The sight distance of a sag parabolic curve is 116.85 m. long with grade tangents of -1.98% and +2.58% respectively. (a) Compute the length of the parabolic curve in m. (b) Compute the maximum velocity of car that can maneuver on the curve to avoid possible collision of any approaching cars in kPh and (c) determine the perception-reaction time of the driver to avoid collision in seconds. Assume coefficient of friction between tires and pavement to be 0.35.
