Summary
This report details the development and pilot testing of the Older Driver Support System (ODSS), a smartphone-based application designed to provide real-time safety feedback to older drivers. The research was motivated by the critical link between driving ability and independence for older adults, noting that age-related declines in vision, hearing, cognitive processing, and physical strength increase crash risk. While educational programs exist, they lack real-time intervention capabilities. The project aimed to determine if automated, real-time feedback could mitigate these risks and support safer driving behaviors. The methodology comprised four tasks. First, researchers interviewed three Certified Driver Rehabilitation Specialists (CDRS) to identify common older driver limitations—such as reduced spatial awareness, memory deficits, and slow reaction times—and the coaching strategies used to address them. Second, based on these interviews, the team developed a functional design specification for the ODSS. The system utilized smartphone sensors (GPS and inertial measurement units) to deliver three types of feedback: location-based information (e.g., upcoming intersections, speed limits), behavioral warnings (e.g., excessive speed, insufficient speed, harsh braking/acceleration), and pre-drive reminders (e.g., checking mirrors, lane positioning). Specific thresholds for warnings were established, with distinct parameters for daytime and nighttime driving to account for visibility differences. Third, the software was programmed and validated through researcher-driven test runs. Finally, a pilot test was conducted with three older drivers (age 65) and two CDRSs. Participants rode as passengers while a researcher drove a predefined 10-mile route in College Station, Texas, allowing them to observe the system’s alerts without driving distractions. The pilot test focused on usability and perceived value rather than crash reduction metrics. Participants provided feedback via a "think out loud" protocol during the drive and completed evaluation questionnaires afterward. The system successfully triggered various alerts, including speed limit updates, warnings for excessive maneuvers, and notifications for upcoming traffic control devices. Participants rated the system’s usability and provided comments on the clarity of audio and visual cues. The study identified potential benefits, such as improved situation awareness, and noted areas for improvement, including suggestions for adjusting warning frequency and content to reduce distraction. The significance of this work lies in the creation of a functional prototype that translates professional driving rehabilitation strategies into automated, real-time feedback. The findings suggest that such systems have the potential to help older drivers compensate for physiological and cognitive declines, thereby extending their driving independence and safety. The pilot test results provide a foundation for future iterations, emphasizing the need to refine feedback timing and personalization to ensure the system supports rather than distracts the driver. This project demonstrates the feasibility of using existing smartphone technology to address specific safety challenges associated with aging drivers.
