Sketch a proposed Typical Cross Section for an existing two$-$lane, two$-$way state

highway with an estimated $3650$ AADT on a secondary rural highway road with a

posted speed limit of $100$km$/$h$.$ Show in your sketch the key features you would

recommend in cross sectional layout if an historical crash analysis had shown a

number of cycle crashes had occurred alongside a number of runoff road and one

head on crash in the last $5$ years that had occurred on this road section.

The existing cross section has $3\mathrm{.}3$m traffic lanes with $0\mathrm{.}30$m shoulders on either

side of the road with some deep longitudinal drains and steep side batters along the

curvilinear alignment. Alongside your sketch, briefly discuss the key reasons for

your recommended cross sectional layout.
