ROLE OF PERIPHERAL VISION AND TIME SHARING IN DRIVING

THE ROLE OF EXTRA-FOVEAL AND FOVEAL VISION IN THE VISUAL INFORMATION ACQUISITION PROCESS OF THE DRIVER, AND THE EFFECT OF A DRIVER'S VISUAL INFORMATION ACQUISITION BEHAVIOR ON HIS DRIVING PERFORMANCE ARE INVESTIGATED. IT WAS FOUND THAT DRIVERS ACQUIRE CONSIDERABLE AMOUNTS OF INFORMATION THROUGH EXTRA-FOVEAL VISION FOR BOTH LATERAL AND LONGITUDINAL CONTROL PERFORMANCE. FOVEAL VISION, BECAUSE OF ITS FINER DISCRIMINATION CAPABILITIES, CAN PROCESS INFORMATION MORE ACCURATELY AND AT HIGHER SPEEDS, BUT IT COVERS ONLY A SMALL PORTION OF THE TOTAL VISUAL FIELD AVAILABLE TO A DRIVER. THE RESULTS OBTAINED IN THIS EXPERIMENT HAVE IMPLICATIONS IN MANY DESIGN PROBLEMS WHERE DEGRADATION IN BOTH LATERAL AND LONGITUDINAL CONTROL PERFORMANCE IS CRITICAL AND A NUMBER OF OTHER SPATIALLY SEPARATED TASKS SUCH AS READING SIDE-MOUNTED SIGNS AND JUDGING MOTION CHARACTERISTICS OF MERGING VEHICLES EXIST. /HSL/
