• Description:
  Objective: The objective of this naturalistic driving study was to determine whether two types of feedback (instant feedback from an on-board video recording system (OVRS) and one-on-one coaching between supervisors and drivers) reduced risky driving behaviors in box-truck drivers. Methods: The driver population drove box trucks, delivering goods to convenience stores. This study used an on-board video recording system (OVRS) with forward-and driver-facing cameras which recorded driver behaviors, and accelerometers that detected vehicle maneuvers such as hard braking, acceleration, and speeding. When a vehicle event was triggered by a harsh maneuver, the OVRS saved a 30-second video/audio clip, 15 seconds before and after the triggering event. The videos were viewed by the OVRS vendor's trained observers and coded for approximately 60 different risky driving behaviors of varying severity. Two types of feedback to the drivers were evaluated: instant feedback from lights on the dashboard that flashed yellow or red to denote harsh vehicle maneuvers, and one-on-one coaching between supervisor and driver, consisting of viewing the recorded video events involving the driver and discussing safe driving behaviors. All trucks at seven business sites were equipped with OVRS, for a total of 158 OVRSs at the start of the study. The seven sites were assigned to an intervention group (n=5) that received instant driver feedback and supervisory coaching, or control group (n=2) that received no feedback. The data presented here cover 17 months of monitoring using OVRS in the intervention and control groups. Results: Over the 17 months, there were approximately 237,000 useable trigger events recorded. Driving unbelted was the most common risky behavior; using hand-held electronic devices ranked 4th . Coaching varied among the sites, from a low of 52% of the drivers that should have been coached at one site to a high of 96% at another. The rate of overall risky driving behaviors decreased significantly in the intervention (lights plus coaching) group (RR=0.47, p<0.001), with no significant change seen in the control group (RR=0.93, p=0.44). Conclusions: Preliminary results show that the OVRS intervention was associated with a decrease in risky driving behaviors that may reduce collisions, injuries and fatalities.
