MEDIAN PLANTING FOR CONTROL OF HEADLIGHT GLARE IN NEW JERSEY

PLANTING OF MEDIAN STRIPS OF DIVIDED HIGHWAYS WAS FIRST DONE IN NEW JERSEY TO IMPROVE GENERAL HIGHWAY APPEARANCE. EXPERIMENTS IN RECENT YEARS HAVE DEMONSTRATED THE POSSIBILITY OF SCREENING OPPOSING TRAFFIC FROM HEADLIGHT GLARE BY PLANTING THAT DOES NOT OBSCURE VISIBILITY AT INTERSECTIONS OR CAUSE THE FORMATION OF SNOWDRIFTS ON THE TRAVELLED WAY. THREE TYPES OF SHRUB PLANTING WERE TRIED, RANGING FROM A CONTINUOUS HEDGE ON THE MEDIAN CENTER LINE TO A SERIES OF SHORT HEDGES OR "ANGLE PLANTINGS" PLACED AT INTERVALS OF 50 TO 60 FEET, AT AN ANGLE OF 15 TO 18 DEGREES FROM MEDIAN CURB TO CURB. ANGLE PLANTINGS APPEAR TO BE CONTINUOUS AT NIGHT, ECONOMIZE IN MATERIALS, DO NOT DANGEROUSLY OBSCURE VISION AT CROSSOVERS, AND LARGELY AVOID THE FORMATION OF SNOWDRIFTS. THESE ADVANTAGES ARE NOT SHARED BY CONTINUOUS HEDGES OR INFORMAL GROUP PLANTINGS FORMERLY USED. /AUTHOR/
