DESIGNING SAFER ROADSIDE DITCHES (ABRIDGMENT)

THE DYNAMIC RESPONSE OF A VEHICLE DURING AN OFF-THE-ROAD MANEUVER DEPENDS ON MANY ROADWAY AND VEHICLE PARAMETERS. OF PRIMARY IMPORTANCE ARE SUCH FACTORS AS SPEED AND EXIT ANGLE, SLOPE STEEPNESS, SLOPE OF THE DITCH, AND OTHER RELATED GEOMETRIC AND OPERATIONAL FEATURES. THIS RESEARCH APPROACH TO INVESTIGATING ROADSIDE TRAVERSALS INVOLVED USE OF THE HIGHWAY-VEHICLE-OBJECT STIMULATION MODEL IN CONJUNCTION WITH 24 FULL-SCALE VEHICLE TESTS. THIS PAPER PRESENTS THE RESULTS OF THE STUDY. INCLUDED ARE DESCRIPTIONS OF THE FULL-SCALE METHODOLOGY AND A DISCUSSION OF THE RESULTS OBTAINED. TENTATIVE RECOMMENDATIONS ARE PRESENTED FOR DESIGN OF V-DITCHES AND SMALL-RADIUS ROUND DITCHES FOR VARIOUS COMBINATIONS OF SIDE AND BACK SLOPE.
