Truck Roll Stability Data Collection and Analysis
Truck rollover is a serious highway safety problem. Each year, of all commercial
vehicle occupant fatalities, about 50% are the result of a truck rollover crash. In addition, significant traffic
disruption often results from truck rollover, and the severity of incidents can be sorely multiplied by the type
of cargo involved. It is, therefore, important to seek ways to avoid such accidents. In the future, the most likely
means to prevent rollover crashes is a warning system, combining vehicle components and highway geometry, which
can warn truck drivers of impending rollover danger in time for them to take corrective actions.
The ITS Joint Program Office, working with the Oak Ridge National Laboratory (ORNL), the University of Tennessee
Transportation Center, Tennessee Department of Transportation (TDOT), and private industrial partners including
U.S. Xpress, Praxair, Control by Light, and Volvo Trucks, collected and analyzed data using trucks in revenue service.
Results of the Truck Roll Stability project indicated that data collected by instruments located on both the truck
and the trailer can support a driver warning system. The instrumentation and methodologies which were used in this
project demonstrated how ITS technologies can be used to enhance operations, improve safety, and increase the understanding
of the tremendous potential for the early deployment of the Intelligent Vehicle Initiative (IVI) on commercial
operations.
