What is the sight distance, $S($i$.$e$.,$ available stopping sight distance$)$ on a horizontal curved section of $2-$lane

road $(11\text{'}$ wide lanes$)$ if the road's centerline radius is $580\mathrm{.}00\text{'}$ and the horizontal sightline offset, HSO $($as

measured from CL of the inside lane$)$ is $40\mathrm{.}00\text{'}?$ Also, based on equation's calculated value, what is the

maximum safe design speed $($to $5mph)$ for this scenario based on stopping sight distance$)?$
