abstract="The results of studies of accidents and roadway geometrics on two-lane rural highways are presented. The studies were a portion of federally sponsored research on the safety and operations of highway curves. A data base was assembled from geometry files of four states. Two sets of analyses were performed: (a) a multivariate analysis of the incremental accident effects of five basic geometric and traffic variables, and (b) a detailed study of the geometric and environmental characteristics of site populations with high- and low-accident rates. The study findings demonstrated that degree of curve, extent of roadside hazard, and pavement surface quality (i.e., available friction) have the greatest impact on safety of two-lane rural highway curves. Other notable effects were obserued with shoulder width, roadway width and length of curve. The results of studies of accidents and roadway geonetrics on two-lane rural highways, perforned as a part of FHWA-sponsored researchr are presented in this paper. Two separate accidlent analyses were undertaken: analysis of covariance was used to study the increnental accident effects of basic geornetric and traffic variables, and discrirninant analysis was applied to a detailed study of the geonetry of sites that had either very high or very low accident rates.<p /><p>Language: en</p>",
