Ahorizontal curve on a two-lane highway (11ft lanes) has a central angle of 33 degrees and designed for 60 mi/h with an 8% superelevation. a). if the pi is at station 300+00, what is the station of the pt and how many feet have to be cleared from the inside lanes shoulder edge to provide adequate stopping distance? b). if the normal component of the centripetal force was considered, how much shorter would the radius of the curve be?
