Abstract Pennsylvania Department of Transportation (PennDOT) used Part C of the Highway Safety Manual (HSM) to develop State-specific safety performance functions (SPFs). For some facility types, PennDOT calibrated the SPFs at the district or regional level within the State. PennDOT believes that pre-selecting applicable CMFS, and developing State-specific and regionally calibrated SPFs offers the best approach for addressing the State’s unique features and for dealing with the inherent differences among areas within the State. As the list of countermeasures in the CMF Clearinghouse continues to grow, practitioners can use the criteria to select from among the newly added CMFs.
