While SafeStat was designed to prioritize carriers for monitoring and compliance reviews, the ISS was designed to prioritize carriers for roadside inspection. However, both algorithms use similar data to define a relatively unsafe carrier. It would be beneficial if there could be one uniform motor carrier rating system in place for all of the Federal Motor Carrier Safety Administration's programs. This paper briefly describes the two algorithms, discusses the integration of the SafeStat algorithm into the ISS, and presents conclusions of the initial testing of the resulting system, ISS-2.
