Highway curve design manual

This page states that the criteria contained in this Roadway Design Manual are applicable to all classes of highways from freeways to two-lane roads. This page gives a brief description of each section by roadway classification. The page also discusses how the manual is formatted and gives a listing of external reference documents. The primary functions of the Highway Design Manual (HDM) are to: (1) provide design criteria, requirements, and guidance on highway design methods and policies which are as current as practicable, and (2) assure uniformity in the application of design practices throughout the New York State Department of Transportation consistent with the collective experience of the .  · Highway Design Manual July 1, Stopping Sight Distance on Horizontal Curves Where an object off the pavement such as a bridge pier, building, cut slope, or natural growth restricts sight distance, the minimum radius of curvature is determined by the stopping sight distance.

Issued by Engineering Bulletin Effective with Design Approval on or after September 1, Highway Design Manual July 1, exceed feet and a tangent of at least feet should be provided between the last curve on the ramp and the ramp terminal. Special attention should always be given to exit ramps that end in a hook to ensure that adequate sight distance around the curve, adequate deceleration length prior to the curve.
