A horizontal curve on a two-lane highway (12 ft lanes) has a PC at station 123+80 and PT as station 129+60. The central angle is 30 degree, the super-elevationis 0.06 and 22 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum sate speed (assuming current design standards) to the nearest 5 mi/h.

A horizontal curve forms part of a four-lane highway that has a posted speed limit of 40 mph. The lane width is 12 ft and the radius of the horizontal curve equals 1000 ft at the highway centerline. Determine the minimum distance a large billboard can be placed from the centerline of the inside lane of the curve, without reducing the required stopping sight distance. (Use default values of reaction time and vehicle deceleration).
