Highway design includes designing cross sections and alignments. Please answer the

following questions:

A crest vertical curve joining $a+2\mathrm{.}5$ percent and $a-2\mathrm{.}5$ percent grade is to be designed for $110$

$k\frac{m}{h}.$ If the tangents intersect at station $(1+250)$ at an elevation of $76\mathrm{.}2m.$

Determine the stations and elevations of the BVC and EVC.

Calculate the elevations of Sta. $1+150.$ Tip. Use K factors.

A sag vertical curve joining $a-2\mathrm{.}5$ percent and $a+2\mathrm{.}5$ percent grade is to be designed for $110$

$k\frac{m}{h}.$ If the tangents intersect at station $(1+250)$ at an elevation of $76\mathrm{.}2m,$ determine the

stations and elevations of the BVC and EVC. Tip. Use $K$ factors.

What is the distance over which the pavement cross slope $(2\%)$ on the outside lane changes

from zero $($flat$)$ to full superelevation of the curve $(8\%)?$ The segment is two lane highway. The

designed speed is $60kph.$ Use equations not tables.

The edge of travel way turning radius of an intersection angle is $60$ and SU$-9($SU$-30)$ vehicle

design is $...$

What is the minimum width of divisional island serving pedestrians?
