For a simple$-$circular highway curve, the design speed is $100k\frac{m}{h}r$ and the

superelevation rate that will be used is $8\%.$ The roadway has a width of per

direction$)$ and $2\%$ normal crown. The point of intersection is at $57+34\mathrm{.}23m.$

Superelevation will be introduced by rotation about the centerline and the

superelevation runoff length will be split $2$:$1$ between the tangent and the curve. The

angle of intersection is $49{52}^{\text{'}}$ and the radius that will be used is $1\mathrm{.}2$ times the minimum

allowable and rounded$-$up to a multiple of $5m.$ Find the stationing of the PC and PT and

the stationing of the start and end of the tangent runout and superelevation runoff

segments for introducing and removing superelevation.
