  • Abstract:
    This report presents the final results of an independent evaluation of the U.S. Department of Transportation (USDOT) Mack Intelligent Vehicle Initiative (IVI) Field Operational Test (FOT). The IVI is a cooperative effort to conduct FOTs of advanced intelligent vehicle safety systems (IVSS) among the motor carrier industry and four agencies of the USDOT: the Federal Highway Administration (FHWA), the National Highway Traffic Safety Administration (NHTSA), the Federal Transit Administration (FTA), and the Federal Motor Carrier Safety Administration (FMCSA).

    This report summarizes the results of an independent evaluation of the Mack FOT, which was performed under a cooperative agreement with Mack Trucks, Inc., in partnership with McKenzie Tank Lines. The FOT focused on the testing of a lane departure warning system (LDWS). The LDWS is a forward-looking, vision-based system that provides the driver an audible warning of a lane departure situation. Algorithms within the LDWS interpret video images of the lane to estimate the vehicle state (lateral position, speed, heading, etc.) and the road alignment (lane width, road curvature, etc.). By providing lane departure warnings, this system can potentially reduce single-vehicle roadway-departure (SVRD) crashes, rollovers, and lane-change/merge crashes by giving the driver an opportunity to change driving behavior before making a large lane excursion.
