IMPACT PERFORMANCE AND A SELECTION CRITERION FOR TEXAS MEDIAN BARRIERS
The impact performance of the Texas Metal Beam Guard Fence median barrier (MBGF) was determined and compared with that of the Texas Concrete Median Barrier (CMB). The MBGF consists of two standard W-shaped guardrails mounted back-to-back on a 6 WF 8.5 support post whereas the CMB is a solid concrete barrier. The impact performance of the MBGF was determined from a combination of crash tests and from crash simulations by the Highway-Vehicle-Object-Simulation-Model (HVOSM). Full-size automobiles (approximately 4,000 lb) were used in both the crash tests and the crash simulations. A close comparison of test and simulated results verified the accuracy of the HVOSM in simulating impacts with the MBGF. The impact performance of the CMB was obtained from another study.
