Summary
This report details the Federal Motor Carrier Safety Administration’s (FMCSA) independent evaluation of the waySmart® 820 onboard monitoring system (OBMS), a non-video-based driver monitoring technology. The study was motivated by the high prevalence of driver error in large truck crashes, specifically decision errors like speeding and low seatbelt usage rates among commercial motor vehicle (CMV) drivers. The primary objective was to determine if the OBMS performed reliably, improved driving safety and performance, and enhanced fuel efficiency in a real-world, revenue-producing fleet environment. The research, conducted by the Virginia Tech Transportation Institute, employed a two-phase methodology. First, controlled performance testing was conducted on the Virginia Smart Road to verify the system’s operational capabilities and its connectivity to the NextGen data acquisition system. Second, a naturalistic field study was implemented within a commercial fleet using an A2B4 design, consisting of a two-month baseline period followed by a four-month intervention period where the OBMS provided real-time audible feedback for speeding, aggressive driving, and seatbelt violations. The system utilized kinematic sensors and global positioning system data rather than video monitoring. The results indicated that the OBMS was highly reliable, accurately detecting speeding violations 86% of the time and seatbelt violations 100% of the time. During the initial two-week intervention period, there was a significant reduction in speeding violations (37%) and seatbelt violations (56%) compared to baseline levels. However, the study found no significant reduction in the overall rate of safety-critical events (SCEs), such as crashes or near-crashes, per 10,000 miles. Fuel efficiency results were inconclusive. Notably, the reduction in speeding violations diminished toward the end of the study, correlating with inconsistent fleet manager coaching and limited use of the system’s reporting tools. Drivers reported positive acceptance, finding the system easy to use and beneficial for performance improvement. The study concludes that while the OBMS effectively monitors specific behaviors like speeding and seatbelt use, its broader impact on safety-critical events is limited without consistent managerial engagement. The findings suggest that the technology’s effectiveness is heavily dependent on regular fleet coaching and driver feedback. Recommendations include the need for standardized vehicle dynamic thresholds for aggressive driving detection and the development of robust coaching programs to sustain long-term safety improvements. The report highlights that while the technology is a useful resource for fleets, its potential benefits are only realized when paired with rigorous management interaction.
Key finding
The OBMS significantly reduced speeding violations by 37 percent and seatbelt violations by 56 percent during the intervention period, but did not significantly reduce the rate of safety-critical events.
