Abstract:The number of drivers aged 65 or older has been increasing rapidly over the last ten years. There were more than 40 million elderly drivers in United States, which is a 50% increase from 1999. While there is an increase in mobility and independence associated with driving, the high risk of being injured or killed in a motor vehicle accident involving older drivers has become a major concern in society today. Older drivers accounted for about 17% of fatal and 10% of injury caused traffic crashes in 2013. The over-representation of older drivers in at-fault crashes and collision related fatalities may be associated with physical frailty and/or impairments that lead to failure to yield the right of way, unseen objects, and failure to heed stop signs or signal. Intersections are particularly dangerous for elderly drivers. Because older drivers had significantly fewer glances toward the turning direction and other vehicle traffic for hazards when turning at T-intersections or at four way intersections, they may have a greater likelihood of a critical incident. For elderly drivers, they are more likely to crash at intersections with the presence of signals and signs, probably because that dealing with them requires larger amount of visual and mental resource, which may be a greater challenge for the elderly considering their decreased sensory, perceptual, cognitive and motor performance. Recent studies have identified advances in technology that make it possible to reduce the unsafe behaviors that lead to fatal crashes at intersections by providing customized feedback and training to older drivers in the form of alerts. The purpose of this study is designing some visual and auditory alerts which can effectively help older drivers increase their detection of potential hazards without interfering with other driving tasks.
