Because of certain advantages of cable guardrail in comparison to W-beam guardrail this research was conducted to investigate the possibility of using a much larger percentage of cable guardrail. The computer program in this study was developed to expedite the lengthy and tedious cost-effectiveness and benefit-cost computations for (a) installing cable guardrail on roadside embankment, (b) installing W-beam safety guardrail on roadside embankments, l or (c) making embankment modifications. The findings in this study showed that in all situations investigated the installation of cable guardrail was more attractive than the installation of W-beam guardrail. The findings also showed that the configuration of the roadside embankment was a very significant factor in justifying the installation of guardrail. The work accomplished has demonstrated that the cost-effectiveness and benefit-cost computer program shows great potential as a managerial tool and the authors recommend that the program be incorporated into road design systems currently being used.
