CURB-GUARDRAIL VAULTING EVALUATION
IMPACT EVALUATIONS ARE PRESENTED FOR SEVERAL CURB-GUARDRAIL COMBINATIONS. THE EVALUATIONS ARE CARRIED OUT BY CONSERVATIVELY ASSESSING THE POSSIBILITY THAT A VEHICLE WILL VAULT A GUARDRAIL AFTER IT IMPACTS A CURB. THREE PARAMETERS ARE EXAMINED: APPROACH VELOCITY, APPROACH ANGLE, AND GUARDRAIL SETBACK FROM THE CURB FACE. VAULTING ANALYSES ARE CARRIED OUT BY USING CURB-IMPACT SIMULATION DATA AS IMPUT TO AN ANALYTICALLY DERIVED VAULTING EQUATION. ALL CURB-GUARDRAIL COMBINATIONS SUBJECTED TO EVALUATION WERE FOUND TO BE FREE OF POTENTIAL VAULTING PROBLEMS. A REVIEW OF ALL KNOWN CURB-GUARDRAIL TESTS SHOWS NO IDENTIFIABLE CASES OF VAULTING BY STANDARD PASSENGER-CAR TEST VEHICLES. A REVIEW OF CURB-GUARDRAIL USE AND THE DEVELOPMENT OF OPTIMIZED CURB-GUARDRAIL CONFIGURATIONS ARE RECOMMENDED. /AUTHOR/
