Five quantitative relationships relating some geometric features of two-lane rural highways to accident rates were reported in Special Report 214 of the Transportation Research Board. In this study, three of these models were applied to data from several two-lane sections of two rural highways in the province of British Columbia. The models were used to predict accident rates in the road sections for the five-year period covering 1981 to 1985. The R² values resulting from linear regression analyses of the predicted accident rates on the actual accident rates were used as a measure of the applicability of the models to the study area. The results of this study are valuable for conducting an extensive road safety study on two-lane rural highways in British Columbia, primarily, and other regions of the world. === Applied Science, Faculty of === Civil Engineering, Department of === Graduate
