4.2 A 200 m long sag curve is used under a grade separation structure. The curve joins an entry grade of - 3% and exit grade of + 5%. If the required vertical clearance is 5.5 m, determine the available sight distance over the curve. Assume driver eye height and dangerous object height of 1.8 m and 0.15, respectively. If the information available is not complete, please assume and specify a reasonable value and continue with the assignments.
