ENERGY-ABSORBING CORRUGATED METAL HIGHWAY BUFFER

A NEW CONCEPT IN ENERGY-ABSORBING HIGHWAY BUFFERS WAS DEVELOPED AND TESTED WITH SCALE MODELS. THE BUFFER IS MADE OF CORRUGATED-METAL ELEMENTS THAT DEFORM PLASTICALLY ON IMPACT AND ABSORB THE ENERGY OF THE IMPACTING VEHICLE. THE BUFFER HAS A PARBOLIC SHAPE TO FORM A GRADUAL TRANSITION BETWEEN AN ENERGY-ABSORBING BUFFER FOR FRONTAL IMPACTS AND AN ENERGY-ABSORBING GUARDRAIL FOR GLANCING, SIDE IMPACTS. THE MODEL BUFFER WAS FOUND TO PERFORM WELL IN A VARIETY OF SITUATIONS INCLUDING HEAD-ON, ANGLED, AND GLANCING IMPACTS. SCALE-MODEL TESTING WAS FOUND TO BE A VALUABLE TOOL; TESTS WERE CONDUCTED FOR A SMALL FRACTION OF THE COST AND TIME OF FULL-SCALE TESTS. ADDITIONAL SCALE-MODEL TESTS AND SOME FULL-SCALE TESTS WILL NEES TO BE CONDUCTED BEFORE THE DESIGN IS COMPLETED. /AUTHOR/
