URBAN INTERSECTION STUDY, VOLUME IV: HEADWAY CHANGE DETECTION DURING CAR-FOLLOWING
INFORMATION ON HEADWAY CHANGE DETECTION IN CAR-FOLLOWING AT LOWER SPEEDS AND SHORTER HEADWAYS IS PRESENTLY NON- EXISTENT. THIS TYPE OF INFORMATION IS NECESSARY TO OBTAIN ACCURATE VALUES FOR DRIVER PARAMETERS WHICH PLAY AN IMPORTANT PART IN MODELS OF DRIVER BEHAVIOR DURING CAR- FOLLOWING. THE BASIC PURPOSE IS TO OBTAIN INFORMATION ON DRIVER DETECTION OF HEADWAY CHANGE UNDER VARIOUS CONDITIONS USING LOWER SPEEDS TYPICAL OF THOSE ENCOUNTERED AS DRIVERS APPROACH AN INTERSECTION. TWO CARS WERE USED TO OBTAIN 16 MILLIMETER FILMED RECORDINGS OF 24 CAR-FOLLOWING SITUATIONS. THIRTY-FIVE SUBJECTS VIEWED MOVIES OF ALL COMBINATIONS OF THE FOUR VARIABLES: VELOCITY-HEADWAY COMBINATION, MAGNITUDE OF ACCELERATION, ACCELERATION VS. DECELERATION, AND DURATION OF STEADY-STATE TIME BEFORE CHANGING HEADWAY. SUBJECTS' RESPONSES CONSISTED OF MOVING A BUTTON EITHER FORWARD OR BACKWARD CORRESPONDING TO HEADWAY DETECTIONS OF EITHER POSITIVE OR NEGATIVE DIRECTIONS RESPECTIVELY. THE TIME REQUIRED TO RESPOND WAS MEASURED. RAW DATA, MEAN RESPONSE LATENCIES, AND ANALYSIS OF VARIANCE ARE PRESENTED. /BPR/
