Question: Problem 4 . Design a horizontal curve on a level, two - lane highway ( lane width is 1 2 f t ) . Central

Problem 4. Design a horizontal curve on a level, two-lane highway (lane width is 12ft). Central angle is 14 degrees. Radius is 2,100 ft. Design speed is 80mph. What distance must be cleared from the inside edge of the inside lane? In class, we found the practical value using the shortexplain why in practice engineers always use short-hand equation even when SSD is longer than L.
