IMPACT TESTING OF LIGHTING POLES AND SIGN SUPPORTS, 1967-68

AN EVALUATION WAS MADE OF EXISTING TYPES OF HIGHWAY LIGHTING POLES AND SIGN SUPPORTS AND OF THE BENEFITS OF NEW DEVICES IN RELATION TO THE HAZARDS THEY PRESENT TO HIGH-SPEED TRAFFIC WHEN OUT-OF-CONTROL VEHICLES LEAVE THE TRAVELLED PORTION OF THE HIGHWAY. THE VEHICLES USED IN THE TESTS WERE STATION WAGONS, WEIGHING APPROXIMATELY 4,000 LB. THE STRUCTURES TESTED INCLUDED CONCRETE POLES AND ALUMINUM BREAKAWAY POLES (BASE-MOUNTED) AND DIRECTLY BURIED POLES AND SIGN SUPPORTS FOR DUAL CANTILEVERED SIGNS. PHOTOGRAPHS OF IMPACTS WERE TAKEN WITH HIGH-SPEED CAMERAS. DECELERATION DATA WERE RECORDED AND OBSERVATIONS MADE. RECOMMENDATIONS ARE GIVEN REGARDING THE USE OF DIFFERENT TYPES OF SUPPORTS IN SPECIFIC LOCATIONS, AND SUGGESTIONS ARE MADE FOR THE FUTURE RESEARCH NEEDS.
