Situation $4$:

A six$-$lane two way highway is to be designed according to the standards set by the DPWH for desirable radius and stopping sight distance. Expected average daily traffic is $1532$ vehicles per day.

Flat surrounding topography

Lane width $=4\mathrm{.}0m$

Design speed is $100kph$

Grade is$.-1\mathrm{.}4\%$

Determine the ff:

$28.$ Superelevation and the height of the superelevation

$29.$ Length of curve widening if the wheelbase is $2\mathrm{.}98m$ long

$30.$ Distance that must be cleared from the inside edge of the inside lane to provide sufficient sight distance
