The six major areas of the AASHTO Strategic Highway Safety Plan--Drivers, Vehicles, Special Users, Highways, Emergency Medical Services, and Management--are subdivided into 22 goals, or key emphasis areas, that impact highway safety. One of these goals addresses the reduction of crashes and fatalities involving older drivers. This implementation guide provides engineering, planning, education, and policy guidance to highway agencies that desire to better accommodate older drivers special needs. Older drivers represent a subset of the driving population that deserves special attention. Aging affects a variety of skills needed for safe driving. In particular, the aging population experiences deterioration in physical, perceptual, and cognitive skills: reductions in strength, flexibility, and range of motion caused by arthritis or other conditions can negatively impact driving; many visual functions--including static and dynamic visual acuity, contrast sensitivity, and glare sensitivity--deteriorate with age; and normative aging most often affects cognitive changes, such as working memory, selective attention, and processing speed. |
