Highway design includes designing alignments. Please answer the following questions:

A horizontal curve connects the tangents of a two$-$lane highway that has a posted speed limit of

$80k\frac{m}{h}$ and a $3\%$ upgrade slope $($inside lane$).$ The curve is design on minimum radius. If the

highway curve is superelevated, $e=6\%,$ determine the horizontal sightline offset $($HSO$)$ that

a large billboard can be placed from the centerline of the inside lane of the curve, without reducing

the required SSD$.$ Perception$-$reaction time is $2\mathrm{.}5sec,$ and $f=0\mathrm{.}35.$

An exclusive right$-$of$-$way of bicycle two$-$lanes is to be designed. Select proper design

facilities based on what you have been taught. Tip: width, grade, speed, radius, and SSD$.$

How many conflict points $($diverging$,$ merging, crossing$)$ on at grade T$-$intersection?

The edge of travelway turning radius of an intersection angle is $120$ and $SU-9($SU$-30)$ vehicle

design is $...$

What are the factors that influence the design of the edge of pavement?
