ANALYSIS OF DRIVERS' CONTROL MOVEMENTS

DRIVER CONTROL MOVEMENTS WERE STUDIED IN TWO SIMPLE STEERING TASKS: DRIVING ALONG A STRAIGHT LANE AND ON A CIRCULAR PATH. IN BOTH CASES, DRIVERS WERE FOUND TO MAKE MOST OF THEIR CONTROL MOVEMENTS WITHIN A FAIRLY SMALL FREQUENCY RANGE. SPECTRAL ANALYSIS SHOWED PEAKS IN SPECTRAL DENSITY IN THE RANGE 0.15 TO 0.3 HZ. FOR THE CIRCULAR COURSE AND 0.1 TO 0.2 HZ. FOR MOST CASES ON THE STRAIGHT COURSE. IN A NUMBER OF TRIALS, SECONDARY PEAKS OCCURRED IN THE REGION 0.35 TO 0.60 HZ. AN ATTEMPT IS MADE TO EXPLAIN THESE RESULTS IN TERMS OF THE INFORMATION BEING USED BY THE DRIVER TO STEER THE CAR. IN THE CIRCULAR COURSE EXPERIMENT, EACH DRIVER DROVE THE VEHICLE WITH THREE DIFFERENT STEERING RATIOS. CHANGE OF STEERING RATIO DID NOT SHOW ANY CONSISTENT EFFECT ON THE FORM OF THE SPECTRUM OF STEERING-WHEEL ANGLE. /AUTHOR/
