VEHICLE REDIRECTION EFFECTIVENESS OF MEDIAN BERMS AND CURBS

Results of an analytical investigation using the Highway-Vehicle-Object Simulation Model (HVOSM) to determine and evaluate the capability of earth berms and curbs for redirecting vehicles that accidentally leave the roadway are presented. Two median berm cross section designs and three curb configurations contacted by both a full size and a compact automible traveling at speeds between 20 and 80 MPH and departing the roadway at angles between 3 and 25 degrees were simulated in over 80 computer runs. Some gross comparisons of model predictions with results of experimental berm traversals and curb impacts reported in the literature are also presented which indicate reasonably good correlation.
