Summary
This study investigates the time required for older drivers to adapt their steering control to a fixed-base driving simulator, addressing a critical gap in experimental driving research regarding objective adaptation metrics. The authors hypothesized that older drivers achieve maximum training benefit within the first few minutes of simulation, noting that previous studies relied on subjective judgments and varied practice sessions lasting 5–15 minutes. The research aimed to determine if driving behavior in the initial minutes is representative of actual performance or if a specific adaptation period is necessary. The experiment utilized the Simulator for Interdisciplinary Research in Ergonomics and Neuroscience (SIREN), a high-performance simulator featuring a 1994 GM Saturn, a 150-degree forward field of view, and electronic sensors for performance recording. Thirteen participants, all over 65 years of age, drove for 25 minutes on rural, two-lane roadways with traffic. To evaluate adaptation, the researchers extracted three one-mile sections of uneventful driving from the start, middle, and end of the drive. They employed a six-degree steering wheel reversal criterion, defining a reversal as a deflection away from and back to the neutral position. Steering reversals exceeding six degrees were used as an indicator of impaired control and high cognitive load, distinguishing them from intentional maneuvers like curve negotiation. The results demonstrated significant decreases in both the frequency of large steering reversals and overall steering variance between the first segment and the subsequent segments. In the first segment, drivers averaged 10.40 deviations greater than six degrees per minute, compared to 2.86 in the second segment and 3.57 in the third. Statistical analysis using Wilcoxon signed rank tests confirmed significant differences between the first segment and the later segments (p=0.003 and p=0.008, respectively), while no significant difference existed between the second and third segments. Time-series plots revealed that most drivers fell within the six-degree criteria after approximately two minutes, with nearly all participants staying within bounds after three minutes. The study concludes that older drivers require approximately three minutes to adapt to the simulator and establish a stable "feel" for vehicle control. Driving behavior prior to this period may not accurately reflect actual driving performance. These findings provide preliminary empirical support for the assumption that an adaptation period as short as five minutes is sufficient for drivers to adapt to the simulator environment and drive normally. This offers a standardized, objective metric for future driving simulator research, potentially reducing unnecessary practice time while ensuring data validity.
