In-Service Performance Evaluation of a Cable Median Barrier System on Interstate Highways
Under an experimental features study requested by the Federal Highway Administration, the Indiana Department of Transportation installed a proprietary cable median barrier system, i.e., the Brifen four-rope wire rope safety fence (WRSF), to assess issues in installation, maintenance, and repair of this WRSF system and to evaluate its in-service performance. The WRSF system was installed at two different sites, respectively. A total of 157 median crashes were examined to evaluate the safety performance of the WRSF system in terms of the effectiveness in intercepting errant vehicles and crash outcomes. Field visits were conducted to identify possible improvements to the layout of the WRSF system according to the roadway configurations. The construction and repair costs were examined to provide useful information for cost-effectiveness analysis. Models were developed to enable an in situ estimate of the damage to the WRSF system after each crash. This paper presents the process and findings for the field installation, safety evaluation, and cost analysis.
