VEHICLE CONTROL AND DRIVER INFORMATION PROCESSING

A METHOD IS DEVELOPED TO MEASURE THE DRIVERS ATTENTIONAL DEMAND. A VISOR-SHUTTER DEVICE WAS CONSTRUCTED, WHOSE LIGHT- DARK RATIO COULD BE CONTROLLED AND VARIED. UNDER MILD TRAFFIC CONDITIONS, THE DRIVER WOULD BE EXPECTED TO TOLERATE A RELATIVELY LONG DARK INTERVAL; UNDER HEAVY TRAFFIC, HE WOULD TOLERATE NO INTERRUPTION OF HIS VIEW OF THE ROAD. THE DEVICE WAS VALIDATED BY DETERMINING THE LONGEST DARK INTERVAL WHICH WOULD BE TOLERATED, WHEN THE CAR TRAVELLED AT VARIOUS SPEEDS ON A STRAIGHT SECTION OF INTERSTATE, AND ON A CURVED TRACK. A FORMULA WAS DEVELOPED TO EXPLAIN THE FACTORS INFLUENCING ATTENTIONAL DEMAND.
