A horizontal curve is designed for a four-lane highway (lane width=10ft.). The central angel is 40 degrees. The PI
point is at 2600+00 and the tangent distance is equal to 520ft. The side friction factor is 0.08 and superelevation is
9%. What is the stationing of PC and PT? and what is the safe vehicle speed?
