New Risk Management Study Findings Recently Were Reported by Researchers at University of Central Florida (A new approach for calibrating safety performance functions)

By a News Reporter-Staff News Editor at Insurance Weekly News -- Data detailed on Risk Management have been presented. According to news reporting originating in Orlando, Florida, by VerticalNews journalists, research stated, "Safety performance functions (SPFs) are statistical regression models used for estimating crash counts by roadway facility classification. They are required for identifying high crash risk locations, assessing the effectiveness of safety countermeasures and comparing road designs in terms of safety."

Financial support for this research came from NCHRP 17-62.

The news reporters obtained a quote from the research from the University of Central Florida, "Roadway agencies may opt to develop local SPFs or adopt them from elsewhere such as the national Highway Safety Manual (HSM), provided by the American Association of State Highway and Transportation Officials. The HSM offers a simple technique to calibrate its SPFs to conditions of specific jurisdictions. A more recent calibration technique, also known as the calibration function, is similar to that of the HSM. In this research, we develop SPFs of total crashes for rural divided multilane highway segments in four states. The states are Florida, Ohio, California and Washington. We also calibrate each SPF to each state using the HSM calibration method and the calibration function. Furthermore, we propose the use of the K nearest neighbor data mining method for calibrating SPFs."

According to the news reporters, the research concluded: "According to the goodness of fit (GOF) results, our proposed calibration method performs better than the other two methods."
