This report presents guidance for roadway geometric designers on how best to accommodate large trucks on the U.S. highway system. Under National Cooperative Highway Research Program (NCHRP) Project 15-21, a research team reviewed the range of dimensions and performance characteristics of trucks currently used on U.S. highways and predicted how these characteristics may change in response to current political, economic, and technological trends. The research team conducted an analysis of those geometric design features affected by vehicle characteristics and then evaluated the adequacy of current geometric design policy to accommodate the current and anticipated truck fleet. Based on the findings, the report makes recommendations for a number of changes to the American Association of State Highway and Transportation Officials (AASHTO) "Policy on Geometric Design of Highways and Streets" ("Green Book"). The report (1) provides valuable guidance for designers of roads and facilities that need to accommodate large trucks and (2) will assist AASHTO in updating geometric design policy. The information developed in this project will also be useful as input to future editions of other documents such as the Transportation Research Board (TRB) "Highway Capacity Manual," the Federal Highway Administration (FHWA) "Manual on Uniform Traffic Control Devices," and the AASHTO "Roadside Design Guide."
