A FACTOR ANALYTIC APPROACH TO THE DRIVING TASK

PSYCHOMOTOR PERFORMANCE DATA WERE COLLECTED FROM 80 SUBJECTS WHO DROVE THE HSR CAR, AND 56 WHO WERE TESTED ON THE SIM-L-CAR POINT LIGHT SOURCE DRIVING SIMULATOR SIX STEERING AND SPEED CONTROL VARIABLES WERE REPRESENTED IN THE HSR CAR BATTERY, WHILE NINE VARIABLES WERE INCLUDED IN THE SIM-L-CAR BATTERY. DATA FROM EACH BATTERY WERE SUBJECTED TO A PRINCIPAL AXIS FACTOR ANALYSIS WHICH EMPLOYED AN ORTHOGONAL ROTATION AS A FINAL STEP. RESULTS INDICATED THAT THE TEST SPACE OF THE HSR CAR BATTERY WAS DEFINED BY THREE ORTHOGONAL DIMENSIONS REPRESENTING STEERING CONTROL, SPEED CONTROL, AND OPERATOR INPUT VARIABILITY. FOR THE SIM-L-CAR FOUR DIMENSIONS WERE EXTRACTED BY THE ANALYSIS. THESE INVOLVED STEERING CONTROL, TRACKING ERROR PRODUCTION, SPEED CONTROL, AND OPERATOR INPUT VARIABILITY. /HSL/
