The purpose of the research was to investigate the effect of clear zone widths on accidents and to determine the 'break-even' traffic volumes and clear zone widths where accident savings equalled roadside improvement costs. Although sufficient data was not available to determine the statistically significant combined effects of clear zone widths and traffic volumes on accident frequency, some very logical trends were observed which provided the basis for accident prediction models and cost-safety-effective analyses.
