Summary
This study addresses the growing public health concern regarding roadway safety among senior drivers, a demographic projected to constitute 25% of the U.S. population by 2024. As accident and injury risks increase with age, particularly for those with cognitive impairments like dementia, there is a need for effective assessment tools. The research aims to evaluate the feasibility of using state-of-the-art driving simulators as a supplemental evaluation mechanism for senior drivers, complementing traditional in-clinic and in-vehicle assessments. The goal is to identify if simulators can safely and effectively challenge drivers in scenarios that are logistically difficult or unsafe to replicate in real vehicles, thereby providing standardized metrics for driving performance. The researchers conducted a pilot study with ten participants (seven males, three females) aged 65 and older, recruited from senior community centers in Western New York. Each participant underwent a two-part evaluation process. First, at the University at Buffalo, participants completed cognitive screenings (Mini-Mental State Examination and Montreal Cognitive Examination) and drove in a motion-based simulator for approximately 18 minutes across three increasing levels of complexity. Performance was scored on ten categories, including lane maintenance and hazard management. Second, participants visited Erie County Medical Center for clinical assessments of motor, sensory, and visual skills, followed by a 20–30 minute in-vehicle road test in a dual-equipped Ford Taurus. Data collected included simulator scores, clinical test results (such as brake reaction time and Trail Making B), in-vehicle performance scores, and simulator sickness metrics. The results indicated that most participants scored in the normal range for cognitive exams and passed their in-vehicle evaluations, with only one driver receiving a "daytime only" restriction due to vision issues. However, simulator performance scores were generally lower than in-vehicle scores, which the authors attributed to participants being novices in the simulated environment rather than actual driving deficits. Simulator sickness was a significant issue; while most participants experienced mild symptoms, one participant vomited, and several reported discomfort with the brake pedal feel and multi-screen turning mechanics. Despite these technical limitations, all participants were passed by the simulator evaluator, though three were passed with reservations. Participants acknowledged the potential value of simulators but highlighted specific usability flaws that contributed to their discomfort. The study concludes that driving simulators hold promise as a safe, repeatable, and cost-effective tertiary evaluation tool for senior drivers, particularly those with suspected cognitive impairment. While the current pilot study revealed technical shortcomings in the simulator hardware that induced sickness and affected performance metrics, it successfully demonstrated the feasibility of the approach. The authors recommend future studies with larger, more cognitively diverse populations to validate the hypothesis that simulators can detect performance declines in drivers with dementia. Ultimately, refining simulator fidelity and usability could allow for the broad deployment of simulation-based assessments, helping to identify at-risk drivers and improve overall roadway safety.
Key finding
All ten senior participants passed their in-vehicle clinical evaluations, whereas simulator performance scores were lower and correlated with simulator sickness symptoms, indicating that current simulator hardware may not yet accurately reflect real-world driving competence for this demographic.
