Summary

This study investigates the impact of motorcycle rider training and experience on visual scanning behaviors, specifically focusing on sight distance techniques. Motivated by the high fatality rates among motorcyclists and the lack of empirical data regarding how training affects naturalistic riding behavior, the research aimed to determine if visual behavior differs between beginner riders who received training, those who did not, and experienced riders. Additionally, the study sought to demonstrate the feasibility of collecting naturalistic eye-tracking data from riders using their own vehicles. The researchers employed a longitudinal experimental design involving three groups: seven beginner-trained riders (who completed the Team Oregon Basic Rider Training course), twelve beginner-untrained riders (novices without formal training), and twelve experienced riders (minimum five years and 15,000 miles of experience). Data were collected over three sessions spanning one year on both a closed skills course and a 9.4-mile open road route in Portland, Oregon. A custom portable data acquisition system was developed, utilizing a Giga Bit-E eye tracker, GPS speed sensors, and inertial measurement units to monitor head motion, gaze movement, motorcycle speed, and orientation. Beginner-trained and experienced riders received feedback on their sight distance performance after each session, whereas beginner-untrained riders did not. The results revealed distinct differences in visual behavior among the groups. On the curved sections of the open road course, beginner-untrained riders exhibited a sight distance to stopping distance ratio below 1.0 more than twice as often as the other two groups, indicating they frequently looked ahead a distance shorter than what was required to stop safely. Furthermore, beginner-untrained riders scanned a significantly larger visual area (measured by the 95% confidence ellipse) than experienced riders on the open road, suggesting less focused scanning patterns. In terms of performance, beginner-trained riders rode faster on the closed course curves, while experienced riders were faster on the open road curves. All groups improved their handling skills on the closed course over time, with experienced riders consistently outperforming novices. The study concludes that it is feasible to collect naturalistic eye-tracking data from motorcycle riders in real-world conditions. The findings suggest a relationship between training, feedback, and visual behavior, with trained and experienced riders demonstrating safer sight distance practices compared to untrained novices. These results imply that rider training programs emphasizing visual scanning techniques may effectively improve hazard perception and riding safety. The research provides a foundation for further investigation into how specific training interventions can mitigate risks associated with novice riding.

Key finding

Beginner-untrained motorcycle riders exhibited a sight distance to stopping distance ratio below 1.0 more than twice as often as trained and experienced riders on curved open road sections, indicating they were not looking far enough ahead to stop safely.
