| Abstract |
Since the concerns for safety of highway traffic safety facilities inherent in various environmental risk is increased, systematic performance, cost, and effect analysis process is needed for this. In case of median barrier among various traffic safety facilities, quantitative risk assessment is inevitable because it has lots of direct/indirect risk factors. Thus, this study suggests an advanced VE(Value Engineering) approach incorporating quantitative risk analysis. For the applicability, suggested VE approach considering alternative 1(140cm) and 2(127cm) is applied to median barrier in fields. Also, major improvement objects are extracted from governing factors of cost and performance based on functional analysis. It is concluded that the proposed risk assessment methodology will provide rational and practical solutions for best value and the approach could effectively applied for various traffic safety facilities by slight modification of suggest process. |
