DRAGNET VEHICLE ARRESTING SYSTEM
THE "DRAGNET" VEHICLE ARRESTING SYSTEM CONSISTS OF A NET MADE OF STEEL CABLES ATTACHED AT EACH END TO METAL BENDER ENERGY-ABSORBING DEVICES. THE SYSTEM WAS SUBJECTED TO SIX FULL-SCALE AUTOMOBILE CRASH TESTS TO EVALUATE ITS PERFORMANCE IN STOPPING A SPEEDING VEHICLE OVER A RELATIVELY SHORT DISTANCE WITH ACCEPTABLE DECELERATION LEVELS. THE DECELERATIONS ENCOUNTERED WERE SIGNIFICANTLY LOWER THAN THOSE PRODUCED BY RIGID BARRIERS, AND COULD HAVE BEEN REDUCED EVEN MORE BY THE USE OF LESS RESTRAINING FORCE ON THE NET, RESULTING IN LONGER STOPPING DISTANCES. TIME-DISPLACEMENT AND DECELERATION DATA (AND OBSERVATION OF DAMAGE) FROM THE TEST SERIES, ALONG WITH THE PREDICTABILITY OF SYSTEM PERFORMANCE IN SPECIFIED SITUATIONS, INDICATE THAT PRACTICAL APPLICATION OF THE ARRESTING SYSTEM AT SUCH LOCATIONS AS DEAD ENDS OF ROADS, FERRY LANDINGS, AND HIGHWAY MEDIANS AT BRIDGE OVERPASSES IS FEASIBLE. /AUTHOR/
