Abstract:The Light Vehicle-Heavy Vehicle Interaction (LV-HV) Data Collection and Countermeasure Research Project
leveraged data from the Drowsy Driver Warning System Field Operational Test (DDWS FOT) to investigate a
set of research issues relating to driver performance and crash causation, and not directly related to the safety
benefits of the DDWS. The four priority issues and study topics selected for exploratory investigation and
analysis included:
• Analysis of HV safety events, including LV-HV vehicle interactions.
• Assessment of crashes and near-crashes, and identification of countermeasures.
• Identification of driving patterns and work/rest schedules.
• Calculation of driver risk.
The data collected in the DDWS FOT between May 2004 and May 2005 encompassed approximately 50,000
hours of naturalistic driving (ND) completed by 95 volunteer commercial driver participants. The collection of
additional data from other commercial motor vehicle (CMV) drivers in different operational settings
(employing a more extensive set of event analysis variables) is planned for the future.
