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.
