A vehicle is traveling at 60 mph on a level two-lane road with a horizontal curvewith a radius of 1000feet. The pavement has a wet coefficient of friction of 0.30. Each lane is 12 feet wide and there is an 8foot shoulder on both sides of the road. Calculate the minimum distance that should be cleared from the edge of the shoulder if the central angle of the curve equals 35.76 degrees for the vehicle to safely stop in an emergency situation. Use the AASHTOdesign values for stopping sight distance.
