A PRELIMINARY COST-BENEFIT STUDY OF HEADLIGHT GLARE REDUCTION

HEADLIGHT GLARE IS CONSIDERED TO BE A SERIOUS DRIVING HAZARD BY ALMOST EVERY NIGHTTIME VEHICLE DRIVER. A NUMBER OF MEANS EXIST FOR ELIMINATING OR GREATLY REDUCING GLARE WHILE PERMITTING INCREASED ILLUMINATION OF THE ROADWAY AHEAD OF THE DRIVER, AND THESE MUST BE CAREFULLY CONSIDERED BEFORE PROPOSING ANY MAJOR CHANGE IN NIGHTTIME DRIVING PRACTICES FOR THE ENTIRE NATION. THE USE OF POLARIZED LIGHTING SYSTEMS ON ALL VEHICLES WILL VIRTUALLY ELIMINATE GLARE FROM OPPOSING VEHICLES, WHILE PROVIDING MORE ILLUMINATION FOR THE HIGHWAY SCENE AHEAD OF THE VEHICLE THAT IS NOW AVAILABLE. ANOTHER POSSIBLE SOLUTION TO THE GLARE AND VISIBILITY PROBLEM MAY BE THE ILLUMINATION OF ALL HIGHWAYS WITH FIXED LIGHTING SYSTEMS TO PROVIDE A LEVEL OF ILLUMINATION WHICH WOULD MAKE VEHICLE HEADLAMPS UNNECESSARY, EXCEPT PERHAPS AS MARKER LIGHTS. THIS STUDY PRESENTS THE RELATIVE COSTS OF THE PROVISION OF ADEQUATE LIGHTING FOR DRIVING SAFETY AND AGAINST THE VALUE OF BENEFITS TO BE OBTAINED BY SUCH IMPROVED NIGHT VISION. IT MUST BE CONSIDERED AS ONLY A FIRST-STAGE, PRELIMINARY REVIEW OF THE COST AND BENEFIT FACTORS OF CONCERN. /AUTHOR/
