AN ANALYSIS OF FLASHING SYSTEMS

THE EFFECTIVENESS OF VARIOUS TYPES OF FLASHING DEVICES WAS INVESTIGATED AS TO REDUCING ACCIDENT RATES AT INTERSECTIONS ON THE RURAL STATE HIGHWAY SYSTEM. SEVERAL OTHER VARIABLES WERE CONSIDERED WHILE THE RELATIONSHIP BETWEEN TYPE OF FLASHING DEVICE AND REDUCTION IN ACCIDENT RATE WAS BEING FORMULATED. THESE VARIABLES WERE FLASHER CONSPICUOUSNESS, INTERSECTION GEOMETRICS, VOLUME, AND LINE-OF-SIGHT DISTANCE. THE RESULTS OF THIS STUDY INDICATED THAT THE REDUCTION IN INTERSECTION ACCIDENT RATE WAS OPTIMIZED THROUGH THE USE OF A PARTICULAR TYPE OF FLASHING DEVICE IN COMBINATION WITH CERTAIN INTERSECTION GEOMETRICS. IT WAS ALSO DETERMINED THAT THE VARIABLES OF INTERSECTION GEOMETRICS AND TOTAL INTERSECTION GEOMETRICS AND TOTAL INTERSECTION VOLUME PLACE LIMITING CONSTRAINTS ON THIS RELATIONSHIP. /AUTHOR/
