Research for AASHTO Standing Committee on Highways. Task 343. An Update to AASHTO's Guidelines for Geometric Design of Very Low-Volume Local Roads

The objective of this project is to identify needed updates to current design policy, and/or necessary changes in the fundamental design process to incorporate the latest design principles. The geometric design of facilities designated as low volume presents unique challenges to engineers across the United States. These roadways, designated by low traffic volumes thus reduced frequency of crashes, require the use of design principles unlike those applied to higher volume roads. Accomplishing the design of a low-volume highway - its three-dimensional features (horizontal alignment, vertical alignment and cross-section) and appurtenances to provide for drainage, traffic control and safety, requires a well-defined process. the American Association of State Highway and Transportation Officials (AASHTO) initially developed the guidelines for geometric design of very low-volume roads in 1996 and the final product was published in 2001. During the past 11 years, much has changed in the vehicle fleet, knowledge about driver characteristics (i.e., human factors), and safety and operations of these types of facilities. AASHTO policy requires that all reference material be reviewed and analyzed for potential updates. An assessment of the current publication and design process is needed to appropriately leverage and/or reflect recent advances and emerging issues contained in the documents.
