With the graying of the Baby Boom generation, the number of older drivers on the road and the amount of driving they do continues to increase. However, along with this increase in the number of older drivers and their level of driving has come a sharp increase in the number of fatalities involving older drivers. Traffic safety improvements designed to make it easier for older drivers to navigate traffic are becoming increasingly important, as the largest generation in American history ages and seeks to maintain a level of mobility that matches their active lifestyles. Roadway improvements can help make driving safer for older Americans, as well as for the population at large. Older drivers are defined in this study as persons aged 70 or older, based on the age when most people start to experience some diminished physical capabilities associated with driving, such as vision, hearing, reaction times and flexibility. National Highway Traffic Safety Administration (NHTSA) data shows that traffic fatality rates begin to increase among drivers aged 70 and above.
