Older Drivers' Pedal Behaviors

This project collected data on driver pedal behaviors that may contribute to pedal errors. Participants included four groups of drivers: those diagnosed with mild cognitive impairment; with peripheral neuropathy; orthopedic patients who had injuries or surgery involving lower extremities; and a control group whose members did not have any of these conditions. Participants drove a vehicle instrumented with cameras focused on the drivers’ feet, as well as sensors in the brake and accelerator pedals to provide detailed information about how drivers use the pedals during real-world driving. A driving rehabilitation specialist accompanied participants as they complete a course that incorporated situations that the earlier study showed to be associated with pedal errors. Analyses of the data explored relationships between factors related to the driver and specific driving tasks and drivers’ foot movements (e.g., moving the right foot back and forth above the brake and accelerator) that could increase the likelihood of a pedal error. Findings from this study will be useful in developing countermeasures to reduce pedal application error crashes.
