EVALUATION OF BREAKAWAY LIGHT POLES FOR USE IN HIGHWAY MEDIANS

CRASH TESTS WERE CONDUCTED TO DETERMINE THE IMPACT BEHAVIOR OF MEDIAN-MOUNTED LUMINAIRE SUPPORTS AND SECONDARY COLLISIONS OF VEHICLES STRIKING DOWNED POLES ON A TRAFFIC LANE. A RELATIVE HAZARD INDEX WAS DEVELOPED TO DESCRIBE THE RELATIVE HAZARD CREATED BY THE PROXIMITY AND FREQUENCY OF LUMINAIRE SUPPORTS. IT WAS FOUND THAT, FROM A RELATIVE HAZARD STANDPOINT, MEDIAN-MOUNTED LUMINAIRE SYSTEMS PRODUCE LESS HAZARD THAN HOUSE-SIDE SYSTEMS FOR MEDIAN WIDTHS OF 30 FT OR GREATER. /AUTHOR/
