This document provides geometric design guidelines for very low volume roads. The purpose is to help highway designers select appropriate geometric designs for roads that have very low traffic volumes traveled by motorists who are generally familiar with the roadway and its geometric design. Very low volume roads are defined as: a road that is functionally classified as a local road and has a design average daily traffic volume of 400 vehicles per day or less. The scope of the guidelines includes geometric design for new construction and for improvement of existing roads. Geometric design criteria for new construction apply for construction of a new road where none existed before. Projects on existing roads may involve reconstruction, resurfacing, rehabilitation, restoration, and other types of improvements.
