If a horizontal curve in an urban area to be constructed to meet the minimum AASHTO criteria for design at a design speed of 45 miles per hour, on a three percent downgrade; to what distance away from the edge of pavement would all sight obstructions need to be kept clear to maintain adequate stopping sight distance for design? (Helpful information Assume worn tire tread, a wet road surface, and a side friction factor of 0.13) If a horizontal curve in an urban area to be constructed to meet the minimum AASHTO criteria for design at a design speed of 45 miles per hour, on a three percent downgrade; to what distance away from the edge of pavement would all sight obstructions need to be kept clear to maintain adequate stopping sight distance for design?
