A MULTIVARIATE EVALUATION OF SELECTED DRIVER PERFORMANCE MEASURES

PSYCHOMOTOR PERFORMANCE DATA WERE COLLECTED FROM 80 SUBJECTS WHO DROVE THE HIGHWAY SYSTEMS RESEARCH, (HSR) CAR, AND 56 OF THIS NUMBER WHO WERE TESTED ON THE SIM-L-CAR POINT LIGHT SOURCE DRIVING SIMULATOR. SEVEN STEERING AND SPEED CONTROL VARIABLES WERE REPRESENTED IN THE HSR CAR BATTERY, WHILE TEN PERFORMANCE MEASURES WERE INCLUDED IN THE SIM-L- CAR BATTERY. DATA FROM EACH BATTERY WERE SUBJECTED TO BASIC STRUCTURE ANALYSIS AND TO A SERIES OF MULTIPLE DISCRIMINANT ANALYSES. RESULTS INDICATED THAT THE TEST SPACE OF EACH PERFORMANCE BATTERY WAS DEFINED BY FOUR ORTHOGONAL DIMENSIONS. THE MAJOR DIMENSION IN EACH CASE INVOLVED THE GENERAL LEVEL OF OPERATOR INPUTS TO THE VEHICULAR SYSTEM. THIS FINDING WAS SUPPORTED BY THE DISCRIMINANT ANALYSES, WHICH IN EACH CASE OF STATISTICALLY SIGNIFICANT BETWEEN- GROUPS DISCRIMINATION, PRODUCED THIS DISCRIMINATION ALONG AN OPERATOR INPUT DIMENSION. THE DISCRIMINANT ANALYSES REVEALED THE HSR BATTERY CAPABLE OF DISCRIMINATION AT THE .10 LEVEL OR BETTER BETWEEN HIGH AND LOW EXPERIENCE GROUPS, HIGH AND LOW VIOLATION GROUPS, AND BETWEEN GROUPS DEFINED BY HIGH VS. LOW OBSERVER RATINGS. THE SIM-L-CAR PRODUCED DISCRIMINATION, AT A SIMILAR LEVEL OF STATISTICAL SIGNIFICANCE, BETWEEN HIGH AND LOW EXPERIENCE GROUPS, AND A WRITTEN TEST OF DRIVING KNOWLEDGE. /AUTHOR/
