• Abstract:
  This study was conducted by the University of Michigan Transportation Research Institute
  
  (UMTRI) under a Cooperative Agreement between NHTSA and Meritor WABCO to examine
  
  the performance of electronic stability control (ESC) systems, and roll stability control (RSC)
  
  systems for heavy-truck tractor-semitrailers. The study is based on the analysis of independent
  
  crash datasets using engineering and statistical techniques to estimate the probable safety
  
  benefits of stability control technologies for 5-axle tractor-semitrailer vehicles. The
  
  conventional approach for assessing the safety benefits of vehicle technologies is to analyze
  
  crash datasets containing data on the safety performance of vehicles equipped with the
  
  technology of interest. Because the deployment of the stability technologies for large trucks is
  
  in its infancy, national crash databases do not yet have a sufficient amount of factual data that
  
  can be directly linked to the performance of the technology. Therefore a novel method of
  
  examining the potential benefits of these systems was used. Crash scenarios that could likely
  
  benefit from the technologies were selected from national crash databases and the probable
  
  effectiveness of each technology was estimated. The analysis in this study did not have the
  
  advantage of examining representative crash datasets that contain identifiable data from vehicles
  
  equipped with the technology. Therefore, the analysis was based on probable outcome
  
  estimates derived from hardware-in-the-loop simulation, field test experience, expert panel
  
  assessment, and fleet crash data and these methods were used to estimate the safety benefits
  
  from the national crash data population.
