2019 Guidelines for Geometric Design of Low Volume Roads 2nd Edition

First published in 2001, AASHTO’s guidelines aim to help highway engineers select appropriate geometric designs for local and collector roads with low daily traffic volumes. AASHTO said the first edition of its low-volume guidelines addressed the design needs of roads carrying average daily traffic volumes of 400 vehicles per day or less. The new second edition of its low-volume road guidance not only replaces the first edition but also includes design advice for local and minor collector roads carrying average daily traffic volumes of 2,000 vehicles per day or less, the organization said. AASHTO added that its low-volume roads geometric design guidelines can be used in lieu of applicable policies presented in its broader “A Policy on Geometric Design of Highways and Streets” handbook, commonly known as the “Green Book.” Guidelines For Geometric Design Of Low-volume Roads, Second Edition Addresses The Unique Design Issues Highway Designers And Engineers Face When Determining Appropriate Cost-effective Geometric Design Policies For Low-volume Local Roads. This Approach Covers Both New And Existing Construction Projects. This Edition Covers New Information Not Yet Released In The Previous Edition. -- Publisher Description.
