N2 - Studies show that older drivers are at a greater risk for crashes at unsignalized intersections. The objective of this study is to examine the visual search pattern of older drivers as they begin one of three drive maneuvers (i.e., left turn, right turn, and straight across) at two different rural expressway intersections (i.e., high and low crash areas). Twenty drivers participated in this study with 10 older drivers (65-80 years old) and 10 middle-aged drivers (35-55 years old) used as a comparison group. Results show that older drivers used significantly less search time to get ready for all maneuvers when compared to middle-aged drivers. There was also an interaction effect with older drivers taking significantly less search time during higher traffic volumes. Middleaged drivers would search for potential hazards and wait for an appropriate gap distance before entering into the intersection.
