Q$2//$ Predict the departure sight distance for single unit truck vehicle travels $(5$ m length$)$ at design speed of $\backslash (40\backslash$mathrm$\{$~km$\}/\backslash$mathrm$\{$h$\}\backslash )$ in signalized urban T$-$intersection of two way six lanes $(3$ m width$)$ and $\backslash (5\backslash \%\backslash )$ grade, if the right turns on a red signal are to be permitted from any approach. Compare this results with that obtained when yield sign considered as the control case. $($Note: the perpendicular road may represents the minor road$)$
