摘要：	SafeStat (Safety Status Measurement System) is an automated analysis system developed for the Federal Highway Administration's Office of Motor Carriers (OMC) that combines current and historical safety data to measure the relative safety fitness of interstate motor carriers. SafeStat enables OMC to quantify and monitor the safety status of motor carriers and guides the deployment of resources to focus on carriers posing the greatest safety risk. SafeStat resulted from research performed by the U.S. Department of Transportation's Volpe Center for OMC to improve motor carrier safety fitness assessment and prescribe actions for correcting safety deficiencies. SafeStat initially was developed and implemented as part of a federal-state pilot program. It has been implemented nationally by OMC to identify and rank individual motor carriers for on-site safety compliance reviews. An effectiveness study was devised to confirm that SafeStat-identified carriers were high-safety-risk carriers. Postidentification carrier crash experience was examined and SafeStat's effectiveness was tested by comparing the crash rates of identified and nonidentified carriers. The effectiveness study shows that SafeStat identifies carriers likely to have significantly higher crash rates than carriers not identified. Specifically, the carriers designated in the highest "at risk" category by SafeStat had a much higher crash rate (169% higher) following their identification than carriers not identified as safety risks. In addition to confirming SafeStat's effectiveness, the results of the study enable SafeStat developers and OMC to assess the relative strengths of SafeStat's components and to continue enhancing its efficiency.
