Using an instrumented vehicle, we have studied several aspects of the on-road performance of healthy and diseased elderly drivers. One goal from such studies is to ascertain the type and frequency of driving safety errors. Because the judgment of such errors is somewhat subjective, we applied a taxonomy system of 15 general safety error categories and 76 specific safety error types. We also emp...

How the brain monitors ongoing behavior for performance errors is a central question of cognitive neuroscience. Diminished awareness of performance errors limits the extent to which humans engage in corrective behavior and has been linked to loss of insight in a number of psychiatric syndromes (e.g., attention deficit hyperactivity disorder, drug addiction). These conditions share alterations i...

The road accidents and the resulting fatalities are on a rise in India. Statistics point out that a large majority of the accidents involve novice drivers, and are a result of human errors. In order to study the causes of these human errors, we aim to study the effect of driver training on novice drivers. Improper visualization of road transportation system, overestimation of driving skills and...

OBJECTIVE To find an association between cognitive-perceptual problems of older drivers and unsafe driving performance during simulated automobile driving in a virtual environment. DESIGN Cross-sectional study. SETTING A driver evaluation clinic in a rehabilitation hospital. PARTICIPANTS Fifty-five drivers aged 65 years or older and 48 drivers in their late twenties to early forties. ME...

BACKGROUND High rate of motor vehicle accidents' have been associated with poor vision. Studies on drivers from elsewhere other than health institutions have found abnormal visual acuities. The aim of this study is to determine prevalence of refractive errors and the attitude to spectacle wear among drivers of public institutions studied. METHODS A cross sectional population study of all 99 m...

Dingus and colleagues recently estimated crash odds ratios (ORs) for “driver behavior errors” (hereafter, “Behaviors”) in the Strategic Highway Research Program Phase 2 naturalistic driving study. Behaviors are illegal, improper, aggressive, and/or reckless driving maneuvers. For example, the Dingus study OR estimate for “Speeding over limit and too fast for conditions,” (hereafter, “Speeding”)...

OBJECTIVE Older driver research has mostly focused on identifying that small proportion of older drivers who are unsafe. Little is known about how normal cognitive changes in aging affect driving in the wider population of adults who drive regularly. We evaluated the association of cognitive function and age with driving errors. METHOD A sample of 266 drivers aged 70 to 88 years were assessed...
