STUDY OF BOX-BEAM MEDIAN BARRIER ACCIDENTS

STUDY WAS PERFORMED TO EVALUATE THE EFFECTIVENESS OF A NEWLY INSTALLED BOX-BEAM MEDIAN BARRIER WITH RESPECT TO ITS ABILITY TO SUSTAIN VEHICLE DAMAGES AND PREVENT MEDIAN CROSSINGS. APPROXIMATELY 9.4 MILES OF BOX BEAM MEDIAN BARRIER WAS INSPECTED MONTHLY FOR A 12-MONTH PERIOD AND DAMAGES WERE CLASSIFIED AND RECORDED. OF THE 204 DAMAGES RECORDED, 153 (75 PERCENT) WERE CLASSIFIED AS MINOR, 41 (20 PERCENT) MEDIUM, AND 10 (15 PERCENT) MAJOR, ONE OF WHICH WAS A BREAKTHROUGH. THE DAMAGES SUSTAINED BY THE BOX-BEAM BARRIER REFLECT ITS DESIGN CONCEPT, I.E., STRONG RAIL AND WEAK POSTS. EIGHTY-FOUR PERCENT OF ALL THE BOX-BEAM DAMAGES WERE NOT REPORTED TO THE POLICE, INDICATING THAT MOTORISTS WHO HIT THE BOX-BEAM BARRIER WERE ABLE TO MAINTAIN CONTROL OF THEIR VEHICLES AND CONTINUE ON THEIR TRIPS. /AUTHOR/
