Summary
This report, produced by the University of Massachusetts Transportation Center for the Massachusetts Department of Transportation (MassDOT), addresses the growing safety and mobility challenges associated with the aging driving population. The research was motivated by rising older driver fatality rates, highly publicized crashes, and demographic projections indicating a significant increase in the population aged 65 and older. While older drivers have low crash involvement rates per capita, their crash rates per mile traveled increase markedly after age 75, and their physiological fragility leads to disproportionately high injury severity and fatalities. The study aimed to provide MassDOT’s Registry of Motor Vehicles with evidence-based recommendations for licensing renewal practices and alternative mobility options for non-driving older adults. The methodology comprised a multifaceted review of published and unpublished literature, analysis of Massachusetts-specific data, and a nationwide survey of State Departments of Transportation. Researchers conducted a demographic and spatial analysis using Census data and licensed driver records to map the distribution of older adults across Massachusetts. They analyzed older driver crash characteristics using data from the UMassSafe Traffic Safety Data Warehouse, including crash, citation, and hospital records. Additionally, the team reviewed existing state regulations and licensing policies, assessed the current infrastructure for alternative transportation (such as public transit and community organizations), and surveyed other states to identify best practices in licensing and mobility support. Key findings highlighted the disparity between older driver crash frequency and injury severity, noting that while crash rates are lower than those of younger drivers, the death rate per mile is significantly higher for those aged 75 and older. The analysis revealed gaps in the existing mobility network for non-driving older adults, with projected population growth likely to strain current services. The study also identified various licensing strategies used nationwide, such as graduated licensing and medical advisory boards, and evaluated their potential applicability to Massachusetts. The report concludes with eight specific recommendations for MassDOT. These include considering graduated licensing or de-licensing for older drivers, allocating resources for case-by-case cognitive and physical assessments rather than age-based restrictions, and reviewing gaps in alternative mobility coverage. Further recommendations involve creating an older adult mobility advisory board to coordinate stakeholders, identifying high-crash locations for targeted safety investigations, establishing mechanisms for older driver training programs, fostering public/private partnerships for transportation services, and developing a coordinated information resource for transportation alternatives. These measures aim to balance highway safety improvements with the preservation of mobility for older adults.
Key finding
Older drivers experience disproportionately high fatality rates per mile driven compared to other age groups, and existing alternative transportation networks in Massachusetts are projected to become insufficient as the older adult population grows.
