Summary
This study addresses the transportation needs and safety concerns of drivers aged 55 and older in Virginia, motivated by demographic trends showing a growing older driving population and safety data indicating higher crash rates per mile driven for this group. The research aimed to identify specific problems faced by older Virginians, compare these findings to previous studies, and review existing interventions. The study was conducted by the Virginia Transportation Research Council between 1989 and 1992. The methodology involved a multi-step approach combining qualitative and quantitative data. First, ten focus groups were held across six Virginia localities, stratified by population size and region, to identify broad themes. These findings informed the development of a survey instrument for 100 in-depth telephone interviews with randomly selected licensed drivers aged 55 and older. The interview sample was stratified by age, gender, and community size to ensure representativeness. Additionally, the researchers reviewed existing literature on older driver interventions and programs. The results identified four primary categories of concern: roadway information, visibility, complex driving environments, and expectancy violations. Older drivers frequently cited issues with road signs, including inconsistent placement, confusing content, and insufficient advance warning, particularly at high speeds. Visibility problems were attributed to poor sight distances, inclement weather, night driving, and large trucks. Complex environments involving heavy traffic and high speeds were also problematic. Despite these challenges, older drivers reported engaging in "self-regulating" behaviors, such as avoiding night driving, peak traffic, and complex intersections. They also acknowledged age-related declines in reflexes and night vision but emphasized their experience and patience. The study found that older drivers place high importance on driving for maintaining independence, with 95% citing it as essential for their lifestyle. The significance of this research lies in its detailed identification of specific roadway design and operational factors that hinder older drivers, providing evidence for targeted infrastructure improvements. The findings replicate previous studies, confirming that older drivers adapt through self-regulation but still face significant challenges with current roadway designs, which often date back to the 1940s. The review of interventions noted that evidence regarding the effectiveness of older driver improvement courses and other countermeasures in reducing accidents remains largely inconclusive due to data limitations. The report suggests that addressing issues like sign clarity, signal timing, and traffic flow could enhance safety and mobility for this growing demographic.
Key finding
Older drivers reported significant difficulties with confusing sign content, lack of advance warning, visibility issues caused by weather and large trucks, and complex driving environments involving heavy traffic and other drivers' behavior.
