Abstract:An independent evaluation of a non-video-based onboard monitoring system (OBMS) was conducted. The objective was to determine if the OBMS system performed reliably, improved driving safety and performance, and improved fuel efficiency in a commercial motor vehicle (CMV) operation. The study involved a controlled test on the Virginia Smart Road and a naturalistic field test with a CMV fleet. Controlled testing demonstrated capabilities for the field test. The field test demonstrated OBMS reliability with positive effects for safety but inconclusive effects for fuel efficiency. A reliability analysis indicated the OBMS provided speeding and seatbelt violations accurately 86 and 100 percent of the time, respectively. An analysis using the rate of safety-critical events (SCEs) per 10,000 miles found no reduction in SCEs from intervention to baseline. However, a trend analysis of violation frequency per 1,000 miles over vehicle operation weeks showed a significant drop in speeding violations (37 percent) and seatbelt violations (56 percent) from the baseline phase to the first 2-week intervention period. A subset of participating drivers in the field study were surveyed and indicated the OBMS was easy to use and felt it had a positive impact on their performance. Recommendations are presented for both system providers and fleets.
