The AASHTO Green Book criteria for intersection sight distance are felt to very conservative. They are often viewed as providing desirable sight distances for conditions, rather than the minimum acceptable. The models describing intersection operations on which the

Refer to the AASHTO Green Book Chapter 3, Elements of Design, when determining the radii of horizontal curves and corresponding superelevation (if applicable). Wherever possible, minimum curve radii and maximum superelevation rates should be avoided for any given speed design.
