A curved highway has only one lane with a centerline radius of
800 ft. A building is located
25 ft. from the centerline. The road is level. Take the coefficient of braking friction as 0.36
and perception-reaction time as 2.5 seconds.
a. Determine the appropriate speed limit on the curve to ensure stopping sight distance;
b. Determine the rate of super-elevation (assume the coefficient of side friction equals
