RELATIONSHIP BETWEEN PERFORMANCE ON A SPEED ANTICIPATION TEST AND SELECTED DRIVER TASKS

THE RESULTS OF A LABORATORY SPEED ANTICIPATION TEST PREVIOUSLY INDICATED TO BE A RELIABLE DISCRIMINATOR BETWEEN DRIVERS WITH AND WITHOUT A HISTORY OF ACCIDENTS WERE CORRELATED WITH JUDGEMENTS OF CLEARANCE AND INTERSECTION TIME OF VEHICLES ON THE HIGHWAY. SUBJECTS WERE TESTED ON A SPEED ANTICIPATION TEST ON THREE TASKS. IN ONE OF THE CONDITIONS, A SUBJECT VIEWED A MOVING BLOCK WHICH DISAPPEARED BEHIND A BARRIER. THE SUBJECT ESTIMATED THE AMOUNT OF TIME REQUIRED FOR THE BLOCK TO REACH A POINT ON THE BARRIER. THE SECOND CONDITION INVOLVED A SUBJECTS ESTIMATION OF THE POINT OF INTERSECTION TWO POINTS OF VIEW - DIRECTLY IN FRONT OF THE APPARATUS AND FROM A TOP VIEW AT THE SIDE OF THE DEVICE. THE ROAD TEST CONSISTED OF THE SUBJECTS ESTIMATION OF CLEARANCE TIME AND INTERSECTION TIME. IN THE FORMER, THE SUBJECT ESTIMATED THE LAST POSSIBLE MOMENT IN WHICH HE FELT HE COULD SAFELY PASS A LEAD CAR IN THE FACE OF AN ONCOMING VEHICLE. IN THE LATTER TASK, THE SUBJECT ESTIMATED THE TIME IN WHICH AN APPROACHING VEHICLE WOULD INTERSECT WITH THE VEHICLE IN WHICH HE WAS RIDING. CORRELATIONS WERE COMPUTED BETWEEN THE VARIOUS MEASURES. IT WAS FOUND THAT PERFORMANCE ON THE SPEED ANTICIPATION TEST DID NOT PREDICT PERFORMANCE ON THE DRIVING TASKS. /AUTHOR/
