Summary

This pilot study, conducted by the Virginia Tech Transportation Institute for the National Highway Traffic Safety Administration (NHTSA), addresses the rising proportion of motorcycle fatalities in traffic crashes. While naturalistic driving studies have successfully identified behavioral factors in car and truck crashes, similar data for motorcycles was lacking. The research aimed to evaluate the feasibility of adapting instrumentation techniques from light- and heavy-vehicle studies to collect naturalistic on-road behavioral data from motorcyclists. The primary motivation was to determine if such instrumentation could answer high-priority NHTSA research questions regarding rider exposure, gaze behavior, evasive maneuvers, and crash causation. The study involved three participants who rode instrumented motorcycles for a total of over 3,100 miles between September 2008 and February 2010. The data acquisition system (DAS) recorded continuous sensor data, including three-axis acceleration, yaw, pitch, roll, geographic location, rear-wheel speed, lane position, turn-signal use, braking, and range/closing speed to forward objects. Five video views were also captured. The researchers attempted to develop helmet-mounted eye-tracking and three-dimensional head-tracking instrumentation to measure gaze location. Study procedures, including recruiting, screening, and garage protocols, were tested. An independent evaluator reviewed the technical approach, instrumentation, and data quality. The results demonstrated that the adapted instrumentation successfully supported the majority of NHTSA’s motorcycle research questions. The system effectively captured kinematic data, rider inputs, and environmental context, allowing for the analysis of events such as intersection approaches and braking profiles. However, the development of fine-resolution gaze tracking instrumentation was not successful in naturalistic settings. While precise eye-gaze measurement failed, the system could identify coarse scan behaviors, determining general areas where riders were looking (e.g., forward, left, right, down, or rearward). The independent evaluation confirmed that the Virginia Tech Transportation Institute’s technical approach was sound, though it noted limitations in the eye-tracking components. The significance of this study lies in its validation of naturalistic data collection methods for motorcycles, a critical step for understanding rider behavior and exposure in real-world conditions. The successful adaptation of most sensors provides a foundation for future large-scale studies aimed at identifying factors contributing to motorcycle crashes. The findings suggest that while precise gaze tracking remains a challenge, coarse gaze data combined with kinematic and video data can effectively address key safety questions. The study also provided insights into participant recruitment and compensation preferences, indicating that future studies are feasible. These results support the development of targeted countermeasures and inform the design of subsequent phases of motorcycle safety research.
