EQUIPMENT AND PROCEDURES FOR MEASURING GLARE FOR MOTOR VEHICLES

A PROCEDURE AND DESCRIPTION OF EQUIPMENT FOR MEASURING GLARE FROM A DRIVER'S OWN VEHICLE ARE PRESENTED. THE PROCE- DURES DEVELOPED ARE BASED ON DISABILITY GLARE THEORY AS AP- PLIED TO FOVEAL VISION. TWO PIECES OF APPARATUS WERE CON- STRUCTED TO PROVIDE THE MEASUREMENT CAPABILITY. ONE OF THEM SIMULATES DIFFUSE SKY GLARE AND THE OTHER SIMULATES DIRECT SOLAR GLARE. METHODS OF COMBINING DATA FROM THESE MEASURE- MENTS ARE PRESENTED ALONG WITH SCALING LAWS SELECTED TO PRO- VIDE A VALUE FOR GLARE AS IT WOULD BE UNDER NATURAL DAYLIGHT CONDITIONS. A STANDARD FOR ALLOWABLE GLARE LEVELS FROM THE VEHICLE IS DEVELOPED WHICH IS INDEPENDENT OF THE MEASUREMENT PROCEDURE. TEST RESULTS FROM A PASSENGER CAR ARE PRESENTED AND COMPARED WITH THIS STANDARD. RECOMMENDATIONS FOR IMPROVEMENTS TO THE APPARATUS AND ADDITIONAL RESEARCH REQUIREMENTS FOR IMPROVEMENT TO THE THEORY ARE MADE. /AUTHOR/
