• Abstract:
  The procedures described in this handbook are intended to improve consistency in curve signing and driver compliance with the advisory speed. The handbook describes guidelines for determining when an advisory speed is needed, criteria for identifying the appropriate advisory speed, an engineering study method for determining the advisory speed, and guidelines for selecting other curve-related traffic control devices. The handbook is intended for use by traffic engineers and technicians who have been given the responsible charge of evaluating and maintaining horizontal curve signing and delineation devices. The procedures described in this handbook are applicable to rural highways. However, they may be useful for establishing advisory speeds for urban streets. The curve advisory speed and other curve-related traffic control devices should be checked periodically to ensure that they are appropriate for the prevailing conditions. Changes in the regulatory speed limit, curve geometry, or crash history may justify the conduct of an engineering study to re-evaluate the appropriateness of the existing signs and the need for additional signs.
