The essential design controls and geometric design and aesthetic standards for primary access, circulation local, and sublocal roads were developed from a 2-year study which included a review of the state of the art, the development of a functional classification scheme, design vehicles and design speeds, geometric standards for alignment, sight distance, and cross-section elements, the review of roadway aesthetic design criteria, and an examination of future recreational roads. Standards are given for minimum stopping, passing and lateral sight distance; horizontal alignment (maximum superelevation, maximum curvature, superelevation runoff and curve widening); vertical alignment; and cross section elements. Immediate activities for immediate implementation, and long range activities for continuing recreation al planning are outlined.
