Low-Volume Roads and Road Safety Audits

Transportation Research Record: Journal of the Transportation Research Board, 2011
Low-volume roads, paved and unpaved, pose a safety concern for various road users. Changes in roadway ownership, diverse user groups, traffic patterns, and new developments often create conditions unanticipated in the original roadway design. This problem is particularly true for low-volume roads, many of which were not formally designed.

Low-Volume-Road Lessons Learned

Transportation Research Record: Journal of the Transportation Research Board, 2007
The Minnesota Department of Transportation built the Minnesota Road Research Project (MnROAD) and its low-volume road (LVR) between 1990 and 1993. The 2.5-mi LVR consists of a two-lane roadway that originally contained gravel, hot-mix asphalt, and concrete test sections designed for low-volume road research.

Financing Low-Volume Road Improvements

Transportation Research Record: Journal of the Transportation Research Board, 2011
Over the past 30 years the population of Washington County, Oregon, has doubled to more than 530,000 residents. With growth limited to the urban area, resources for urban roads mostly kept pace with population growth, but little funding was available for maintenance and improvement of rural local roads.

Low-Volume Road Bridge Alternative

Transportation Research Record: Journal of the Transportation Research Board, 2000
Recent reports indicate that a significant number of the nation’s bridges are either structurally deficient or functionally obsolete. A large number of these bridges are on the secondary road system and fall under the jurisdiction of county engineers with limited budgets and engineering staff.
