A particular crest vertical curve has long been criticized as being unsafe. Its length is 400 ft. The prevailing speed on the crest vertical curve is 50 mph. In its present condition, its tangent grades are +2% and -3%. Does this curve meet minimum SSD according to the AASHTO. If it is possible to enforce a speed limit of 45 mph on the curve, will the vertical curve meet minimum SSD standards?
