WARRANTS FOR GUARDRAILS ON EMBANKMENTS

THE HIGHWAY-VEHICLE-OBJECT SIMULATION MODEL, A COMPUTER MODEL THAT DECRIBES AN AUTOMOBILE AND IS CAPABLE OF PREDICITING THE DYNAMIC RESPONSE OF THE AUTOMOBILE TRAVERSING SELECTED TERRAIN, WAS USED TO STUDY THE BEHAVIOR OF A STANDARD-SIZED AUTOMOBILE TRAVERSING EMBANKMENTS SIDE SLOPES AT VARIOUS SPEEDS AND DEPARTURE ANGLES. THE ACCELERATIONS OBTAINED WERE USED TO COMPUTE A SEVERITY INDEX THAT WAS THEN COMPARED WITH A SIMILARLY COMPUTED SEVERITY INDEX (FROM ACTUAL CRASH DATA) OF A VEHICLE IMPACTING A W-BEAM GUARDRAIL WITH POSTS ON 61/4-FT SPACING. AN EQUAL-SEVERITY CURVE WAS THEN DEVELOPED THAT CAN BE USED AS A GUARDRAIL INSTALLATION CRITERION. /AUTHOR/
