The purpose of this research was to investigate the crashworthiness of a flared concrete median barrier with a flare rate of 20:1. The structural capacity and the occupant risk factors of the barrier system were evaluated with respect to MASH Test Level 4 criteria through computer simulations and full-scale crash testing.
MASH Test 4-12 involves a single unit truck (box truck) weighing 22,000 lb impacting a longitudinal barrier at a speed of 56 mi/h and an angle of 15 degrees.
