The purpose of this research was to develop a Manual for Assessing Safety Hardware (MASH) Test Level 3 (TL-3) compliant transition between a median guardrail and median concrete barrier, and then test the design according to MASH TL-3 crash testing guidelines. The design was developed using finite element computer simulations. This report provides details on the computer simulations, the Texas Department of Transportation (TxDOT) median transition system, the crash tests and results, and the performance assessment of the median transition for MASH TL-3 transition evaluation criteria. The TxDOT median transition met the performance criteria for MASH TL-3 transitions.
