Performance Evaluation of Cable Barriers on a 6:1 Sloped Median under MASH TL-3 Conditions

The main objective of the proposed research is to evaluate the performance of the current cable median barrier (CMB) design and two retrofit options under Manual for Assessing Safety Hardware (MASH) testing criteria. Finite element modeling and simulations will be employed as the major tool of the investigation. The evaluation will be based on TL-3 conditions, i.e., under the impact of an 1100C small passenger car and a 2270P pickup truck. All three CMB designs will be placed on a 6H:1V sloped median and impacted by these two vehicles at 100 km/hour and a 25 degree angle. The research will provide recommendations to North Carolina Department of Transportation (NCDOT) engineers and officials the better option of the two retrofit CMB designs under MASH safety criteria. The evaluation results of the current CMB design and the other retrofit design will also be provided to NCDOT engineers. The research results will help NCDOT officials in their ability to evaluate and communicate their efforts to enhance highway safety. The results will help further improve the performance of current roadside safety devices through economical retrofit options.
