PRELIMINARY EXAMINATION OF DRIVER EYE FIXATIONS ON RURAL ROADS: INSIGHT INTO SAFE DRIVING BEHAVIOR. INTERIM REPORT

This report describes an investigation of driver eye patterns on straight and curved rural roads. Eight participants (four under 30 years, four over 60 years) drove on a 4.6 mile (7.4 km), two-lane road while wearing an eye mark camera to record eye fixations. While data were collected for the entire route, only four road sections were of interest (one straight section and three left curves (3, 13 and 21 degrees)). In addition to eye fixation data, driving performance measures (speed and lane deviation) were recorded. Analysis of the results indicates that fixations to oncoming cars on the 3 degree curve (103 msec) were shorter than fixations to oncoming cars on the other two curves (588 msec) and the straight section (541 msec). On the straight section, there were more fixations to the far field (59%) than on the three curves (18%, 37%, and 28%, respectively). The probability of fixating on road features also varied with road curvature. On the straight section, the probability of fixating on the far field is 40%, whereas on curves it ranges from 10% (3 degree curve) to 28% (13 degree curve). On curves, the driver is more likely to distribute his/her eye fixations more evenly over the road features. From the driving data, there were no indications of excessive lane deviation or speed. The data from this study will be entered into a simulation model that will describe driver eye fixation patterns, and the model will be validated. The ultimate goal of the simulation modeling will be to describe driver eye fixations given various road and driver characteristics. This will provide baseline data for driving that will lead to safe and easy to use in-vehicle displays by helping to identify the attentional demands of driving.
