Physician knowledge, assessment, and reporting of older driver fitness.

ABSTRACT Physicians have the potential to serve as an important portal for information gathering, assessment, counseling, and reporting older driver fitness, as almost all older adults require medical care and have a primary care physician. However, there are few studies that have evaluated physician knowledge about, attitudes toward, and performance of older driver fitness assessment. Two pilot studies were conducted to assess physician knowledge and attitudes and aid understanding of physician knowledge of legal reporting requirements regarding older driver medical fitness.

Speed choice and driving performance in simulated foggy conditions.

Driving in fog is a potentially dangerous activity that has been investigated in a number of different ways; however, most have focused on identifying the underlying perceptual changes that result in an inability to perceive speed of vehicle motion. Although the previous research has identified the perceptual changes associated with driving in fog and shows that people are highly likely to perceive their speed to be higher than it actually is, these research studies have not investigated driving behavior when drivers are allowed to maintain speed as they feel appropriate and make use of the vehicle's speedometer. In addition, much of the existing research focuses on speed perception and presents a limited view of other driving performance metrics in terms of lane keeping and event detection.
