A COMPARISON OF PLANE AND CONVEX REAR VIEW MIRRORS FOR PASSENGER AUTOMOBILES, FINAL REPORT
PLANE AND CONVEX MIRRORS WERE COMPARED. EXPERIMENTS WERE PERFORMED ON THE EFFECTS OF VARIOUS CONVEXITIES IN RELATION TO EYE/MIRROR GEOMETRY, EYE ANOMALIES, TIME OF DAY, MIRROR SIZE, LEARNING REQUIRED TO USE CONVEX MIRRORS, AND THE USE OF COMBINATION MIRRORS. DATA ARE GIVEN FOR JUDGMENTS IN SPATIAL LOCALIZATION AND DETECTION PROBABILITIES FOR A WIDE RANGE OF INTERIOR PASSENGER-CARRYING BUSES: (3) THE NONUTILIZATION OF CONVEX MIRRORS PROVIDE AN IMPROVED PROBABILITY OF DETECTING OTHER AUTOMOBILES WHILE PROVIDING ACCURATE SPATIAL LOCALIZATION. CONVEX MIRRORS OF ABOUT 40-INCH RADIUS APPEAR TO BE A SATISFACTORY COMPROMISE IN TERMS OF CONVEXITY. IT IS RECOMMENDED THAT 40-INCH CONVEX MIRRORS BE INSTALLED ON LEFT AND RIGHT FRONT FENDER AREAS AND IN THE UPPER CENTER OF THE WINDSHIELD OF ALL PASSENGER CARS. FURTHER RESEARCH IS RECOMMENDED. A NEW SAFETY STANDARD FOR REARVIEW MIRRORS IS SUGGESTED. /HSL/
