STUDIES OF DRIVER-AUTOMOBILE INTERFACES, SEPTEMBER 1965

THE FIRST PAPER IN THIS VOLUME, AN AUTOMOBILE SIMULATOR, CONTAINS A DISCUSSION OF THE TWO-CAR SIMULATOR WHICH WAS USED IN MOST OF THE CAR FOLLOWING STUDIES, SOME APPLICATIONS OF THIS SIMULATOR ARE DISCUSSED IN THE SECOND PAPER, APPLICATIONS OF THE AUTOMOBILE SIMULATOR. DATA OBTAINED FROM SIMULATOR STUDIES WAS THEN USED TO DEVELOP THE DECISION POINT MODEL OF CAR FOLLOWING. THIS MODEL, TOGETHER WITH SOME CAR- FOLLOWING STABILITY STUDIES ARE DISCUSSED IN THE THIRD PAPER, STUDIES ON TRAFFIC FLOW MODELS. VELOCITY THRES- HOLD DATA, OBTAINED UNDER SIMULATED DAYTIME CAR-FOLLOWING CONDITIONS, WAS USED TO DEVELOP A MORE REFINED MODEL OF THE DRIVER-VEHICLE SYSTEM-THE ACTION POINT MODEL. BOTH QUALITA- TIVE AND QUANTITATIVE ASPECTS OF THIS MODEL ARE DISCUSSED IN THE FOURTH PAPER, THE ACTION POINT MODEL OF THE DRIVER- VEHICLE SYSTEM. THE EXPERIMENTAL DESIGN USED TO OBTAIN THE VELOCITY THRESHOLD DATA IS DISCUSSED IN THE FIFTH PAPER, VELOCITY THRESHOLDS IN CAR FOLLOWING, AND A BRIEF DESCRIPTION OF THE ACTION POINT MODEL IS CONTAINED IN THE SIXTH PAPER, A PROPOSED MODEL FOR THE DRIVER-VEHICLE SYSTEM. ADDITIONAL VELOCITY THRESHOLD DATA WERE OBTAINED UNDER SIMULATED NIGHTTIME CAR-FOLLOWING CONDITIONS. A DISCUSSION OF BOTH THE EXPERIMENTS AND RESULTS ARE CONTAINED IN THE SEVENTH PAPER, VELOCITY THRESHOLDS IN CAR FOLLOWING AT NIGHT THE RESULTS OBTAINED FROM LATTER THRESHOLDS STUDIES, ALSO UNDER SIMULATED NIGHTTIME DRIVING CONDITIONS, ARE CONTAINED IN THE EIGHTH PAPER, VISUAL MOTION THRESHOLDS FOR SIMULATED NIGHT DRIVING. THE THRESHOLD STUDIES, TOGETHER WITH AN EXAMINATION OF THE ACTION POINT MODEL, REVEALED THAT THE FINITE TIME REQUIRED FOR A DRIVER TO DETECT SLOW RELATIVE MOTION OF A LEAD VEHICLE IS A MAIN FACTOR CAUSING HEADWAY VARIATION IN CAR FOLLOWING. ATTEMPTS TO OVER-COME THIS FUNDAMENTAL LIMITATION ARE DISCUSSED IN THE LAST PAPER IN THIS VOLUME, DRIVER-AUTOMOBILE INTERFACES. IN PARTICULAR, IT IS FOUND THAT A TACTILE AIDING DEVICE BUILT INTO THE HEAD OF A CONTROL STICK MAY BE USED TO GREATLY IMPROVE THE PERFORMANCE OF THE DRIVER-VEHICLE SYSTEM UNDER SIMULATED CAR FOLLOWING CONDITIONS. THIS LATER STUDY WAS INITIATED IN ORDER TO DETERMINE A SATISFACTORY MANUAL MODE FOR USE WITH THE AUTOMATIC SYSTEM FOR LONGITUDINAL CONTROL.
