DETECTION OF VEHICLE VELOCITY CHANGES IN CAR FOLLOWING

A SURVEY IS MADE OF PAST WORK ON THE DETECTION OF VEHICLE VELOCITY CHANGES IN CAR-FOLLOWING. THE HYPOTHESIS IS MADE THAT DETECTION IS DEPENDENT ON CHANGES OF THE VISUAL ANGLE SUBTENDED BY THE LEAD VEHICLE AT THE EYE OF A SUBJECT IN THE FOLLOWING VEHICLE, AND ALSO ON THE TIME RATE OF CHANGE OF THIS VISUAL ANGLE. REANALYSIS OF EXPERIMENTAL DATA GIVES RESULTS CONSISTENT WITH THIS HYPOTHESIS. IT APPEARS THAT WHEN RATE OF CHANGE OF VISUAL ANGLE IS SMALL, IT HAS A DEGRADING EFFECT ON DETECTION BY CHANGES IN VISUAL ANGLE. /AUTHOR/
