Calibration of HSM Predictive Methods on Rural State and Local Highways

Defining safety performance expectations is a challenge for transportation agencies. The Highway Safety Manual (HSM) of the American Association of State Highway and Transportation Officials (AASHTO) provides guidance for safety analysis using scientific and statistically sound methods. Given the expense of engineering studies and limited funding, safety reviews based on expected safety performance are a useful way to identify hot spots in a highway network as well as sight-specific safety problems. Predictive crash models, as formulated in Equation 1, pinpoint sites with great promise for crash reduction on the basis of decades of safety research and statistical analysis.
