MEDIAN DESIGN AS IT AFFECTS CONSERVATION OF VEGETATION AND PLANTING FOR SCREENING HEADLIGHT GLARE AND TRAFFIC GUIDANCE

ACQUISITION OF SUFFICIENT RIGHT-OF-WAY TO ALLOW A WIDE MEDIAN STRIP ON MULTILANE HIGHWAYS, WHILE MORE COSTLY THAT A NARROW RIGHT-OF-WAY, MAY ULTIMATELY PAY FOR ITSELF THROUGH A NUMBER OF ADVANTAGES OF THE WIDER MEDIAN. FIRST, THE PROFILES CAN BE BETTER ADJUSTED TO EXISTING TERRAIN, WHICH SAVES CONSTRUCTION COSTS AND ENHANCES SAFETY. SECOND, NATIVE VEGETATION CAN USUALLY BE PRESERVED, WHICH SAVES ON REPLACEMENT, SEEDING, AND MAINTENANCE COSTS. THIRD, PLANTING IN WIDE MEDIANS IS MORE EFFECTIVE IN SCREENING TRAFFIC NOISE AND HEADLIGHT GLARE. IN THE DISCUSSION PERIOD THE AUTHOR NOTES THAT NEIGHTER HONEYSUCKLE NOR ROSA MULTIFLORA HAS PROVED A VEGETATION-CONTROL PROBLEM IN NEW JERSEY, BUT IN A MILDER CLIMATE IT VERY WELL MIGHT.
