Determine the minimum length (in ft) of a sag vertical curve if the grades are −6 percent and +3 percent. design speed is 60 mi/h. consider the following criteria—stopping sight distance, comfort, and general appearance. (assume the perception-reaction time is 2.5 seconds, deceleration rate is 11.2 ft/s2, and the sight distance is less than the length of the curve.)
