Question 6 a) With regards to the relationship between the sight distance and the length curve as established in Figure 2, determine the minimum length of the curve if the hazard is assumed to be at a height from the road surface equal to the eye height of the driver. Note that the driver's eye height is an average height and the algebraic difference in grades is in decimal form.
