Heads Up Display (HUD) technologies are being developed to assist drivers and reduce safety hazards. The current study used the Lane Change Task (LCT) and a Peripheral Detection Task (PDT) divided into high and low workload tracks to assess effects of employing a HUD to alert drivers to moving objects in their periphery that are possible hazards. The intent of the current study was to determine whether visual warnings displayed in either color, flashing, or color and flashing formats, would improve detection of moving stimuli without adversely impacting driving ability. Results indicated that the PDT had no significant effect on LCT performance. However, significant main effects of warning format and workload on reaction times, false alarm rates, and sensitivity were obtained. Performance on the PDT task was best when the warnings were non-flashing and yellow, especially in the low workload condition. Explanations of performance on both tasks are discussed.
