GLARE SCREEN FOR DIVIDED HIGHWAYS
GLARE SCREENS IN USE TODAY INCLUDE PLANTING OF SHRUBBERY, WOOD OR METAL FENCES PLACED PARALLEL TO THE CENTERLINE OF THE HIGHWAY, AND INTERMITTENT FENCES OF WOOD OR METAL PLACED IN A LOUVERED PATTERN, OR PLACED AT 90 DEGREES TO THE CENTERLINE OF THE HIGHWAY. THE ADVANTAGES AND DISADVANTAGES OF EACH TYPE ARE DISCUSSED. THE SCREEN FOUND MOST SATISFACTORY IS A LINE OF EXPANDED METAL MESH, ERECTED IN THE MEDIAN STRIP, PARALLEL TO THE CENTERLINE OF THE HIGHWAY. DURING THE DAYTIME, THE FENCE DOES NOT INTERRUPT THE GENERAL VIEWING BY PASSENGERS TRAVELING IN AUTOMOBILES. THE MEDIAN STRIP, HEIGHT OF HEADLAMPS, AND HEIGHT OF DRIVERS' EYES ALL PLAY A PART IN LOCATING THE REQUIRED UPPER AND LOWER EDGES OF SCREEN. EXPERIMENTS ON THE VERTICAL POSITION OF SCREEN WITH RESPECT TO THE ROADWAY ARE DESCRIBED AND RECOMMENDATIONS ARE GIVEN.
