Guidelines for Geometric Design of Very Low-Volume

Guidelines for Geometric Design of Very Low-Volume Local Roads (ADT=400) addresses the unique design issues highway designers and engineers face when determining appropriate cost-effective geometric design policies for very low-volume local roads. This approach covers both new and existing construction projects. Because geometric design guidance for very low-volume local roads differs from the policies applied to high-volume roads, these guidelines may be used in lieu of A Policy on Geometric Design of Highways and Streets, also known as “The Green Book.” Design values are presented in both metric and U.S. customary units.
