Ive seen the term “Accident Modification Factor” (AMF) before. Is that different than a Crash Modification Factor?
Aside from the name, Accident Modification Factor is the same thing as Crash Modification Factor (i.e., AMF of 0.80 = CMF of 0.80). Although the CMF Clearinghouse does not use the term “AMF”, there are instances of its use in various areas of the safety field. For example, early drafts of the Highway Safety Manual used the term “AMF”, but the decision was made to change the terminology to “CMF” for the final publication.
