Analysis of Visual Attention and Useful Field of View among Ezperienced, Inezperienced and Older Drivers
Older and young inexperienced drivers are involved in more fatalities than adult experienced drivers. A critical issue in reducing these accident numbers is to improve our understanding of the association between the visual attention of these three groups of drivers (older, young inexperienced, adult experienced) and their useful field of view (UFOV) when driving. We estimated driver saccadic amplitudes, fixation durations, and number of fixations for ten different traffic scenarios using a driving simulator. Of these ten scenarios, six presented potential accident events to the drivers. To estimate saccadic amplitudes, fixation durations, and number of fixations, eye position data was analyzed during a ten-second interval, lasting from five seconds before to five seconds after the traffic situations appeared. Results suggest that eye movements, fixation durations, and number of fixations change as a function of the visual stimuli presented in each traffic situation. The difference among age groups was statistically significant for fixation time and number of fixations, but not for total eye movement. Based on these results, we expressed UFOV as a function of saccadic amplitude between fixation points and durations, and estimated the ranges of a sequence of UFOV during the 10-second period for each traffic situation. Results suggest UFOV range does depend on visual stimuli, driving speed, age group, and time of event.
