Abstract:This report documents the Safety Measurement System (SMS) methodology developed to support the Comprehensive Safety Analysis 2010 (CSA 2010) Initiative for the Federal Motor Carrier Safety Administration (FMCSA). The SMS is one of the major tools for measuring the safety of individual motor carriers and Commercial Motor Vehicle (CMV) drivers. Such measures help identify and monitor safety problems as part of the CSA 2010 safety improvement process. The SMS design builds on the lessons learned from developing and implementing SafeStat for Compliance Reviews (CR) prioritization. However, the SMS also incorporates new CSA 2010 requirements for identifying specific types of unsafe behaviors that the entities exhibit. A more specialized set of interventions will now address these unsafe behaviors and the system will also expand the use of on-road safety violation data. In January 2008, FMCSA started an Operational Model (OM) Test of the CSA 2010 Initiative, which includes using the SMS to identify and monitor unsafe carrier and CMV driver behavior. Version 1.2 of the Methodology incorporates feedback from the OM Test and was implemented in the OM Test in April 2009. This revision further clarifies some of the SMS features originally documented in April 2009, but does not represent any changes to the methodology. Future SMS development will be part of a continuous improvement process based on results and feedback from this OM Test.
