This document provides guidelines for the geometric design of rural roads with very low traffic volumes, specifically those with an annual average daily traffic of 400 or less. It addresses various aspects of road design, including alignment, cross-section, sight distance, and pavement characteristics. The guidelines are intended to assist transportation agencies in developing safe and efficient roadways that meet the needs of low-volume traffic while considering environmental, economic, and safety factors. The document includes updates and modifications to previous versions, ensuring that the information remains relevant and applicable to current design practices. It covers key design elements such as horizontal and vertical alignment, intersection design, drainage, and signing. The content is structured to facilitate easy reference and application by engineers and planners involved in the design and maintenance of rural road networks.
