摘要: This report evaluates and recommends revisions to the horizontal curve guidance presented in the 1994 American Association of State Highway and Transportation Officials (AASHTO) publication, "A Policy on Geometric Design of Highways and Streets." The two principal design elements evaluated were the use of superelevation and the transition from a tangent to a curve, though all elements of a curve were considered in the analysis. Geometric designers will gain a greater understanding of the physics involved in negotiating a curve and the procedures for designing them by reading this report.
