A horizontal curve has two lanes per direction. The radius, measured to the center marking that separates the two opposing directions is 700 ft. The lane width is 14 ft. The wall of the tunnel is 10 ft from the right edge of the right travel lane. Calculate S. If vehicle A traveling at 50 mph on the right lane has just passed the PC, and vehicle B is stopping in the middle of the right lane at PT, can vehicle A stop before colliding with vehicle B? Explain your answer.
