| Abstract | The United States has over 4.8 million km (3 million mi) of two-lane highways, and about 90 percent of these roads carry traffic volumes less than 2,000 vehicles per day. Because funding is not available to reconstruct all two-lane highways to meet current design standards of the American Association of State Highway and Transportation Officials (AASHTO), State and local highway agencies must decide which roads to reconstruct. Current design standards do not provide the guidance necessary to make safety, operations, and cost trade-offs. This investigation was undertaken to develop revised roadway width guidelines based on accident analyses, cost estimates, and operational considerations. This study was conducted through a grant from the National Cooperative Highway Research Program (NCHRP). |
