Abstract

Studies were performed to obtain comparable information on 3 different concrete safety shapes impacted by both standard sedans and subcompact sedans at 96.6 km/h (60 mph) and at angles of 7 and 15 degrees. Diagrams are used to illustrate barrier profiles. The test results (tabulated) show the vehicle roll in all tests for the MB6 shape and for the new configuration F. An exception was the 15-deg test with configuration F. A higher roll angle was observed in the test although vehicle climb was less. Vehicle roll occurred with the MB6 shape during a subcompact crash at 91.9 km/h (5.7 mph) and angle of 16.5 deg. Vehicle damage was generally less with MB6 except for rollover. Average vehicle decelerations indicate that similar performance can be expected with the 3 shapes, but the new configuration F shape appears to provide lower values.
