A horizontal curve along a two-lane highway with 12-ft lanes is designed with a central angle of 29.93 degrees and a superelevation rate of 8 percent. The station of the PC and PI are 100+00.00 and 103+22.36, respectively. Given this information:
a. Determine the design speed of this curve. (12 points)
b. Calculate the distance that must be cleared from the center of the inside lane in order to provide sufficient stopping sight distance (8 points)
