$ m and crown slope $($cross$-$sectional slope or initial slope on tangent$)$ is $(\backslash (-2\backslash \%,-2\backslash \%\backslash ))$ which is $($left e $0,$ right e$0)$

h$)$ Calculate superelevation in percent along the stations at defined above$($g$)$

for longitudinal slope $\backslash (=5\backslash \%\backslash ),$

i$)$ Calculate elevations of Left edge, Centerline and Right Edge along the stations at defined above$($g$)$
