Abstract:

The Highway Safety Manual (HSM) provides statistically-valid analytical tools and techniques for quantifying the potential effects on crashes as a result of decisions made in planning, design, operations, and maintenance. Implementation of the new techniques in the HSM will upgrade FDOT’s safety analysis methods from descriptive methods to quantitative, predictive analyses. However, the base models for the HSM safety prediction methodologies were developed with data from specific highway agencies from different parts of the country. To apply these models to geographic regions in Florida and to account for changes in crash trends over time within the same geographic region, calibrations of these base models is required. This study provides these calibration factors the segment- and intersection- level safety performance functions from the HSM for Florida conditions or the years 2005 through 2008. The calibration factors provided in this report are to be used along with the appropriate SPFs for project-level safety analyses conducted in the state of Florida.
