What is the recommended clear zone distance for the following roadway situations? (Use the Clear Zone nomograph to find solutions)
a. ADT = 2,500 vpd Design speed = 60 mph Slope = 5:1 (cut) Degree of curvature = none
b. ADT = 15,000 vpd Design speed = 50 mph Slope = 6:1 (cut) Degree of curvature = 5°
c. ADT = 1,600 vpd Design speed = 40 mph Slope = 4:1 (fill) Degree of curvature = 6°
(For b and c, indicate required clear zone width on outside of curve, and on inside of curve.)
